Edgar Cayce is the most documented American mystic. I have found answers to just about any health, life, and spiritual issues from the readings that came from this mysterious man ... including how to eliminate acne! The information works! This book is thick... a very good buy for the amount of information provided here. If you don't know much about Cayce, read "There is a River" from cover to cover, and read it with an open mind. Don't ask how he got that way... just like we don't ask how Jesus got that way. According to Cayce, (and even Jesus), we are all inherently 'this' way... (remember Jesus' statement "greater than these things shall you do...").
