To learn more about regression, Dr. Weiss says he tapped into his own past lives with the help of his wife Carol. During his first session, he says he regressed back to a time when he was a Babylonian priest. "I kept hearing the word 'ziggurat' in my head, and I didn't know that word," he says. "I had a lot of power and spiritual abilities, but I was misusing the position for greed and more power."
In another life, Dr. Weiss says he was a Catholic priest in Scotland during the Middle Ages. "[I was] killed in the inquisition for teaching about reincarnation and other forbidden subjects," he says. "So I must have gotten over my fear somewhere along the way."
