Cayce's armageddon reasons ....

The following is an excerpt from an article entitled, "The Edgar Cayce Predictions":
Cayce predicted that the so-called “Battle of Armageddon” described symbolically in the Bible would begin in 1999. Cayce foresaw that this “battle” will not be a war fought on Earth. Rather, it will be a spiritual struggle between the “higher forces of light” and “lower forces of darkness” for 1000 years of Earth time. The reason for this struggle is to prevent souls from lower afterlife realms from reincarnating to Earth. By preventing souls from the lower afterlife realms from reincarnating to Earth, only enlightened souls will be permitted to reincarnate. The result will be 1000 years of building a world of peace and enlightenment. After 1000 years, souls from lower afterlife realms will be permitted once again to reincarnate to Earth. By this time, the so-called “kingdom of heaven” will have been established on Earth.
