Doyle was the author of Sherlock Holmes, and a spiritualist from the early twentieth century. He predicted, with this book, the coming of a spiritually based religion influenced by the spiritualist movement of his time, which included channeling, seances, automatic writing, and other strange, psychic occurrences. He investigated these things thoroughly and believed these realms held more answers than any standard religion. The Old Revelation, Doyle says, has lost its power through bigotry, mismanagement, materialism, and claims of infallibility that no longer hold up. New discoveries await us, and one can start to explore them now by reading this classic work. Paperback , ISBN 9781585092208 , 6 x 9 , 124 pp.
