Shamdasani here explains the transformation that Jung is bringing to psychotherapy. The key to Jung’s transformation is found in the Black Books and Liber Novus. The focus of psychotherapy had been the treatment of a neurological disorder. Now it is to enable a development of the individual through a process of individuation. Patients were taught how to induce visions. They were to write their own Black Books, their own Liber Novus. The patients could find their own mythology.
