"One of my teachers, Rowena Pattee Kryder, has extensively developed work around topics that one might call "from the mystery schools."  That is, she has a combination of artwork, posters and card decks, with corresponding texts, that elucidate select programs from across the centuries that codified the perennial wisdoms into various systems of thought.  I have looked at these systems of thought because I have found that when our consults in art therapy tap into levels of consciousness, beyond those of the personal unconscious, self expressive arts imagery often flows from what Jung would call the archetypal levels of consciousness. I have found from my work with 1000's of consults by now, that these repositories of "useful wisdom imagery” have served living systems well, over the eons, and are presently stored in Jung's collective creative unconscious."
