Edgar Cayce (pronounced Kay-Cee, 1877-1945) has been called the "sleeping prophet," the "father of holistic medicine," and the most documented psychic of the 20th century. For more than 40 years of his adult life, Cayce gave psychic "readings" to thousands of seekers while in an unconscious state, diagnosing illnesses and revealing lives lived in the past and prophecies yet to come. Later in life, Cayce would find that he had the ability to put himself into a sleep-like state by lying down on a couch, closing his eyes, and folding his hands over his stomach. In this state of relaxation and meditation, he was able to place his mind in contact with all time and space â€” the universal consciousness, also known as the super-conscious mind. From there, he could respond to questions as broad as, "What are the secrets of the universe?" and "What is my purpose in life?" to as specific as, "What can I do to help my arthritis?" and "How were the pyramids of Egypt built? His responses to these questions came to be called "readings," and their insights offer practical help and advice to individuals even today.
