it is excellent book telling us about various aspects of philosophy. the interaction between chitralekha and kumargiri is very important and i hope it is the soul of the book. i strongly recommend this book.
I've read books by Dan Brown, J.K. Rowling, Atul Gawande, Chetan Bhagat etc. These were great too but this book, according to me, compares to Shrimad Bhagawad Gita (yes I've read its thick descripted versions also). While Gita was a theory, this book is a practical manual. Its so deep and meaningful, I wonder how in the first place author managed to write it down. Hats off to him. A must read in my opinion!
