“All are the scales of universal harmony; justice and equilibrium are placed at the central point of the Zodiac. The grand circle of the heavens, so well discoursed upon by Plato, in his Timaeus, symbolizes the unknown as a unity; and the smaller circles which form the cross, by their division on the plane of the Zodiacal ring – typify, at the point of their intersection, life. The centripetal and centrifugal forces, as symbols of Good and Evil, Spirit and Matter, Life and Death, are also those of the Creator and the Destroyer, Adam and Eve, or God and the Devil, as they say in common parlance. In the subjective, as well as in the objective worlds, they are the two powers, which through their eternal conflict keep the universe of spirit and matter in harmony. They force the planets to pursue their paths, and keep them in their elliptical orbits, thus tracing the astronomical cross in their revolution through the Zodiac.
In their conflict the centripetal force, were it to prevail, would drive the planets and living souls into the sun, type of the invisible Spiritual Sun, the Paraatma or great universal Soul, their parent; while the centrifugal force would chase both planets and souls into the dreary space, far from the luminary of the objective universe, away from the spiritual realm of salvation and eternal life, and into the chaos of final cosmic destruction, and individual annihilation.
But the balance is there, ever sensitive at the intersection point. It regulates the action of the two combatants, and the combined effort of both, causes planets and “living souls” to pursue a double diagonal line in their revolution through Zodiac and Life; and thus preserving strict harmony, in visible and invisible heaven and earth, the forced unity of the two reconciles spirit and matter, and Enoch is said to stand a “Metatron” before God.
Reckoning from him down to Noah and his three sons, each of these represent a new “world”, i.e., our earth, which is the seventh after every period of geological transformation, gives birth to another and distinct race of men and beings. Cain leads the ascending line, or Macrocosm, for he is the Son of the “Lord”, not of Adam (Genesis 4:1). The “Lord” is Adam Kadmon, Cain, the Son of sinful thought, not the progeny of flesh and blood. Seth on the other hand is the leader of the races of earth, for he is the Son of Adam, and begotten “in his own likeness, after his image” (Genesis 5:3). Cain is Kenu, Assyrian, and means eldest, while the Hebrew word, נַפָּח, means a Smith, an artificer.”
