Mysticism, Psychology and Oedipus, from the Small Gems series is one of these mysterious alchemys which Regardie and Spiegelman crafted for the serious student of mysticism. MYSTICISM, PSYCHOLOGY AND OEDIPUS by Dr. Israel Regardie and his friend, world renowned Jungian Psychologist, J. Marvin Spiegelman, Ph.D. was created to reach the serious student at the intersecting paths of magic, mysticism and psychology. While each area of study overlaps they also maintain their own individual paths of truth. One of Regardies greatest gifts was his rare ability to combine these difficult and diverse subjects and make them understandable.
