Did Hinduism, Christianity, Islam and Judaism Copy from Each Other?

Every culture has influenced every other culture during mutual interactions. It is only because of this influence that humanity has achieved a lot. But many people today call such cross-cultural interactions, influences, adaptations etc as ‘copying’ or ‘plagiarism’ which is both sad and stupid.

For example, today Indians wear shirt and pant, celebrate birthdays using English calendar, cut cakes and blow candles etc. Should we say India copied this from West or West influenced India?

Of course, a lot of Catholic churches and many Sufis have adapted certain cultural things from India as well. So yes, Indian culture has influenced Indian Christians and Indian Muslims. There is no question about it. Have you ever wondered why the Bible is called as Vedagamam in Tamil? It is not plagiarism but influence! Plagiarism or copying means a person using somebody’s work without attribution. This doesn’t apply to cultures.

Let me give you a lot of examples:

  1. The story of Adam in Bible is heavily influenced by Enkidu from the Sumerian Epic of Gilgamesh.
  2. The story of Noah and Manu was influenced by the great flood in the epic of Gilgamesh.
  3. The old testament doesn’t have the concept of hell or heaven. The divine justice is delivered on earth itself, which is indicated by fall or rise of states. This idea of divine justice was also borrowed from Sumerian-Mesopotamian cultures.
  4. The idea of Good and evil (Satan) in Bible was adapted from Persian religion; and Persian religion itself heavily borrowed from early Vedic religion.
  5. Vedic religion itself adapted many deities from other cultures: Dyaus, Usas and Ashvins come from proto-Indo European culture. Indra and Soma come from Bactria-Margiana culture. And according to Asko Parpola, Varuna was a deity native to Indus valley civilization ( I am a little skeptical of Parpola’s claim though).
  6. There was an ancient University in Taxila founded in 10th century BCE which should have certainly attracted students from all over the world, Even though majority of the people were unaware of other states and empires, there were certainly elites and traders who travelled long distance from the Near East. It is through the influence of this University, many ideas which existed in cultures close to it has travelled to far away lands. A lot of such ideas got distorted, modified, re-interpreted and even developed in the places where they reached. I see no other reason for development of new ideas during Axial age ( 800 BCE to 300 BCE) all over the world.
  7. Early Vedic religion did not have the concept of samsara, moksha or karma. But some individual rishis of Rig Veda might have been aware of such ideas already. These ideas were influenced by Sramana traditions and re-interpreted within Vedic context. Also, early Vedic religion neither had temples or idols.
  8. The stance against idolatry in Judaism was strongly influenced by the representation of the king and the state through images in Egypt . So, the stance against idolatry has a hidden and lost message: Do not consider a human being as infallible authority! But the Hebrew Bible is a theological and mythological narrative to explain real political events, such as the conquery of Israel by Assyrians, Babylonians, Persians and others. Along with this, Jewish mysticism which is close to Eastern traditions existed and their ideas also influenced the old Testament.
  9. Followed by Taxila university, Plato’s academy was established in Greece in c. 387 BC in Athens. The idea of eternal hell was developed by Plato as a social tool to discipline people who wouldn’t listen to reason. Later it was adopted by Abrahamic traditions. Plato’s allegory of cave is another metaphorical distinction between real and unreal, just like Vedanta.
  10. Muhammad travelled from Mecca to Damascus every year for trading. In Damascus, he must have been exposed to various mystical traditions. No, he didn’t copy them. He simply brought it to Arabia which by that time had no state, no law, and no justice; People had primitive social norms, killed female infants, raided caravans, married irresponsibly and abandoned orphans and widows. Once thing I can infer is, the intellectual gap between Muḥammad and his followers was very large. As historians agree, Islam indeed improved the status quo of pre-Islamic Arabia and was an improvement to the existing conditions . So many ideas which we think from Islam were already existing before Islam; Muhammad just managed to reform some of them but compromised and adapted some olden values too.
  11. Vedic religion had a concept of Rna or indebtedness. It simply means human beings are obligated to follow a law or Dharma and settle the debts he owes for the society and nature. Failure to do so simply means a lack of gratitude. Dharma means law or way of life. Initially, Dharma was only about ethics and order, wealth and pleasure. But after being influenced by Sramana traditions, Dharma also included the way to attain eternal peace. They came up with three means to do that: karma (doing your obligatory duties without being too attached to the fruits of actions), Jnana (a direct inquiry into the nature of existence) and bhakti (surrender and love to one and only supreme God). Now let us see how all this fits into Islam. Muhammad did not call Islam as a religion but called it as Deen. It means law or way of life, just like Dharma. And the word comes from Arabic for ‘dayne’ which means ‘debt’ (just like rna). And Muḥammad insisted that submission to God as true form of worship. Jihad means struggle, which is the same as Srama in Sramana. And the word ‘khafir‘ originally meant someone who lacked gratitude or someone who hides the truth. If you put together all the pieces and see the whole picture, it will make a lot of sense.

12. Muhammad did not claim that he was bringing something new. He simply claimed he was restoring the original form of worship by Abraham. Who is Abraham? People have noticed strong similarity between Abraham and Brahma and have suggest that Jews and Brahmins were the same. A passage that is quoted often for this is:

“The similarities between the names of Abraham and Brahma have not gone unnoticed. Abraham is said to be the father of the Jews, and Brahma, as the first created being, is often seen as the father of mankind…’ We might also note that the name of Brahma’s consort Sarasvati seems to resonate with that of Abraham’s wife, Sarah [… each one’s identity as a wife and/or sister]. Also, in India, the Sarasvati River includes a tributary known as the Ghaggar…. According to Jewish tradition, Hagar was Sarah’s maidservant…. Both Brahmins … and Jews see themselves as the ‘chosen people of God.’ The Hebrews began their sojourn through history as a ‘kingdom of priests’ (Exodus 19:6). Likewise, Brahmins are also a community of priests. — Rosen in Essential Hinduism, p. 12.”

