Volume Two, Hasidism, is devoted to the psychological and spiritual wisdom embodied in Jewish spiritual tradition. Relying on Jung's concepts and Buber's Hasidic interpretations, Neumann seeks alternatives to the legalism and anti-feminine bias that he says have dominated collective Judaism since the Second Temple. He argues that modern Jews can develop psychological wholeness through an appropriation of Hasidic legends, Talmudic texts, and Kabbalistic mysteries, including especially the Zohar. Exclusively, this volume includes a foreword by Moshe Idel. An appendix, Neumann's four-lecture series from the 1940s, gives a glimpse of his intended, unpublished Part Three.

These volumes anticipate Neumann's later works, including Depth Psychology and a New Ethic, The Origins and History of Consciousness, and The Great Mother. In Volume Two, Hasidism, his concept of the ego-Self axis is developed in clearly psychological terms. Four previously unpublished essays, appended to Volume Two, illustrate Neumann's developmental psychology, including his theme of primary and secondary personalization. This unique work will appeal to Jungian analysts and psychotherapists in training and in practice, historians of psychology, Jewish scholars, biblical historians, teachers of comparative religion, as well as academics and students.
