The "Real Kabbalah" consists of theoretical and practical mysteries.
1. The theoretical mysteries treat about the ten spheres, the four worlds, the essence and various names of God and of angels, also of the celestial hierarchy and its influences and effects on this lower world, of the mysteries of creation, of the mystical chariot described by the Prophet Ezekiel, of the different orders and offices of angels and demons, also of a great many other deep subjects, too deep for comprehension.
2. The practical Kabbalah is a branch of the theoretical, and treats of the practical use of the mysterious names of God and of angels. By uttering properly the Shem-ham-mephorash, i.e., the ineffable name of Jehovah, or the names or certain angels, or by the mere repetition of certain Scripture texts, miracles and wonders were and still are performed in the Jewish world.
