I was interested for some months in Astral Projection (since I heard about it), so I decided to give it a try by buying this "practical" book. I tried, and I tried, and I tried, but nothing happened, besides some positive effects on my life, which were results of the chakra technique.
The bad thing about this book is that it is NOT practical. Noone can do the painstaking and time-consuming techniques it describes without getting either frustrated or bored. There are so many unnecessary and goal-distracting little things it tells you, that it could get you to even hate Astral Projection (AP), which is the contrary to the writer's intentions!
My advice to the potential Astral Traveller (anyone can do AP, don't be afraid to try) is the following: Don't read this book. Or read it but don't take it too seriously. I acknowledge the effort of the writer but unfortunately this book is goal-distracting and it provokes unnecessary fears, prejudices and drawbacks. You wanna do AP? Search the web with many different search engines for "astral projection" or "out of body experience" and read. Read A LOT. Read EVERYTHING. In the end, you'll understand what AP is, and figure out what's the best technique for you.
I give it 3 stars for some good info contained, and for the chakra technique. Nothing more in this book is useful.
I've been reading these negative reviews and find that they are based primarily on a fundamental lack of knowledge and in a couple cases easy solutions to the complexity of this kind of work. One reviewer claims that this book is too "occultish". That's laughable, becuause not many things are more "occult" that trying to force your spirit from your body with the intentions on traveling to other dimensions of reality.
Having said this, the book is challenging because it actually asks something of the reader......dedication and commitment to the process. These authors are practicing metaphysicians/magicians for many years and are the head of a magickal order based in England called Aurum Solis (Denning recently passed away).
There is a lot of experience between these pages and it can work for you if you work with the techniques within.
