This guide to an extraordinary tradition of visionary experience is translated and introduced by a prominent rabbi, the author of such works as "Hasidic Prayer". It traces the mystic tradition as it exists throughout the history of Judaism. Mysticism is at least as ancient as the Book of Ezekiel and its influence can be clearly discerned in Jewish culture of modern times. This annotated collection of Jewish mystical testimonies ranges from Ezekiel in the world and time of the Torah down the millennia and across all the Diaspora. It includes pages from the enigmatic Zorah; the great Jewish writers of the medieval world; and Aaron Roth, whose visions of dungeons and fire seemed to foreshadow the Holocaust.
