This is a "Hard to put down" book. Once you begin reading you are tempted to "rush through" to get to the end. I HIGHLY suggest following the recommendations and doing the lessons as they come to you. Even though I am only halfway through I have discovered that my skeptical mind is being set free. As a VERY SKEPTICAL person in this area, I have been very surprised at the results. I am also reading Out of Body Experiences "how to have them and what to expect" by Robert Peterson as well which I recommend a read before you go to sleep as then this puts into your subconscious the real possibilities.
As for the many books I have read on the subject as part of my Psychology studies for school, this is one of the best, no...this is the BEST book on the subject and the How To is outstanding.
From all the books I have on the subject, this is the first that can be used as training material. It's comprehensive, easy to use and read, and the reader isn't bored to death with lenghty oppinions by the authors. They present everything that you need to know in an easy and fun training program.
