The Cabala, it may be said briefly, in the primary meaning of the word, is the doctrine received by oral tradition as an important supplement to the written Jewish Scriptures, but the Cabala as we know it is an esoteric system which was formed under the influence of many streams of ancient thought-systems, and which came into vogue about the thirteenth century, though its devout adherents claimed that it had been orally transmitted through the intervening ages from Adam in Paradise. According to the teaching of the Cabala, the original Godhead, called _En-Soph_, the Infinite, is in essence {135} incomprehensible and immutable, and capable of description only in negations. God, the En-Soph, is above and beyond contact with anything finite, material, or imperfect. It would be blasphemous to suppose that God the infinitely perfect, God the absolutely immutable One, by direct act made a world of matter or created a realm of existence marked with evil as this lower realm of ours is. Instead of supposing a creative act, therefore, the Cabala supposes a series of emanations, or overflows of divine splendour, arranged in three groups of threes, called _Sephiroth_, which reveal all that is revealable in God, and by means of which invisible and visible worlds come into being. These _Sephiroth_, or orders of emanation, are _thoughts_ of the Wisdom of God become objectively and permanently real, just because He thought them; and though He is vastly, inexhaustibly more than they, yet He is actually immanent in them and the ground of their being. They are (1) the intelligible world, or world of creative ideas; (2) the world of spiritual forms, such as the hierarchies of angels, souls, and the entire universe of immaterial beings, the world of astral substance or of creative soul-matter; and (3) the natural world, in which the divine plan of Wisdom, the creative ideas, and the astral soul become visibly and concretely revealed. Man unites all the worlds in himself, and in his unfallen state as Adam-Cadmon combined all men in one ideal, undifferentiated Man. The visible world is full of hints and symbols of the invisible, and the initiated learn to read the _signs_ of things seen, the meanings of sacred letters, and so to discover the secrets and mysteries of the inner world. The Cabala is full of unrestrained oriental imagination, of fancies run riot, and of symbolisms ridden to death. Its confusion of style and thought and its predilection for magic unfortunately proved contagious, and played havoc with the productions of those who came under its spell. Its marvels, however, powerfully impressed the minds of its German readers. Through it they believed they were privileged to share in mysteries which had been hid from the creation of the world, and {136} they conceived the idea that they had at last discovered a clue that would eventually lead them into all the secrets of the universe.[2]
