Many of the world's religious traditions have regarded sexuality as a potent means of encountering the sacred. The Tantric schools of Buddhism have long used techniques of sexual yoga as a path toward enlightenment. Likewise, members of the Jewish mystical tradition of Kabbalism have seen sexual experience as revealing aspects of the sacred. Mircea Eliade says that "sexuality is at one and the same time a physiological activity and a sacrament. . . . [T]hroughout religious history, sensory activity has been used as a means of participating in the sacred and attaining to the divine."
