Purely true. Filled with examples and techniques that is perfect for people living in India. If one wants to go in depths of spiritual world, one should try this book right now. The book is different from other religious-spiritual books because it doesn't deceives you. Although he has mentioned clear techniques, but it can be tricky to understand where he is pointing. One should read it with patience & clearity. It's straight written, and one can practice it's principle everyday.
I find it deeply satisfying because it has full filled my all answers.
Thank you kamal.