But I don’t think it is true; there is strong evidence against it. It will make more sense to consider Abraham as a metaphor for a Brahmin who lives between the rivers Sarasvati and Ghaggar. So who is the God of Abraham? It is more likely to be the fusion of aspects of Vedic deities Rudra and Varuna. When I was researching the origins of devotion or bhakti, I was able to trace it back until Varuna, who is described as the Lord of justice, expects surrender and repentance, just like Abrahamic God. And just like God asks Abraham to sacrifice his son, Varuna asks Harischandra to sacrifice his son. Later, the benevolent deity Yahweh (who is similar to Rudra, later syncretized with Shiva) absorbed all aspects of hundreds of older Jewish deities and the aspects of God of Abraham too. This also makes sense, because the same story about human sacrifice make a re-entry in India through a Tamil Text ‘Periya Puranam’ several centuries later. And this time it is Shiva (who absorbed Vedic Rudra) who comes in disguise as a sadhu and asks for human sacrifice of his son. Makes sense?

13. The lost or unknown years of Jesus in the Bible between the age 12–30 has been explained by many by saying that he has travelled the world, including Indian subcontinent. There is a document in monastery in ladakh which actually talks about Jesus studying there and it has been witnessed and translated by many. Jesus also said that he came to establish the Law (Halakha in Hebrew, which means the same as Dharma).

14. All cultures evolve their dharma like this: an animistic tradition that doesn’t have a concept of God but only believes in various spirits inside real world objects —-> Clan deities of various tribes forming a pantheon, sacrificial rituals and accompanying poetry — Evolutionary monotheism which happens by syncretism of various deities into one —-> Worship and surrender to one supreme God with names like Ishvara, Allah, Narayana etc. —-> The mystical path that involves realizing God as all that exists (Brahman, which is usually thought a direct result of worship and surrender to one God, along with Karma and Jnana. In Islam, there is Sufism; in Christianity there is Christian Mysticism; in Judaism, there is Jewish Mysticism and Hasidism. They all start with surrender and worship in the beginning of the path but also talk about the higher truth of oneness of Brahman; But since they use different names and concepts, use different teaching methods, enumerate the contents of consciousness differently (which is nothing but the actual meaning of Samkhya) and also define the stages of the spiritual paths differently, they all seem different. In addition to it, there are cultural, historical, political, linguistic, and geographical differences which has all been wrapped as a package to come up with the modern concept of religion .

15. Apart from Vedic and Sramana traditions, there were thousands of folk traditions with thousands of deities in India. Many were benevolent but absorbed into Buddhist mythology as yakshas and yakshinis who were the disciples of Buddha. They are also seen as various extensions of one reality in meditation. Vedic religion did the same thing by Sanskritizing all these deities and absorbing them into Shiva or Vishnu; if they were female deities, they merged with Shakthi or Lakshmi. And Shiva and Shakthi are again considered as two aspects of one divinity. Many people, especially from South of India think that this is bad. No, it is really not; the only negative consequence of this was denying entry and access to temple worship to people of specific social class. This is similar to ancient Egyptian tradition in which priests were the only ones who had access to temples and other people can only see the deity during processions. This Sanskritization of folk deities led to various monotheistic traditions like Shaivism and Vaishnavism, which were all united by Adhi Shankara as various paths of single dharma.

16. If you stop seeing things with modern lens using modern concept of religion, you can see the truth; if you take this modern concept as your identity and tend to feel superior towards it, it will certainly lead to intolerance. But if you go to the roots and see that it is all about dharma and its three aspects (bhakti, jnana and karma), then everything will be clear. You will agree with what I have written in this post: Shanmugam P’s answer to Why is Hinduism spreading so fast all over the world?

The Metaphoric Explanation of the Holy Bible – Discovering True Christianity

20190831_065349_0000.png

We tend to interpret the scriptures the wrong way when we take them literally. But scriptures are full of metaphors. It is said that God breathed his breath into man. The Holy Spirit comes from the Greek word ‘pneuma’ which means ‘breath’. Holy spirit is the same as Prana, Shakti and Kundalini in Hinduism. It is what animates the world and the human beings. But inside the human beings it is dormant. By spiritual practice involving unconditional devotion and meditation, we purify ourselves and let the holy spirit be revealed and fill our entire being. This is the meaning of getting baptized by the Spirit. The fall of Adam and Eve is a beautiful metaphor that indicates how the oneness of childhood is lost by the birth of duality. This happens to everyone. Exodus is the symbolism of the journey from bondage to liberation. Crucifixion is the death of the duality. And resurrection is the birth of Christ consciousness, the spiritual rebirth which brings the gifts of the Holy Spirit. It is called as Jnana in Hinduism.

