This book acquaints the reader with the world of the Kabbalah. The first part discusses the Kabbalist as a person: the personal transmission of Kabbalistic traditions, the Kabbalist's qualities and qualifications, prerequisites and early preparations, risks and achievements, as well as techniques for uncovering mysteries and the sources of revelations. The second part deals with the major themes in the teachings of the Kabbalah, such as the doctrine of the Sefirot, the Sitra-Ahra--good and evil, the creation of the world, the status of the Torah and its commandments, the doctrine of the soul and the transmigration of souls. In treating these issues, the book also notes the assimilation of Kabbalistic notions in Jewish religious customs.
