These mystical treatises constitute the centre around which cluster all the productions of this school, which gradually came into existence in the course of time. So numerous became the disciples of mysticism in the twelfth century, and so general became the belief in their power of performing miraculous cures, driving out evil spirits, &c., &c., by virtue of charms consisting of the letters composing the divers divine names transposed and commuted in mystical forms, that the celebrated Maimonides found it necessary to denounce the system. “We have one divine name only,” says he, “which is not derived from His attributes, viz., the Tetragrammaton, for which reason it is called Shem Ha-Mephorash (‏שם המפורש‎). Believe nothing else, and give no credence to the nonsense of the writers of charms and amulets (‏כותבי הקמיעות‎), to what they tell you or to what you find in their foolish writings about the divine names, which they invent without any sense, calling them appellations of the Deity (‏שמות‎), and affirming that they require holiness and purity and perform miracles. All these things are fables: a sensible man will not listen to them, much less believe in them.” (More Nebuchim, i, 61.) But this mysticism, with its thaumaturgy, though espoused by later Kabbalists and incorporated into their writings, is perfectly distinct from the Kabbalah in its first and pure form, and is to be distinguished by the fact that it has no system, knows nothing of the speculations of the En Soph, the ten Sephiroth, the doctrine of emanations, and the four worlds, which are the essential and peculiar elements of the Kabbalah. As to Franck’s ingenious hypothesis, based upon the same number of letters constituting a divine name, mentioned in the Talmud, and the ten Sephiroth, we can only say that the Kabbalists themselves never claimed this far-fetched identity, and that Ignatz Stern has shown (Ben Chananja, iii, p. 261), that the Sohar itself takes the ten divine names mentioned in the Bible, which it enumerated in vol. iii, 11 a, and which it makes to correspond to the ten Sephiroth, to be the sacred name composed of forty-two letters, viz.:— 4 + 2 + 2 + 5 + 4 + 5 + 2 + 5 + 2 + 4 + 3 + 4 = 42 ‏אדני‎ ‏חי‎ ‏אל‎ ‏צבאות‎ ‏ידוד‎ ‏אלדים‎ ‏אל‎ ‏ידויד‎ ‏יה‎ ‏אהיה‎ ‏אשר‎ ‏אהיה‎