This doesn’t mean that the stories in Bible didn’t happen. They just didn’t happen exactly the way it is explained. Also, there is a strong consensus among historians that Abraham, Isaac, Jacob, Moses and many others were not real people. Archeological research has rendered incredible evidence for the fact that many of the Bible stories are stories and not history. But it also presents the history of Israel in a way that adds juice to the story, even though it is completely different from the actual history. For example, the conquest of Canaan didn’t really happen; but to interpret it in a symbolic way, it symbolizes the conquest of one’s own ignorance, which is also the metaphorical interpretation of Holy Jihad in Islam. United Kingdom of Israel as portrayed in the Bible never existed either.

The Hebrew Bible was written for two purposes. Contrary to what Bible suggests, the entire Torah and the parts of Old testament was written sometime around 8th – 6th Century BCE. A major part was written after the destruction of the first temple in Jerusalem. The first purpose was political: to unite the people of Israel under one God, one temple and one Kingdom. The second purpose is spiritual: to convey truths via metaphors, parables and sayings.

The whole Bible comes under the category of mythology. In fact, only after the birth of Jesus, puranas, the Indian myths were composed. This also suggests that Indian mythology might have been inspired by Christian and Jewish scriptures. Indian myths also try to convey the spiritual truths using metaphors, parables, sayings and in the form of conversation between two people, a guru and a disciple. They do convey a little bit of history directly and indirectly, but many of the stories were added to create an interesting narrative. This narrative was used to unite people and also to kindle the feelings of devotion in the initial stage.

It is said that Quran was revealed to Muhammad by angel Gabriel. But here it is important to understand that even Gabriel is a personification of the Holy Spirit and the revelation by Gabriel is hence symbolic. There are a lot of such symbols in scriptures.

However, historians do agree that Jesus was a historical person. Two incidents which are considered as absolutely real are his baptism by John and his crucifixion.

John Campbell, an American professor of literature, has done a lot of research and has written books on this subject. I haven’t read any of his books yet and hence can’t comment about how efficient his arguments are. But I understood the symbolic nature of myths and scriptures in the light of my own experience.

Is There a Scientific Evidence for Spiritual Enlightenment?

I see a lot of people asking this question.. What does science say about spiritual enlightenment? Is it possible to prove it scientifically? What are the possible neural correlates of nondual awareness? Can there be a scientific way out of suffering?  I have explained the possible scientific explanations for spiritual awakening in my earlier articles  ‘Theory of Enlightenment – by Scientific method’ and ‘Awakening Through Mindfulness – Bridging Science and Spirituality’. But in this article, I am going to elaborate further on the scientific model for spiritual enlightenment and I will mention many significant studies that have been conducted on this topic.

Operational Definition for Enlightenment

Before we attempt to prove that something called enlightenment exists, we need to come up with an operational definition for enlightenment. If you are new to the term ‘operational definition’, I can explain it a little bit for you. First, Operationalization is a process of defining the measurement of a phenomenon that is not directly measurable, though its existence is indicated by other phenomena. Operationalization is thus the process of defining a fuzzy concept so as to make it clearly distinguishable, measurable, and understandable in terms of empirical observations.So, an operational definition for enlightenment should be defined in such a way that it can be easily distinguishable, measurable and understandable by observation.

spiritual enlightenment

The problem with that is, each tradition has its own definition for enlightenment. Even within a single tradition, there are various schools which define it in their own way. It is also very hard to put a lot of subjective aspects in words. Rather than defining enlightenment based on its subjective aspects, it may be easier to define it based on the neural correlates of enlightenment/non-dual awareness which can be observed.

Jake H. Davis, Postdoctoral Associate at New York University published a paper in 2013 titled ‘Can enlightenment be traced to specific neural correlates, cognition, or behavior?‘ in which he discusses this issue in detail. He says that by integrating evidence from neuroimaging with evidence of behavioral transformations specified in particular traditional descriptions of meditation practices, some important obstacles may be mitigated. He talks about various studies which have been previously conducted on people who claim spiritual enlightenment.

Here is what he concludes in the paper:

“It is therefore, necessary to responsibly unpack traditional constructs into common psychological and neurocognitive terms that can correlate with first-person experience with some consistency, but without unwittingly dismissing the deepest and most fundamental features of the practices from which they originate. We are, in the end, cautiously optimistic that progress can be made on well-defined projects in this area that integrate behavior and phenomenology with neuroimaging evidence, but not without a careful consideration of the methodological obstacles. Responsible scientific investigations of enlightenment can proceed only on the basis of rigorous understanding of particular experiential states or behavioral traits within a particular tradition as part of a whole value system, embedded in many other aspects of the models employed in that specific tradition of how the mind works and how awakening progresses.”

Another paper that was published in Scientific God journal was very interesting. Before I talk about the paper, let me tell you what this Scientific God journal does in their own words:

“The purpose and mission of Scientific GOD Journal (“SGJ”) are to conduct scientific inquiries on the nature and origins of life, mind, physical laws and mathematics and their possible connections to a scientifically approachable transcendental ground of existence – we call “Scientific GOD.” By “scientific inquiries”, we mean building concrete and testable models and/or hypotheses connected to hard sciences (e.g., physics, neuroscience, biochemistry and physiology) and doing the experimental testing.

We believe that in this golden age of Science the GOD in whom we trust should be spiritual as well as scientific. Indeed, since we are all made out of the same subatomic, atomic and genetic alphabets, the scientific GOD each of us seeks should be one and the same whatever our race, religion and other differences.”

