Edgar became known as The Sleeping Prophet due to his ability to go into a self-induced hypnotic trance. He would lay on his couch, close his eyes, relax, meditate and go into a trance (now known as the Alpha state of mind). He said this state allowed him to connect his mind with all space and time.
While in this trance Edgar’s client, who would be sitting nearby, would ask questions on health, romance, what life is all about, pretty much anything that the client wanted deep and meaningful answers about. This process became known as a psychic reading.
