Edgar Cayce's spiritual concepts and methods complement the lessons in the classical Chinese book, The Secret of the Golden Flower: A Chinese Book of Life. Both teach that we may be personalities In material bodies surrounded by a world of activity and relationships, but we are also celestial beings, sparks of life, only temporarily incarnating. Thus, it is good to experience our infinite, eternal self and its origin. By studying and practicing Cayce and Taoism, Van Auken states that he experienced a journey to what the Taoist master called, "the womb of our pure heart and clear mind."