The paper ‘A Natural Explanation of Spiritual Enlightenment’ published by James Kowal attempts to explain enlightenment and the ultimate reality (non dual consciousness) through quantum physics. Here is the abstract of the paper:

“ Recent developments in theoretical physics, which include attempts to unify the laws of the universe, as in string theory, and attempts to explain the origin of the universe, as in inflationary cosmology, are interpreted in terms of the theater of consciousness mental model of the world. This scientific paradigm dates back to ideas that Plato first discussed in the Allegory of the Cave, and is consistent with the holographic principle of quantum gravity, the many world interpretation of quantum theory, and the Gödel incompleteness theorems. This mental model of the world leads to a natural theory of the mind, and is consistent with spiritual discussions of creation, as found in Genesis, and expressions of nondual wisdom, as found in the Tao Te Ching. A natural explanation of spiritual enlightenment in the nondual sense of ‘no-self’ or ’emptiness’, and the concept of ‘nothingness’ as expressed in Buddhism, Zen and Hinduism, are also discussed.”

If you search for ‘James’ in Scientific God journal you fill find a lot of interesting papers published by him. In those papers, he has discussed many things regarding to consciousness and how the experience of world arises from consciousness.

Identification with the ‘Egoic self’ and the sense of duality

Based on my own experience and based on the essential teachings of various traditions that talk about spiritual enlightenment, there is one thing that I have found which is common in all these traditions. It is all about removing the duality, the solid psychological distinction between ‘me’ and the ‘other’ or ‘me’ vs ‘world’. People who are spiritually enlightened feel that their experience of the reality is nondual and they don’t derive a separate sense of an egoic self based on their life story and their self-concepts.

So, it all boils down to one thing – Change in the perception of self. Let us first discuss various brain functions related to this feeling of separate identity.

Your Brain – The Seat of your Conscious Experience

Before we go further, it is essential to understand the basics of your brain. Your brain has specialized cells called ‘neurons’ which communicate with other neurons through electrochemical signals called ‘Action potentials’. Everything we think, feel and experience is the result of the constant activity in the neural network of your brain.

Let us talk about two distinct parts of the brain – the higher and lower. The upper part of the brain, that is involved in higher cognitive functions is divided into four lobes – Frontal (just behind your forehead), parietal (second half of the top part of your brain, behind the frontal lobe), occipital lobe (in the back of your head) and temporal lobe (two sides of the head, near the ears). Frontal lobe is responsible for executive functions like planning, analysing etc. It has a structure called neocortex which is the recently evolved part of the brain. Your brain also has a lower part that includes limbic system, brainstem and hindbrain which take care of the basic functions of the brain like arousal, sleep, hunger etc. It also prepares the brain to face a threat and initiates the flight or fight response. Amygdala in this region is responsible for emotions such as fear; hippocampus is responsible for forming new memories. This whole lower part is the oldest part of the brain which reminds us that we are essentially animals.

Your upper brain, the cerebral lobes, can be divided into two hemispheres. Each hemisphere dominate the other in certain cognitive functions. This phenomenon is called lateralization of the brain. A very important distinction is language. Your left hemisphere plays a major role in language production and understanding the language.

The Left brain interpreter – The creator of duality and the cause of suffering

Now, let us try to understand what creates the separation between ‘you’ and the rest of the world. This basic categorization is done by our left brain and it can be explained by something called left-brain interpreter. This is what creates categories like ‘you’ vs world, self image vs ideal self, good vs bad etc. The categorization of ‘you’ vs ‘world’ becomes very solid in the long run, as a result of learning and neuroplasticity.

To give you a brief introduction of this left brain interpreter, let me quote from Wikipedia:

The left brain interpreter refers to the construction of explanations by the left brain in order to make sense of the world by reconciling new information with what was known before. The left brain interpreter attempts to rationalize, reason and generalize new information it receives in order to relate the past to the present. The concept was first introduced by Michael Gazzaniga while he performed research on split-brain patients during the early 1970s with Roger Sperry at the California Institute of Technology.] Sperry eventually received the 1981 Nobel Prize in Medicine for his contributions to split-brain research

The drive to seek explanations and provide interpretations is a general human trait, and the left brain interpreter can be seen as the glue that attempts to hold the story together, in order to provide a sense of coherence to the mind. In reconciling the past and the present, the left brain interpreter may confer a sense of comfort to a person, by providing a feeling of consistency and continuity in the world. This may in turn produce feelings of security that the person knows how “things will turn out” in the future.

However, the facile explanations provided by the left brain interpreter may also enhance the opinion of a person about themselves and produce strong biases which prevent the person from seeing themselves in the light of reality and repeating patterns of behavior which led to past failures.The explanations generated by the left brain interpreter may be balanced by right brain systems which follow the constraints of reality to a closer degree. The suppression of the right hemisphere by electroconvulsive therapy leaves patients inclined to accept conclusions that are absurd but based on strictly-true logic. After electroconsulsive therapy to the left hemisphere the same absurd conclusions are indignantly rejected.

