Jakin and Boas are the names of the two symbolic pillars of Solomon’s Kabbalistic temple, which were believed to explain all mysteries. One pillar was white, while the other one was black, thus the represented the powers of good and evil. It was said that they symbolize they need for “two” in the world: Human equilibrium requires two feet; the worlds gravitate by means of two forces; generation requires two sexes. A.G.H.
