I've read numerous books on Psychology, Philosophy, Leadership, Self help/development and other all-time best sellers. Somehow, I was not satisfied. Then, I happened to read a couple of books on Vedic knowledge. This book is a must-read if you are interested in the ultimate knowledge. I'm sure you will agree that this book will bring a very positive perspective about life and will benefit you much. For me, It's been a life changing experience. I'm still immerested in the greatness of this book. It's a section on western phiolospheres (Freud, Greek philosopher) which is very good. Now, I don't need to look for anymore best sellers. I'm happy.
The Science of Self-Realization (by the same author) is also equally good. My suggestion is pick either of these books. If you like the first one, you can get the 2nd one.
