“Later on this wickedness is followed by the magical prostitution of evil, or the act of Magical Incest, through the intermingling of the Sons of God (the demoniac powers engendered by the disruption of Tetragrammaton) with the daughters of men–the carnal lusts of humankind.
Here is symbolized a process of leveling down (a carnal communism) and not of rising up, and the result is the establishment of Black Magic, the earth being peopled by “mighty men,” or despots. Why not White Magic? Because the Sons of God (the Above) came down to the daughters of men (the Below); that is light absorbed by darkness.
Thus mankind sank into the Qliphoth, the reflection of the world of Assiah upon the chaos of human passions, and Hell is created–the materialized mental pit. Thus also it came about that the world became corrupt and filled with violence, and to redeem it it was necessary to destroy it, except for Noah and those in the Ark.
Noah was, however, far from perfect; consequently we find that after the deluge he profanes the Mysteries, “And he drank of the wine, and was drunken; and he was uncovered within his tent” and, his son Canaan divulging this profanation, is cursed. Thus magic, in spite of the repentance of Tetragrammaton, continued to grow until the repopulated world cried:
“Go to, let us build a city, and a tower whose top may reach unto heaven; and let us make us a name,” that is an object of worship, for they had a crafty design to rid themselves of the Supreme Power and to transfer His glory to another.”
“The inner meaning of the Tower of Babel is that any attempt to possess the secrets of heaven in order to divulge them to the uninitiated on earth must lead to misunderstanding and anarchy–a confusion of tongues, that is of false symbols. A universal pentacle cannot be constructed for the unpurified multitudes, for the multitudes can only comprehend parables.”
