Edgar
Cayce is a very famous psychic who had predictions and prophecies about
2012, the pole shift (polar shift) and many other pieces of information
about the Earth Changes that are coming with the date of December 21,
2012. He did not speak specifically about 2012, but rather his
predictions were supposedly going to happen by the year 1998. His
predictions were off and he had the timeline incorrect.
That
is the trouble with predictions, it is hard to nail down the time at
which they will happen specifically. That is the hardest part about
prophecy: nailing down the timeline. Edgar Cayce's predictions are still
thought to have much weight and probability. It is just that the
timeline is off in his predictions. He suggested all these things would
happen sooner than they are appearing in physical reality. They still
might appear but at a later time. In fact, Cayce suggested that it would
take generations for some of these things to come to pass. Shifting
planets could take a long time to finish the process of rearranging
themselves. Maybe that's where the 1000 years of peace on Earth come in,
at least as far as the humans are concerned.
