Autobiography of a Yogi, by Parmahansa Yogananda, is one of those books that made a deep impact in my life. I believe that the very purpose of life is to be happy. And this book explains that happiness is not about materialistic joys but is a state of being. And it all starts with listening to yourself. The magic of the book compels you to internalise what it teaches. Yogananda has not described the path to reach God but the desire to attain a higher state of spiritual being. This desire is the first step to reach Him. The book is a good guide to those who have a higher goal in life.
