“In the mysterious Sephirothic Tree of the Jews, these two pillars symbolize Mercy and Severity. Standing before the gate of King Solomon’s Temple, these columns had the same symbolic import as the obelisks before the sanctuaries of Egypt. When interpreted Qabbalistically, the names of the two pillars mean “In strength shall My House be established. “In the splendor of mental and spiritual illumination, the High Priest stood between the pillars as a mute witness to the perfect virtue of equilibrium – that hypothetical point equidistant from all extremes. He thus personified the divine nature of man in the midst of his compound constitution – the mysterious Pythagorean Monad in the presence of the Duad. On one side towered the stupendous column of the intellect; on the other, the brazen pillar of the flesh. Midway between these two stands the glorified wise man, but he cannot reach this high estate without first suffering upon the cross made by joining these pillars together. The early Jews occasionally represented the two pillars, Jachin and Boaz, as the legs of Jehovah, thereby signifying to the modern philosopher that Wisdom and Love, in their most exalted sense, support the whole order of creation – both mundane and supermundane.

The column on the right, which is called Jachin, has its foundation on Chochmah, the outpouring Wisdom of God; the three globes suspended from it are all masculine potencies. The column at the left is called Boaz. The three globes upon it are feminine and receptive potencies, for it is founded in Understanding, a receptive and maternal potency. Wisdom, it will be noted, is considered as radiant or outpouring, and Understanding as receptive, or something which is filled by the flowing of Wisdom. The three pillars are ultimately united in Malchuth, in which all the powers of the superior worlds are manifested.”
