JACHIN and BOAZ
"These pillars symbolize the heart and mind, the positive and the negative poles of life. Those who would enter the temple must pass BETWEEN the pillars. Every extreme is dangerous. It is the point between all poles that is safe to stand upon. You cannot enter the temple by the development of either the heart or mind alone, but only by the equal development of both." [Manly Palmer Hall]
Eliphas Levi
"The Chariot of Hermes has attached to its car a white and also a black Sphynx; each of these symbolic animals propounds an enigma to the neophyte. The word of the White Sphynx is Jachin. The word of the Black Sphynx is Boaz.
Hermes, seated in the Chariot, touches the Black Sphynx with the point of a sword of steel, but the White Sphynx with a sceptre of gold.
It is after the type founded by the Thrice Great Hermes that the Magus learns how to use the Magical Wand and the Sword to control good and evil powers and beings." [The Magical Ritual of the Sanctum Regnum by Eliphas Levi]
