Query: This book is simply extraordinary.

This book is simply extraordinary. It not only presents the kabbalah from its classical viewpoint, but does so with intelligence and lucidity. One of the most fascinating aspects of this book is the correlations it makes between the kabbalah and physics. It truly makes you wonder about God and Creation. I can only say that it helped transform my life and my views of the cosmos and my own existence. If you ever wanted proof of the existence of a Supreme Intelligence behind creation, look no further. This book is IT. I think everyone should read it, whether or not you are a believer.
