These post-mortem communications became the basis for a lengthy series of books which resulted in her achieving minor celebrity status, when Montgomery became a regular on the morning talk show circuit.
Montgomery, whose prolific New Age writings earned her a loyal and enthusiastic following, believed her mission on Earth was to educate the public regarding her views on life after death, which is not uncommon among spiritualists.
Montgomery wrote of such things as birth marks indicating the possible sites of past life injuries and commented that often children born with serious defects or illnesses are in fact repaying debts incurred in previous existences.
Her books sometimes discussed the past lives of the famous among her contemporaries, stating that Ernest Hemingway had once been a Hun warrior and that in a previous incarnation Jacqueline Kennedy was a famed French queen.
Echoing the earlier predictions of Edgar Cayce, Montgomery believed that ancient advanced civilizations of Mu and Atlantis had destroyed themselves thousands of years in the pre-history of modern man.
Montgomery predicted in the 1970s (with the help of her supposed spirit guides) that World War III would begin in the mid-1980s when a brush-fire conflict, started by Ethiopian strongman Mengistu Haile Mariam, would spread first to the Middle East, and then Europe.
Except for Florida and the coast of California, the Guides reported, most of America will survive, a direct contradiction of Montgomery's earlier forecast of significant global destruction in the coming event.
Alleged extraterrestrial candidates include far-reaching public figures such as technology visionary Steve Jobs, psychic medium Danielle Egnew and the Dalai Lama.
[8] Montgomery was a prolific writer on the subject of clairvoyance, reincarnation, past life regression, psychic phenomena, and clandestine extraterrestrials, most of which were sold as popular mass market paperbacks.
