Cayce had difficulty in believing some of the things he said when he was hypnotized. For example, having been raised a devout Christian, for a long time he could not believe that reincarnation was real. Books such as Frederick Oliver's A Dweller On Two Planets and Marie Corelli's novels were probably easily accessible to Cayce at his bookstore. Corelli's writings in particular seek to reconcile mystical beliefs such as reincarnation with Christianity, and Cayce may have been subconsciously trying to accept this idea.
