In my post https://vedanta.manishverma.site/living-without-eating/ I had mentioned about the book “Autobiography of a Yogi” written by Shri Paramhansa Yogananda. The contents of the original edition of this book are available in .pdf form at this link. This eBook should be useful to a spiritual seeker or to someone facing questions like “Who am I?” or “What is the purpose of life?”.