Chris Niebauer is a neuroscientist who received his Ph.D. in Cognitive Neuropsychology from the University of Toledo where he specialized in left-right brain differences. He has written a book called ‘The Neurotic’s Guide to Avoiding Enlightenment: How the Left-brain Plays Unending Games of Self-improvement’ in which he explains this left-brain interpreter in detail. This book is based on the teachings of Eckhart Tolle and attempts to integrate his teachings with neuroscience. Let me quote a few lines from his book:

“The interpreter in the left brain has a preference for consistency and little tolerance for ambiguity. There are right and wrong answers and things need to be predictable and orderly.Paradox is a turn-off to interpreter. Left brain is so based in categories, it categorizes everything as right and wrong, good and bad. Categories divide and the interpreter has divided itself into ‘How i am’ and ‘how i want to be’ “

“The left-brain interpreter is categorical, it creates division outwardly and inwardly, so let it do its job, let it do its thing. Here we might ask why you want to go beyond your ego and more importantly, is it your ego that wants this? Because if it is, it can’t. Going beyond the ego is nothing like what the ego thinks it is, how could it be? When the ego tries to drag itself beyond itself it may bring along a little anxiety and conflict, so remember that all scary things are pretend. Also, Alan pointed out in the 70s that the biggest ego trip of all was in believing that one was beyond the ego. Today this is also true but with one more level to it, today there is the ego trip of pointing out that the 6i:4:est ego trip of all is in believing you have gone beyond the ego. The notion that you can improve yourself by going beyond your ego stems directly from the interpretive mind, and as such, is an interpretation that something is wrong and there is something that needs be done about it. Again, there is the interpreter created category of “me as I am” vs. “me as I want to be” which are both just thoughts bouncing around in the skull. So, ironically, if you are trying to improve yourself, you can’t. The notion that your self needs improving is an interpretation and we are going around interpretations. There is an irony in most bookstores called the “self help” section. I might suggest renaming this as “Books that reinforce the illusion that the left-brain interpreter can be what it isn’t free of itself.”

“The interpreter also creates and sustains our collection of categorical thoughts called our beliefs.”

Here the story of Dr. Jill Bolte Taylor is worth mentioning. She is a Harvard-trained and published neuroanatomist who experienced a severe hemorrhage in the left hemisphere of her brain in 1996. This permanently changed her perception of reality.

She says, “It was as though my mind had shifted away from my normal perception of reality—where I’m the person on the machine having the experience—to some esoteric space where I’m witnessing myself having this experience.”

“My perception of physical boundaries was no longer limited to where my skin met air,” she has written in her memoir, “My Stroke of Insight”. The core message of the book is that people can choose to live a more peaceful, spiritual life by sidestepping their left brain. You can read here whole story here.

As we see, the interpreter plays a major role in dividing the reality. It also creates a split between our self-image and our ideal self. We all have a self-concept (called ‘Ahamkar in Indian traditions’) which consists of various beliefs about who we are and what we want to be. As clear borders have been defined for this egoic identity, there is a constant need to protect and enhance this identity. Most of our suffering results from our constant identification with this conceptual entity by giving it a solid reality in our minds. A threat to the self-concept or self-image is perceived by our body and mind like any other threat in the world (like a threat faced by an animal of being killed). So, all of such experiences create the same physiological reactions by activating the amygdala and initiating a fight-or-flight response.We are also in a constant pursuit of enhancing the self-concept by accumulating wealth, knowledge and beliefs about ourselves. We depend on our past to define who we are and we depend on the future to enhance it. Because of this, we are stuck in a hedonic treadmill.

Let me quote from Wiki again to define ‘Hedonic treadmill’

“The hedonic treadmill, also known as hedonic adaptation, is the observed tendency of humans to quickly return to a relatively stable level of happiness despite major positive or negative events or life changes. According to this theory, as a person makes more money, expectations and desires rise in tandem, which results in no permanent gain in happiness. Brickman and Campbell coined the term in their essay “Hedonic Relativism and Planning the Good Society” (1971). During the late 1990s, the concept was modified by Michael Eysenck, a British psychologist, to become the current “hedonic treadmill theory” which compares the pursuit of happiness to a person on a treadmill, who has to keep walking just to stay in the same place’”

Spiritual enlightenment promises to end suffering by ending this hedonic treadmill. It leads one to resolve all the internal conflicts and to feel one with everything. It removes the idea that there is a separate entity inside which has to enhance itself for fulfillment. The left brain may still continue to categorize things, but they are not solidified in our consciousness and urge us to protect those solidified entities.

Neural Correlates of the egoic self

To study about the enlightenment in neuroscientific perspective we have to know about a neural network called ‘The Default Mode Network’ in the brain.

The default mode network (DMN) refers to the structures in the brain which are active when we are not focused on any task in particular. If you are idle, this network is activated by default. This network is activated when we are mind wandering, thinking about others, thinking about one’s self, remembering the past, and envisioning the future. This network has everything to do with the egoic self that we are identified with. The main structures of default mode network are precuneus, posterior cingulate cortex, medial prefrontal cortex and certain other areas.

This indicates that the solid entity of ‘me and my story’ categorized by the left-brain interpreter has a need to be enhanced and protected. The whole process of enhancing and protecting this entity can be observed as a constant activity in the default mode network during the resting state of the brain. This activity can in turn feed and activate the left-brain interpreter again.

Excessive activity in default mode network has been correlated with depression. It has also been found that decreased activity in default mode network correlates with increased happiness.

Based my own experience and according to various studies done on mindfulness meditation, I can say mindfulness reduces the activity in default mode network and changes the perception of self. The practise of Buddhist mindfulness and contemplating on the nature of reality ultimately leads to removing the psychological boundaries of ‘me’ and the ‘world’. The effects of mindfulness in improving emotional regulation and changing the perspective of ‘self’ has been discussed in detailed in the papers ‘‘How Does Mindfulness Meditation Work? Proposing Mechanisms of Action From a Conceptual and Neural Perspective’’ and ‘Neuroscience of Mindfulness’.

