Edgar Cayce communicated with his own Oversoul. However, the universal timeline has been split (by the Montauk Project and other clandestine experiments with time) since he gave his readings, rendering most of his predictions invalid at this point. He was a great prophet and healer, but like White Feather said earlier in this thread, Cayce's readings were predominantly for people who lived from the 1920's through the 1970's.

Further, The Edgar Cayce Foundation in Virginia Beach, Virginia is very close to the large naval installations in Norfolk. The original information the Foundatrion put out was good, but it has been usurped over the years and now has become another outlet for New Agey material. Always read it with a discriminating eye.
