Civ, I’m not so quick to dismiss Edgar Cayce as a scam. From everything that is known, and it has been heavily researched & documented, he was a decent and honest Christian gentleman, who never made money from his work. IMO he was a truly gifted psychic. His medical diagnoses and remedies are well documented, and still used today.
Have you read the books?
I’ve got a few of ‘em, the two I know for sure are the Jess Stearn book you mentioned (read that one the first time when I was in high school; a classmate had told me about Edgar Cayce and his supposed trance reading that told of the Atlantean use of a laser, before anyone had discovered that in the 20th c), and of the Cayce products, “Edgar Cayce on Atlantis” (how could I not have that one, since my nick’ is “SunkenCiv”?!?). Thanks to Jess Stearn, I also tracked down Taylor Caldwell’s “Romance of Atlantis”, which really sucked, and I think I had a Cayce remedies book, or maybe it was a cookbook. Wish the guy had lived in the microwave oven era, I’d be the healthiest person in town.
