The Nisargadatta Gita
The Nisargadatta Gita by Pradeep Apte. From the intro:
I came across a book ‘I Am That’ based on the talks of Sri Nisargadatta Maharaj. As I began going through it, I just couldn’t put it down, ‘This is dynamite!’ that’s the immediate feeling I had. I Then began preparing the text of ‘The Nisargadatta Gita’. In my life, so far, I had never met a living Guru, is my mere reading or studying of books of the teachings of all these great men of no avail? This last doubt was removed while I was editing the script of ‘I am Unborn’ where Sri Nisargadatta Maharaj answered this very question:
V: Do books replace a Guru?
M: Yes, books can replace a Guru. At one stage you yourself become a Guru;then you find out that books are of no use anymore. The Guru is one, who knows the beginning, continuity and the end of his life and understands the mind on which the environment has so much impact.( Page, 89, I am Unborn).
This answer came as a big relief and will also come to many like me who have never come across a living Guru in their life.
