Psi: Scientific Studies of the Psychic Realm

This is the first book-length report of the thinking and studies of one of America?s foremost investigators of the psychic realm. Tart, an international authority on human consciousness, has studied such aspects of psi as telepathy, out-of-the-body experiences, and the human aura. Here he goes beyond the usual arguments for or against the existence of psi and instead discusses what we know about it and its implications for understanding our human and spiritual nature.
