Basic Fundamentals of Astral Projection
Format: Paperback
This book is full of great information about Astral Projection that is presented in a straightforward manner. I have read many books and articles about this subject over the past 10 years. Many are full of scraps of insight that are glued together with abundant amounts of repetition and babble. Mr. Sylvan Muldoon, like many of the great occultists from the early 20th century, has created a work that will refresh the weary, "would-be" traveler by keeping his explanations short and concise. His theory on the astral body being ruled by the subconscious conveys why auto-suggestion is extremely important when attempting separation. He provides the traditional method of maintaining the hypnagogic state via the raised forearm of which Robert Monroe echoes in his own exercises 40 years later. His "Dream True" method is unique to any of the techniques that I have read about in the past. I cannot recommend this book enough for anyone who is attempting the art of Astral Projection.

Good book, quite through
This was quite an in depth analysis on the subject which the author writes from his own experiences, and it seems quite obvious that he is not making any of it up. His explanations can be tedious at times, but this is in an effort to present the information as scientifically as possible, trying to answer any and all doubts and questions that would arise to the skeptical minded person. If you are interested in astral projection, I have never read a more revealing book on the subject.

Astral Projection From A Century Ago
Format: Kindle
This book is roughly a century old. With that comes a slightly different language but not one too difficult to follow. Some of the things that stuck out for me were: * The astral cable or “silver cord.” * The subjects of possession and the demonic. * The detailed suggestions for astral projection. This book could have used some editing ( there is the occasional “I” out of place) in spots but it remains very readable and helpful for understanding what astral projection is and different facets of it.

Marvelous!
This a Must Read for all OBE students and explorers. The kind of book that you can't let go of once you begin reading. The detail explanation and the descriptions are astonishing. I am amazed! It gave me a renewed interest in this discipline and I understood things that I'd given up on. What a fresh breath from a century ago... Thank you, Mr. Muldoon. I am at a loss for words to express my gratitude.

THE VERY BEST BOOK EVER WRITTEN ABOUT THE PROJECTION OF THE ASTRAL BODY!
Format: Paperback
In my opinion, Sylvan Muldoon's book continues after many decades to be the most inspiring and well written and meaningful book ever written on the out of body experience! I always suggest that anybody interested in the subject should always read this classic as being a truly honest and sincere, knowledgable guide written by the person many consider, The Father of Astral Projection.
