A girlfriend of mine from college got her Ph.D. in Psych and went on to develop what she called an astrological approach to psychoanalysis; she ended up (last I heard, which was long ago and far away) with the Tibetan Buddhists out in Boulder, CO having change one mythos for another.

Tarot, astrology, the Bible, the Vedas, the T'ang and Sung poets, Shakespeare, Dr. Strange (Steve Ditko's version) - so long as you don't mistake the map for the territory, there's a lot to be learned from a well-crafted metaphor.
