Nirgunache Bheti & Tatvamasi are the biographical films based on brief life history as well as the core teachings of Shree Nisargadatta … The teaching of Non-Duality… Advaita.
As a matter of fact very little data or information about Nisargadatta was available anywhere. He would rarely speak about the personal events & aspects, yet some of the events are taken from the experiences shared by his closest disciples/students as well as from a few books available on Him.
