Magick Liber ABA: The Sword
Shows the relationship between the magical dagger and the sword.
“THE word of the Lord is quick and powerful, and sharper than a two-edged sword.”
As the Wand is Chokmah, the Will, “the Father,” and the Cup the Understanding, “the Mother,” Binah; so the Magick Sword is the Reason, “the Son,” the six Sephiroth of the Ruach, and we shall see that the Pantacle corresponds to Malkuth, “the Daughter.”
The Magick Sword is the analytical faculty; directed against any demon it attacks his complexity.
Only the simple can withstand the sword. As we are below the Abyss, this weapon is then entirely destructive: it divides Satan against Satan. It is only in the lower forms of Magick, the purely human forms, that the Sword has become so important a weapon. A dagger should be sufficient.
But the mind of man is normally so important to him that the sword is actually the largest of his weapons; happy is he who can make the dagger suffice!
