prescribed ritual of proved efficacy during the very act of prayer. Thus mysticism had a farther attraction for a certain class of Jews, in that it supplied the missing element of asceticism which is indispensable to men more austerely disposed than the average Jew. In the sixteenth century a very strong impetus was given to Jewish mysticism by Isaac Luria (1534-1572). His chief contributions to the movement were practical, though he doubtless taught a theoretical Cabbala also. But Judaism, even in its mystical phases, remains a religion of conduct. Luria was convinced that man can conquer matter; this practical conviction was the moving force of his whole life. His own manner of living was saintly; and he taught his disciples that they too could, by penitence, confession, prayer, and charity, evade bodily trammels and send their souls straight to God even during their terrestrial pilgrimage. Luria taught all this not only while submitting to Law, but under the stress of a passionate submission to it. He added in particular a new beauty to the Sabbath. Many of the most fascinatingly religious rites connected now with the Sabbath are of his devising. The white Sabbath garb, the joyous mystical hymns full of the Bride and of Love, the special Sabbath foods, the notion of the 'over-Soul'--these and many other of the Lurian rites and fancies still hold wide sway in the Orient. The 'over-Soul' was a very inspiring conception, which certainly did not originate with Luria. According to a Talmudic Rabbi (Resh Lakish, third century), on Adam was bestowed a higher soul on the Sabbath, which he lost at the close of the day. Luria seized upon this mystical idea, and used it at once to spiritualise the Sabbath and attach to it an ecstatic joyousness. The ritual of the 'over-Soul' was an elaborate means by which a relation was established between heaven and earth. But all this symbolism had but the slightest connection with dogma. It was practical through and through. It emerged in a number of new rites, it based itself on and became the cause of a deepening devotion to morality. Luria would have looked with dismay on the moral laxity which did later on intrude, in consequence of unbridled emotionalism and mystic hysteria. There comes the point when he that interprets Law emotionally is no longer Law-abiding. The antinomian crisis thus produced meets us in the careers of many who, like Sabbatai Zebi, assumed the Messianic role.
