I have personally read this book when I was in college. I love yoga very much and so I ook this book from shop and I found it very interesting. The information given in the book is acually an experience of a yogi Yogananda mentioning his lifelong true journey through his lifetime. The miracles mentioned in the book are really wonderfull which a normal person cant believe but still they are amazing. I think every yoga lovers should read this book to achieve success in yoga in their life.
