The Sephirothic Tree consists of ten globes of luminous splendor arranged in three vertical columns and connected by 22 channels or paths. The ten globes are called the Sephiroth and to them are assigned the numbers i to 10. The three columns are called Mercy (on the right), Severity (on the left), and, between them, Mildness, as the reconciling power. The columns may also be said to represent Wisdom, Strength, and Beauty, which form the triune support of the universe, for it is written that the foundation of all things is the Three. The 22 channels are the letters of the Hebrew alphabet and to them are assigned the major trumps of the Tarot deck of symbolic cards.
THE Tree of the Sephiroth may be considered an invaluable compendium of the secret philosophy which originally was the spirit and soul of Chasidism.
According to the Hebrew system of Qabbalism, the Tree of the Sephiroth was divided into two parts, the upper invisible and the lower visible. The upper consisted of three parts and the lower of seven. The three uncognizable Sephiroth were called Kether, the Crown; Chochmah, Wisdom; and Binah, Understanding. These are too abstract to permit of comprehension, whereas the lower seven spheres that came forth from them were within the grasp of human consciousness. The central panel contains seven triads of figures. These represent the lower Sephiroth, all emanating from the concealed threefold crown over the throne.
