Designed as a reference work for the student and general reader, this Kabbalistic dictionary is a concise and handy guide to the history and treasures of the Jewish mystical tradition. It is the first dictionary of Kabbalah to provide an overview of the major themes of Jewish Kabbalistic thought as it developed over the centuries and also contains brief introductions to its major practitioners. In addition to the dictionary itself, the book contains a chronology of Kabbalah, a history of Kabbalah from ancient times to the present, maps, illustrations and an insight into the emergence of the Kabbalah Centre in California, where many celebrities, including Madonna, worship.
