I found a book that is quite similar in style/substance to "Autobiography of a Yogi"
The book is called "Third Eye and Kundalini"
I bet a lot of you are going to be excited about it.
I found it in the library, but did not bring it home because of the little bit of Sathya Sai Baba stuff in it (controversial guru). But if you ignore the bit of it it has, it might be the authentic journal of a real yogi. I flipped through it, and it seemed real interesting.
Author Goel, B. S. (Bhim Sain), 1935- Imprint Kurukshetra, Haryana, India : Third Eye Foundation of India, 1985-1986. Title Third eye and kundalini, and experimental account of journey from dust to divinity.
