In this short article, Sadhguru looks at how the most dominant factor of his life has been his Guru.
Sadhguru: The most dominant factor of my life has been my Guru, and nothing else. Even today, in my mind, or rather literally in every crevice of my body, in every pulsation of my system, and in my very energy, it is his presence that is the most dominant within me. To keep it this way has been easy for me because I do not have a mind of my own. Probably because of this, just about everything in me reverberates in a way that is far beyond me, far bigger than me.
I did not see my Guru as a man who touched me, though his touch brought me to the highest level of experience, and a revelation of life and beyond. The old mental structure within me somewhere would not accept a human being as a Guru, because it was said that unless it comes from Adiyogi, unless it comes from Shiva himself, it is not real. So the compassion of my Master made him turn himself into the form of Shiva.
I do not know if this was his act that he turned himself into this form, or if that is how he really was at that time. But this experience has left me in a place where ever since, I do not have to make any attempt to know anything. Whatever I need to know, He [Guru] and He [Shiva] are there, all the time.
