This book analyzes and describes the development and aspects of imagery techniques, a primary mode of mystical experience, in twentieth century Jewish mysticism. These techniques, in contrast to linguistic techniques in medieval Kabbalah and in contrast to early Hasidism, have all the characteristics of a full screenplay, a long and complicated plot woven together from many scenes, a kind of a feature film. Research on this development and nature of the imagery experience is carried out through comparison to similar developments in philosophy and psychology and is fruitfully contextualized within broader trends of western and eastern mysticism.
