An exploration of the complex relationship of Renewal interpretations of Kabbalah to classical forms of Jewish mysticism through teaching of the Four Worlds.  In classical Kabbalah, the Four Worlds described the structure of the cosmos as from the Godhead down through angelic realms to this material, corrupt world. Later, the four worlds became identified with meditation, as the mystic strove to leave this world behind for purer, holier worlds. Jewish Renewal took this liturgical aspect and "psychologized" it, understanding the worlds as aspects of human existence and stressing their correspondence with the Sabbath morning service.
