From Wikipedia:
Edgar Cayce (/ˈkeɪsiː/; March 18, 1877 – January 3, 1945) was an American mystic who allegedly possessed the ability to answer questions on subjects as varied as healing, reincarnation, wars, Atlantis and future events while in a trance. These answers came to be known as “life readings of the entity” and were usually delivered to individuals while Cayce was hypnotized. This ability gave him the nickname “The Sleeping Prophet”. Cayce founded a nonprofit organization, the Association for Research and Enlightenment[1] that included a hospital and a university.
He is credited as being the father of holistic medicine and the most documented psychic of the 20th century. Hundreds of books have been written about him and his life readings for individuals. Though Cayce himself was a member of the Disciples of Christ and lived before the emergence of the New Age Movement, some consider him the true founder and a principal source of its most characteristic beliefs.[2]
Cayce became a celebrity toward the end of his life, and he believed the publicity given to his prophecies overshadowed the more important parts of his work, such as healing the sick and studying religion. Skeptics[3] challenge Cayce’s alleged psychic abilities and traditional Christians also question his unorthodox answers on religious matters such as reincarnation and the Akashic records.
