I was always very skeptical about that. But now in mot so sure.
I have read many books on the subject and I have a fair idea about how to do it and although I was a skeptic I had never actually tried it. So last night I did. Now supposedly when you are rising out of your body you vibrate vigurously. I was on the tip of sleep and I felt tingling all over my body and I woke up suddenly!
Im not so sure now but I advise anybody to try it!
