Now, in a completely revised and updated edition, Dr. Singer incorporates the latest developments in Jungian psychology, particularly in the areas of masculine/feminine relationships, psychotherapeutic drug use, and the evolution of Jung’s concepts and their applicability both clinically and in the world of business and industry. This new version of Boundaries of the Soul reaffirms its long-standing reputation as the best available introduction to Jung’s thoughts.
