In the beginning I was not able comprehend the book as I thought its language was very hard to understand, I was bit mad, thinking a spiritual leader like him should have written the book in simple language for common people like me. So when I first try to read it, I didn't understand a thing and instantaneously lost interest from it but I knew the importance of reading it and It was my desire to complete the book so I left the book, promising that I will come back later when Ill have enough knowledge to able to grasp it which I knew will be after a long period. Not after long I applied for yoga course since I am into it, not perticular kriya yoga but surykriya and just practicing it for 7 days I come across this book again, I don't know what came over me and I gave one more try not because I wanted to complete it and gain knowledge but just to pass time doing something, but this time I was able to understand the book with not much hassle, yes, though still in the beginning I struggle but my determination to understand won over me and with every passing page it become simple, I felt like yogananda ji was talking to me, telling me his story with his sweet melodious voice. I haven't complete the book yet, midway through it. But I love every single word of it. Especially the interaction between him and Sri Yukteshwar giri guruji is delightful, The immense love yogananda ji have for his guru can be experience as you read through the words on the pages of this book, its very astonishing to feel it. As far reading this book has been a pleasant and calm experience and you should have it to.
