a. The Square and Compass
Blue Lodge Masons are taught that the Square is to remind them that they must be "square" in their dealings with all men, i.e., to be honest. The Compass, they are taught, is to teach them to "circumscribe their passions," i.e. to control their desires and to be temperate. The real meaning of these "great lights," however, is sexual. The Square represents the female (passive) generative principle, the earth, and the baser, sensual nature; and the Compass represents the male (active) generative principle, the sun/heavens, and the higher, spiritual nature. The Compass, arranged above the Square, symbolizes the (male) Sun, impregnating the passive (female) Earth with its life-producing rays. The true meanings, then are two-fold: the earthly (human) representations are of the man and his phallus, and the woman with her receptive cteis (vagina). The cosmic meaning is that of the active Sun (deity, the Sun-god) from above, imparting life into the passive Earth, (deity, the earth/fertility goddess) below and producing new life (2)
b. The Letter "G"
The Blue Lodge Mason is taught that the "G" in the Masonic symbol represents God. Later on, he is told that it also represents "deity." Later still, he is told that it represents "geometry." In reality, this letter represents the "generative principle," the Sun-god and, thus, the worshipped phallus, the male "generative principle…" In its position (along with the Square and Compass) on the east wall over the chair (throne) of the Worshipful Master, it is the representation of the Sun, thus of the Sun-god, Osiris. Its earthly meaning, then, is of the sacred phallus; its cosmic meaning is of the Sun, worshipped since antiquity by pagans while facing the East. (See c, below).