Neural mechanisms of suffering

Dr. Rick Hanson, Ph.D, a clinical psychologist, has written a wonderful book called ‘Buddha’s Brain: The Practical Neuroscience of Happiness, Love & Wisdom’. In this book, he has attempted to bridge science with the traditional Buddhist teachings. He explains the neural mechanisms of suffering and explains how, by meditation, one can bring neuroplastic changes in the brain and end suffering.

So, what exactly happens when our brain perceives a threat to our self-image?. Our brain regards it as a danger and activates the amygdala. Here is how he describes it:

“Something happens. It might be a car suddenly cutting you off, a put-down from a coworker, or even just a worrisome thought. Social and emotional conditions can pack a wallop like physical ones since psychological pain draws on many of the same neural networks as physical pain (Eisenberger and Lieberman 2004); this is why getting rejected can feel as bad as a root canal. Even just anticipating a challenging event—such as giving a talk next week—can have as much impact as living through it for real. Whatever the source of the threat, the amygdala sounds the alarm, setting off several reactions: The thalamus—the relay station in the middle of your head—sends a “Wake up!” signal to your brain stem, which in turn releases stimulating norepinephrine throughout your brain. norepinephrine throughout your brain. The SNS sends signals to the major organs and muscle groups in your body, readying them for fighting or fleeing. The hypothalamus—the brain’s primary regulator of the endocrine system—prompts the pituitary gland to signal the adrenal glands to release the “stress hormones”epinephrine (adrenaline) and cortisol.

Within a second or two of the initial alarm, your brain is on red alert, your SNS is lit up like a Christmas tree, and stress hormones are washing through your blood. In other words, you’re at least a little upset. What’s going on in your body? Epinephrine increases your heart rate (so your heart can move more blood) and dilates your pupils (so your eyes gather more light). Norepinephrine shunts blood to large muscle groups. Meanwhile, the bronchioles of your lungs dilate for increased gas exchange—enabling you to hit harder or run faster. Cortisol suppresses the immune system to reduce inflammation from wounds. It also revs up stress reactions in two circular ways: First, it causes the brain stem to stimulate the amygdala further, which increases amygdala activation of the SNS/HPAA system—which produces more cortisol. Second, cortisol suppresses hippocampal activity (which normally inhibits the amygdala); this takes the brakes off the amygdala, leading to yet more cortisol. Reproduction is sidelined—no time for sex when you’re running for cover. The same for digestion: salivation decreases and peristalsis slows down, so your mouth feels dry and you become constipated. Your emotions intensify, organizing and mobilizing the whole brain for action. SNS/HPAA arousal stimulates the amygdala, which is hardwired to focus on negative information and react intensely to it. Consequently, feeling stressed sets you up for fear and anger. As limbic and endocrine activation increases, the relative strength of executive control from the PFC declines. It’s like being in a car with a runaway accelerator: the driver has less control over her vehicle. Further, the PFC is also affected by SNS/HPAA arousal, which pushes appraisals, attributions of others’ intentions, and priorities in a negative direction: now the driver of the careening car thinks everybody else is an idiot. For example, consider the difference between your take on a situation when you’re upset and your thoughts about it later when you’re calmer. In the harsh physical and social environments in which we evolved, this activation of multiple bodily systems helped our ancestors survive. But what’s the cost of this today, with the chronic low-grade stresses of modern life? “

This constant  ‘SNS/HPAA arousal’ (Sympathetic nervous system –  hypothalamic-pituitary-adrenocortical axis) when a threat is perceived for this ‘egoic self’ is the reason why we go through unnecessary stress and suffering. Practices like mindfulness shrinks amygdala and inhibits SNS/HPAA arousal. Many years of mindfulness practise combined with insights of reality produces neuroplastic changes in the brain which results in spiritual enlightenment.

In addition to this Rick also explains how a duality is created:

 

  • “The parietal lobes of the brain are located in the upper back of the head (a “lobe” is a rounded swelling of the cortex). For most people, the left lobe establishes that the body is distinct from the world, and the right lobe indicates where the body is compared to features in its environment. The result is an automatic, underlying assumption along the lines of I am separate and independent. Although this is true in some ways, in many important ways it is not.

 

  • Since we are each connected and interdependent with the world, our attempts to be separate and independent are regularly frustrated, which produces painful signals of disturbance and threat.”

Neural Correlates of Non-dual Awareness

Now, we are going to look at another paper called ‘’Neural correlates of nondual awareness in meditation‘, which talks about a nonconceptual nondual awareness (NDA) that abides, ordinarily unrecognized, in the background of all conscious experiencing.

The paper gives a detailed  description of the non-dual awareness:

“This background awareness appears in meditation to be unitary and unchanging—a cognizance that is in itself empty of content, yet clearly aware and blissful—whereas various sensory, affective, and cognitive contents, and the various states of arousal appear to it as dynamic processes or, as a well-known metaphor states, like images in a mirror.NDA is characterized, among others, by its reflexive property—it knows itself to be conscious without relying on subsequent moments of conceptual cognition. According to some traditions,our inability to ordinarily detect NDA is due to an obscuration of this reflexive property by mistaken cognitions arising from substrate consciousness.

Although NDA is experienced in meditation as a vivid presence of empty awareness that knows itself directly without mediation by conceptual thought, substrate consciousness is experienced as a pleasantly restful absorbed state, akin to deep sleep yet not entirely unconscious, which one knows retroactively. The question of what may be the relationship of NDA to subjectivity and a sense of self has been a matter of considerable debate among various Asian philosophies and is beyond the scope of this review.”

