I have read hundreds of books on self-development, psychology and success but never found anything complete, anything that would answer my questions, until i found this book. It combines science and spirituality into one coherent framework and gives a whole new perspective on how to think of human motivation. I admit it requires and open mind to thoroughly understand the concepts written in this book but it is worth to give it a go in my opinion.
