Robert Monroe on Out-of-body experience

“Early in the experimentation, a side effect began to manifest itself. It was not an out-of-body activity as such, but took place in states of deep relaxation prior to any separation. It is evidently called in the trade "precognition." As I was lying down, my mind stilled and body relaxed, without my volition, the "vision" would occur.”

“According to the literature of the psychic underground, the religious-mystical history of man constantly makes reference to this Second Body. Long before Christianity and the Bible appeared, cultures in Egypt, India, and China, to name a few, held the Second Body idea as standard operating procedure. Historians have found these references again and again, but evidently consigned them to the mythology of the times. If one reads the Bible from this point of view, the belief is confirmed many times in both the Old and New Testaments. In the Catholic Church are found consistent reports of saints and other religious figures having such experiences, some of them willfully. Even in Protestantism, devout followers have reported the out-of-body experience during some form of religious ecstasy. In the Orient, the concept of a Second Body has long held a natural and accepted position of reality.”
