Matter may be stimulated by the inner psychic process, understood archetypally, to produce something analogous. A latent tension, for example, can manifest itself in creaking wood. Matter plays along with the psychic process. There is a story that says that when Mohammed ascended into Heaven the stone in the Temple of Jerusalem wanted to go too. The archetype manifests itself in the outer world as sympathia. ~Carl Jung, Conversations with C.G. Jung, Page 51.
