Robert W. Huffman and Irene Specht's book "Many Wonderful Things: An Incredible Journey into Light" describes hypnotic experiments carried out over two years by hypnotist Robert Huffman with a group from the Boulder Fellowship Foundation. They claimed to have discovered evidence that humans have a "third mind—a God mind, a part of God within himself". The book claims to provide answers to spiritual questions such as: "Where can I find God? What is God like? How can I truly contact Him? Is there really life after death?" The original edition (1957) was 377 pages long and featured a dark blue hardcover with gold text. It has been reprinted in many editions. Kindle edition available here.
