I almost can't believe that this book is not listed here!!! This book was written by the guy who taught Kriya Yoga to Mahatma Ghandi! He is also the guy who originally brought Yoga to the west. It's a must read. Paramahansa tells his whole life story, which is all factual. He died a saint, proven by his California coroner's record which stated that neither rigormortis nor decay of any kind was evident on his body even 26 days after death! He was put on India's national postage stamp to officialize his status as a national hero. Oh, and though he became a Swami and mastered Kriya Yoga, he openly admitted that he knew that Christ was the supreme being. It was read by my godmother 25 years ago and also instrumental in my path. I repeat, it's a must read, especially for people struggling to reconcile eastern and western points of view like I was.
