(Update: 11/06/2018:
Due to a lot of misunderstandings, let me make something very clear. If you call the Absolute, the Brahman and the inner light of all sentient beings as Shiva and if you refer to that Absolute as the first guru, I don’t have any disagreements at all. In fact, I insist people follow this inner light.
But Sadhguru’s version of Adiyogi is about a human being who lived 15,000 years ago, who really married a human woman called Parvathi and who gave birth to two yogis called Skanda and Ganesha.
In other words, he implies that all Puranic stories are real and not metaphorical. But his story of Adiyogi actually matches a folk story of Nandinatha which is prevalent in Kashmir Shaivism. Before you comment, I request the readers to fully understand the intention of the article.
For more details and clarity, don’t fail to read the above mentioned Quora answer and also this one: What is the derivation of the word ‘Shiva’?. In this Quora answer, I have clearly explained the derivation of the word Shiva. Also, read this post to understand the metaphorical meaning of Ganesha and Skanda: A Shamatha Meditation Based on Symbolism, Visualization, Mnemonics and Classical Conditioning)
Recently, a 112-foot Adiyogi statue was unveiled in Isha Foundation, Coimbatore by Prime Minister Narendra Modi. The beautiful statue was designed by Sadhguru Jaggi Vasudev as a credit to the first yogi and as an inspiration for the world. But who is the actual first yogi revered by yogic tradition? Was it really the mystical Lord Shiva or someone else? Sadly, the original Adi yogi has been forgotten and has been replaced by a carelessly spun story by Sadhguru Jaggi Vasudev.

Let me first quote the story as it is narrated by Sadhguru.
Story of AdiYogi as narrated by Sadhguru
“When we say “Shiva,” there are two fundamental aspects that we are referring to. The word “Shiva” literally means “that which is not.” On another level, when we say “Shiva,” we are referring to a certain yogi, the Adiyogi or the first yogi, and also the Adi Guru, the first Guru, who is the basis of what we know as the yogic science today.
In the yogic culture, Shiva is not seen as a God. He was a being who walked this land and lived in the Himalayan region. As the very source of the yogic traditions, his contribution in the making of human consciousness is too phenomenal to be ignored. This predates all religion.
Over 15,000 years ago, Adiyogi appeared in the upper regions of the Himalayas. No one knew where he came from or what his origins were. He just came and went into intense ecstatic dance upon the mountains.
People saw that he was experiencing something that nobody had known before, something that they were unable to fathom. So they gathered around him wanting to know what it was. But no one had the courage to go near him because he was so intense, like a blazing flame of fire. So they waited, hoping something would happen. Some people waited for months and left and Only seven hardcore seekers stuck on. These seven were insistent that they must learn from him, but Shiva ignored them. They pleaded and begged him, “Please, we want to know what you know.”
At last after 84 years of intense sadhana,he decided to become a Guru. On a full moon day which is known as Guru Pournami because the Adiyogi transformed himself into the Adi Guru – the first Guru was born on that day. He took the seven disciples to Kantisarovar and started a systematic exposition of yoga in a scientific manner. He began propounding the whole mechanics of life to these seven people, not intellectually as a philosophy, but experientially. He explored every nut and bolt of creation with them. He brought forth yoga as a technology with which every human being can evolve himself.
The transmission went on for a long period of time. After many years, when it was complete and had produced seven fully enlightened beings, who are today celebrated as the Sapta Rishis, Adiyogi sent each one of them to different parts of the world. One went to Central Asia. Another went to North Africa and the Middle East, where certain schools exist even today. Another went to South America, and that is one culture that imbibed it in a deep way and made something big out of it. One went to East Asia.
One stayed right there with Adiyogi. Another one came to the lower regions of the Himalayas and started what is known as Kashmiri Shaivism. Another one went south into the Indian Peninsula. This one is very important for us because he is Agastya Muni. Of the seven Sapta Rishis, Agastya Muni has been the most effective in terms of bringing the spiritual process into practical life, not as a teaching, philosophy or a practice, but as life itself. It is the benefit of what he did that the Indian people are still enjoying because he produced hundreds of yogis who were like fireballs.” and it goes on.”
First, it looks like Sadhguru has mixed two different stories and made them into one story. I don’t mean that Sadhguru would have intentionally done that. Regardless of whether someone is enlightened or not, human memory has its limitations. Sadhguru probably heard these stories a long time ago and due to memory errors, he might have made the two stories into one, which narrates something that never happened. I don’t blame Sadhguru, but the blind followers who simply take whatever Sadhguru says as correct.
I think it is important to make a few things clear. Let me first discuss who this Shiva is and a story from mythology that talks about Dakshinamurthy. Then I will talk about the real Adi yogi, who initiated 8 sages and sent them to different parts of the world.
Who is Shiva?
First, the word ‘Shiva’ doesn’t mean ‘that which is not’, as said by Sadhguru. I have no idea how he came up with such a meaning. The word ‘Shiva’ means ‘auspicious’, which has always been used as an adjective in Vedas. The word has been used for many deities, not just Rudra, the earliest form of Lord Shiva that we know today. It was just a word used to honour someone. Slowly, the word ‘Shiva’ got associated with the Vedic deity Rudra.
