Query: My first book into out of body

Short and sweet! This was my first book concerning this subject. By simply opening one's mind to the subject it usually induces itself. For instance, I have spoken about my experiences to personal friends and family, and they have had an OBE shortly there after. This book definitely calmed many of my fears, and helped me become better at OBE's. This book is a must for anyone interested in OBE's. If you are a skeptic, simply experiment for yourself, this book yields a wealth of info for your experimenting pleasure. I would highly recommend an open mind and Robert Monroe's 3 books on the subject. Also check out the Robert Monroe institute. Good luck!