The result of the studies suggest that ‘Precuneus awareness network’ is responsible for the non-dual awareness:

“Although our previous study did not find statistically significant differences in connectivity of individual ROIs, the connectivity of the central precuneus ROI was marginally higher for the NDA condition. The above statement has led us to hypothesize that the central precuneus network might be significantly involved in NDA. Our interest in this region was furthered by participants’ reports of the presence of two particular features of NDA: reflexivity, traditionally described as awareness being aware of itself; and spatial extendedness, described as the sameness of space inside and outside of one’s body.

Preliminary data from this study indicate that NDA resulted in an increase in connectivity between the central precuneus and the dlPFC, accompanied by a decrease in connectivity between the central precuneus and the right angular gyrus (rAng), whereas the connectivity of the rAng to the right dlPFC and left dorso-medial prefrontal cortex increased, and the interhemispheric connectivity between the left and right dlPFC decreased.

Interestingly, no significant changes in connectivity have been observed between the central precuneus and the medial prefrontal cortex, and between the dorsal anterior cingulate (ACC) and other ROIs.”

Following are the interpretations made based on the observation:

    1. An increase in functional connectivity between the central precuneus and dlPFC could be indicative of a degree of unity of awareness 95 and related to the reflexivity of NDA, as information from the central precuneus is maintained online in working memory.
    2. The observed decrease in connectivity of the central precuneus to the right angular gyrus may be contributing to experiences of spatial extendedness, as the two areas are together involved in integrating spatial reference frames.
    3. The absence of significant changes in functional connectivity between the central precuneus and the areas of the medial prefrontal cortex may indicate that during NDA, even with minimized phenomenal content, there is no active suppression of self-referential processing such as that seen in FA or OM meditations.
    4. The absence of significant changes in connectivity of the dorsal anterior cingulate cortex (ACC) may be indicative of the more effortless, less cognitively controlled nature of NDA meditation.

A Contemporary Theory of Awakening – by Richard Boyle

Another noteworthy scientist who did research on spiritual enlightenment is Dr.Richard Boyle. He has worked as a Senior Research Scientist at the Institute for Social Research, University of New Mexico. He has written a book called ‘Realizing Awakened Consciousness – Interviews with Buddhist Teachers and a New Perspective on the Mind’ which has a collection of interviews with eleven prominent Western Buddhist teachers (Shinzen Young, John Tarrant, Ken McLeod, Ajahn Amaro, Martine Batchelor, Shaila Catherine, Gil Fronsdal, Stephen Batchelor, Pat Enkyo O’Hara, Bernie Glassman, and Joseph Goldstein) and one scientist (James Austin) who have experienced awakening.

He has published a paper called ‘Cracking the Buddhist Code:A Contemporary Theory of Awakening’ in  Journal of Consciousness Studies. Here is the abstract of the paper, which makes a lot of sense:

“The theory proposes that what Buddhists and others have called awakening is the same thing as “pure perceptual experience,” defined as the awareness our perceptual systems would present to us if they acted on their own, with no interference from conceptual systems. Two forms of interference are particularly apt to interfere with pure perceptual experience: uncontrolled inner speech (wandering thoughts, monkey mind) and distortion of perception to fit reified conceptual structures. Monkey mind has been shown to be caused by hyper-activity in the Default Mode Network (DMN) of the brain, which happens whenever nothing else demands our attention. Reification occurs, especially, in three kinds of symbolic structures, all of which we acquire as part of the culture we are born into:

  1. Scripts, which describe situations and events and prescribe appropriate behavior.
  2. Conceptual systems – theories, belief systems, social reality, world views, theologies and ideologies, etc.
  3. The underlying construct of four dimensional spacetime, in which we think we live.

The fact that predispositions toward uncontrolled DMN activity and reification of conceptual structures are essentially universal among humans means (at least within the realm of science) that they must have evolutionary roots. However, some people have and do overcome these two biological predispositions by engaging in such special practices as meditation and forms of inquiry. The theory seeks to specify how all this works in more detail and a way that allows the predictions to be studied.”

Persistent Non-Symbolic Experiences

Dr. Jeffery A. Martin is a founder of the Transformative Technology space, serial entrepreneur and social scientist who researches personal transformation and the states of greatest human well-being. He spent the last 10 years conducting the largest international study on persistent non-symbolic experience (PNSE), which includes the types of consciousness commonly known as: enlightenment, nonduality, the peace that passeth understanding, unitive experience, and hundreds of others. More recently, he has used this research to make systems available to help people obtain profound psychological benefits in a rapid, secular, reliable, and safe way.

He has done research on over 1200 participants (who claim to be enlightened) all over the world and he has made many publications. He has documented various traits that he has observed in enlightened people in his paper ‘Clusters of Individual Experiences form a Continuum of Persistent Non-Symbolic Experiences in Adults’ . The list of his publications can be read at his website.

Other scientists who were involved

Apart from the ones that I have mentioned, there are many other scientists who have done research on this topic and have written books about it.

Arthur J. Deikman, who was a clinical professor of psychiatry at the University of California did a lot of research on the subject and coined a term called ‘Mystical psychosis’.This term is used to to characterize first-person accounts of psychotic experiences that are strikingly similar to reports of mystical experiences. When Arthur himself went through a mystical experience, he became more interested in this subject. You can find many of his articles on his website. One particular article ‘Awareness’ explains the non-dual awareness in detail.