Second, mythology is not history. The stories in mythology might have been created for various reasons: to convey deep mystic teachings in the form of a story, to help people to develop devotion for a personified form of the ultimate truth as an aid towards self-realization, to entertain people etc. A puranic story always has multiple contradictory versions, each of them created by people to glorify their own favourite personal God.
Sadhguru has many times indicated that this Adiyogi is the same as Dakshinamoorthy. But the story of Dakshinamoorthy and the story of the Adiyogi who sent 8 rishis to different parts of the world are two entirely different stories.
Let me narrate a puranic story. When Lord Brahma was doing his work of creation, he created many sons from different parts of his body. Four of his sons named Sanaka, Sanatana, Sanandana and Sanatkumara were born from the mind of Brahma. These four people became Brahmacharis against the wish of their father. It is also said that Brahma became very angry because of that, and out of anger Rudra, the earliest form of Shiva was born.
But in Shaivite traditions, it is said that these four people approached Shiva who then assumed the form of Dakshinamoorthy to teach them. He taught them about Self-realization using chin mudra that symbolically shows how a person realizes the ultimate truth. That was all his teaching! According to the story, he just taught the essence of all the scriptures by a small gesture. Note that this applies to all traditions, not just Yoga. Most of the Indian schools of thought like Advaita, Yoga, and Samkya have the same essence even though they use different terminologies.
There are different stories associated with these four kumaras. Some of them are contradictory. Each purana has its own version. So, it is very clear that Dakshinamoorthy is a pure form created for devotion and sadhana, not a historical being who walked on the earth. And Dakshninamoorthy was not shown as teaching traditional Yoga at all. He is clearly not the Adiyogi of the yogic tradition. But this is not to deny the significance of Dakshinamoorthy in anyway. He is a great symbolic representation of enlightenment.
Who is the real Adiyogi?
During 200 BC or 300 BC, a great yogi called Nandhi natha lived in mount Kailash. He was a real human being who walked this planet and was the guru of the great Patanjali. He initiated 8 disciples (Sanatkumar, Sanakar, Sanadanar, Sananthanar, Shivayogamuni, Patanjali, Vyaghrapada, and Tirumular) and sent them to various parts of the world including central Asia to spread Advaita Shaivism. The whole Yogic tradition goes back to Patanjali whose Guru was Nandi natha. Nandi Natha also composed a poem with 26 verses called Nandikeshvara Kashika.
Even today, the Nandhi natha yogic tradition regards Nandi natha as the Adiyogi. A school of this lineage called Adi Natha does regard Shiva as the first yogi, but that was just a title given to Nandinatha, since Shiva means ‘auspicious’.
Tirumular, a well known Tamil saint and the disciple of Nandhinatha was actually the one sent by Adi yogi to south India to spread this school (not Agasthiya). Shiva sending sage Agasthiya to South India to balance the earth was just another puranic story and even that story doesn’t say that he was sent to south India to teach Yoga, as Sadhguru narrates.(Again, this is not to deny the significance of Agasthiya; He was a great Siddha who made great contribution to the world).
Vigyan Bhairav Tantra – 112 techniques for Yoga
Sadhguru also says that Adiyogi statue is 112 feet high and this is to represent the 112 techniques given by Lord Shiva. These 112 techniques are from Vigyan Bhairav Tantra, which is claimed to be a part of ancient Kashmir Shaivaite text called Rudrayamala. It was composed by an unknown author sometime around 8th century AD as a form of imaginary conversation between Shiva and Shakthi.
So, this Vigyan Bhairav Tantra is in no way related to the Adiyogi Nandhi natha or a historical man called Shiva. The whole text of Vigyan Bhairav Tantra was actually popularized by Osho all over the world. Vigyan Bhairav Tantra is a very rare text which was translated to English by Paul Reps based on the commentary given by Swami Lakshman Joo Raina, a self-realized mystic of Kashmir Shaivism. The translation of Paul Reps was used by Osho to give his own commentaries.
The credit of popularizing Vigyan Bhairav Tantra goes to these three people: Lakshman Joo, Paul Reps and Osho. Without them, not many people would have known about this valuable text.
As I already mentioned in my previous article ‘The Journey of a Seeker’, Sadhguru uses so many anecdotes, information, views and ideas given by Osho but never gives him credit. Osho was an honest and courageous man who created a great worldwide awareness about self-realization. He was the first man to popularize the fact that there is nothing wrong for a self-realized man to live a normal life with all the luxuries of the world. If Osho didn’t have the courage to own 92 Rolls Royces and still claim enlightenment, we wouldn’t be accepting Sadhguru owning a helicopter or playing golf. It is easier to accept Sadhguru now because we have already seen Osho like this. Osho did all the groundwork but the poor man doesn’t get the credit.
The Adiyogi statue looks beautiful, there is no question. But he didn’t build this statue to give credit for whoever the adiyogi was. It is simply a statue of Lord Shiva built to attract crowds and tourists. If Sadhguru is the kind of man who gives credit to people, then he would have given credit to Nandhi Natha (the actual Adi yogi) and Osho already.
