The Zohar is the great medieval compendium of Jewish esoteric and mystical teaching, and the basis of the kabbalistic faith. It is, however, a notoriously difficult text, full of hidden codes, concealed meanings, obscure symbols, and ecstatic expression. This illuminating study, based upon the last several decades of modern Zohar scholarship, unravels the historical and intellectual origins of this rich text and provides an excellent introduction to its themes, complex symbolism, narrative structure, and language. A Guide to the Zohar is thus an invaluable companion to the Zohar itself, as well as a useful resource for scholars and students interested in mystical literature, particularly that of the west, from the Middles Ages to the present.