Modern scientists like Culadasa and Sam Harris are also worth mentioning. They have written books about meditations and spiritual awakenings. Abraham Moslow’s theory of self-actualization is the earliest description in psychology of the ultimate human potential, which is very close to self-realization. Willaim James, an early psychologist has studied various spiritual experiences and has written a book about it.

Conclusion

What do we get from all these studies which have been conducted? They all offer various clues on the direction that we need to go, in order to do more research. While we can’t derive strong conclusions based on the existing evidence, they make it very easy to narrow down to the exact neural correlates involved in spiritual enlightenment.

Many neuroscientists are interested in researching spiritual awakenings, as they now know that it is about something that definitely exists as a possibility for human beings to end their suffering and live a more peaceful life. As Neuroscience grows, we will soon have many ways to study the brain and understand exactly how a spiritual process works.

Science and Reincarnation

Does reincarnation exist? Well, there has been a lot of scientific research done on the topic of reincarnation and many psychologists are still doing experiments on this topic. Psychiatrist Ian Pretyman Stevenson was well known for his research as he traveled extensively over a period of forty years, investigating three thousand cases of children around the world who claimed to remember past lives.  He wrote many books on this as well. However, skeptics complained about a lot of issues in his experiments. But Ian Stevenson’s research about reincarnation is very popular in the scientific world and can definitely serve as a guide to do more experiments in the future.

Jim Tucker is another important psychiatrist who has done many experiments and studies. The reason I consider him as important is because of an unbelievable story of a boy named ‘James Leininger ‘.  Here is an excerpt of an interview between Jim Tucker and Rachel Martin (http://www.npr.org):

MARTIN: Let’s talk about a few of those. You mentioned your recent book. It’s called “Return To Life.” And you chronicle the stories of many children, including one that got a lot of national attention. It was the story of James Leininger. He was a boy who remembered being a World War II fighter pilot. Can you walk us through that case?

TUCKER: Sure. So James is the son of a Christian couple in Louisiana. And when he was little, he loved his toy planes. But also around the time of his second birthday, started having horrific nightmares four or five times a week – of being a plane crash. And then during the day, he talked about this plane crash and said that he had been a pilot, and that he had flown off of a boat. And his dad asked him the name of it, and he said Natoma. And he said he had been shot down by the Japanese; that he had been killed at Iwo Jima; and that he had a friend on the boat named Jack Larsen. Well, it turns out that there was an aircraft carrier called the USS Natoma Bay that was stationed in the Pacific during World War II. In fact, it was involved in Iwo Jima. And it lost one pilot there, a young man named James Huston. James Huston’s plane crashed exactly the way that James Leininger had described – hit in the engine, exploding into fire, crashing into the water and quickly sinking. And when that happened, the pilot of the plane next to his was named Jack Larsen.

MARTIN: And how old was James when he was making these claims?

TUCKER: Well, it started when he was 2 – and a very young 2.

MARTIN: That’s amazing.

TUCKER: Like with most of these cases, it faded away by the time he was 5 or 6 or 7, which is typical. But it was certainly there, quite strong, for some time.

MARTIN: And how do you know that these kids aren’t echoing things they have heard their parents talk about or making up stories, using their imagination, articulating dreams they may have had?

TUCKER: Yeah. Well, certainly with the imagination part – if we had never been able to verify that what the child said matched somebody who died, then you could certainly just mark it down as being fantasy. But in cases like James’, the previous person, James Huston, was so obscure – I mean, he was a pilot who was killed 50 years before; and he was from Pennsylvania, and James was in Louisiana – I mean, it seems absolutely impossible that he could have somehow gained this information as a 2-year-old through some sort of normal means. In fact, it took his dad a couple of years – well, really more than a couple of years; three or four years – to be able to track it all down and see that in fact, that what James was saying all did fit for this pilot who was killed.

(Read the entire interview here: http://www.npr.org/2014/01/05/259886077/searching-for-science-behind-reincarnation )

Jim Tucker thinks that consciousness would not necessarily be dependent on a physical brain in order to survive, and could continue after the physical brain and after the body dies.

Max Planck, Nobel Prize-winning German physicist and the father of quantum theory has stated “I regard consciousness as fundamental. I regard matter as derivative from consciousness. We cannot get behind consciousness. Everything that we talk about, everything that we regard as existing, postulates consciousness.” Whatever Max Planck said is exactly what has been taught by various orthodox schools of ancient India for thousands of years. Even though it has not been proved scientifically, such an opinion from a Nobel Prize winning Quantum physicist certainly indicates that science is not far away from discovering this as a fact.

Since there are always skeptics who come up with arguments to prove that the findings of such experiments about reincarnation are not valid due to some flaws in the experiments, I searched for any such information regarding the case of James Leininger. I couldn’t find much. However, I found this blog article very interesting.

Here is another interesting account of reincarnation:  https://exemplore.com/paranormal/The-Reincarnation-Of-Anne-Frank-Barbro-Karlen-The-Amazing-Story-Of-Past-Life-Memories

I have heard many Yogis saying that everybody retains the memories of their previous lives until they are 2-3 years old. Then they are gradually forgotten once the memories of the current birth begin to add up. So, it is not surprising that all these scientists have documented about the cases of young children who have remembered their past lives.

I believe that the answer to the question of reincarnation lies in the field of Quantum Physics. May be in the next 50 years, scientists will finally discover a way to unite science and the metaphysical concepts of ancient religions.
