I like buying Cayce books but I'm skeptical. His son died I read recently when quite young. Also, it seems that most of his clients were told they were "royalty" or "walked with Jesus" in previous lives. I can't find any past life regressions where the client was told he or she was an ordinary person.
His errors don't bother me; all psychics make mistakes. But it bothers me when I keep reading that this or that client was a friend of Jesus, etc. His hospital closed down when the Great Depression hit. I don't think it ever had one patient.
