Update (15/12 /2017) :
This is an old post. I don’t endorse or recommend to buy linga bhairavi gudi or Dhyanalinga yantra anymore… All you can get is a devotional feel when you have it at home but you can get the same feel even with a stone idol. I wouldn’t recommend anyone to waste their money on this (When I bought it, lingabhairavi gudi was Rs.23,000 and Dhyanalinga yantra was about Rs.11,000). There is no special energy or power that you can feel with it; if you think you do, it is just a placebo.

I got my Linga Bhairavi gudi in February 2016 from Isha Yoga Center. Ever since I got it, she is decorating my house with her wonderful presence. I dont feel like I have just an Idol. It feels like I am inside a temple, when I light lamps for her and sit in her presence.
I came to know about Isha during a satsang in Marina Beach in 2004. I completed the basic Isha Yoga program with Shambhavi Mahamudra practice and Bhava Spandana 12 years ago. I lived in Coimbatore for three years and have gone to the ashram about 30-40 times. To take a dip in theerthakund and to get immersed in the powerful presence of Dhyanalinga and Linga Bhairavi is a wonderful experience. I also climbed up the Velliangiri hills once. Here is my complete story: The Journey of a Seeker – My Story
But after getting Dhayanalinga yantra and Linga Bhairavi gudi, the same powerful presence filled my home. Having the yantra and gudi is like having two antennas to grasp and repeat the signals of the divine inside my home. It is like a range extender if I compare Isha to wifi.
