Archetypal psychotherapy is one of the depth psychotherapies in the lineage of psychoanalysis and Jungian analytical psychology, all of which share a dialogical approach to engaging unconscious material. It is talk therapy in which the talk is operating at multiple levels, including the levels of the personal and collective unconscious. It is based on the theories of the post-Jungian field of archetypal psychology. This body of theory, which calls for a new understanding of the nature of the psyche itself and a new orientation to symptoms, has significant implications for the practice of psychotherapy, some of which are quite paradoxical in the context of mainstream suppositions about mental health.
