The Greatest Key of Solomon

I will now give unto thee the Key of the Kingdom of the Spirits. This key is the same that of the Mysterious Numbers of Yetzirah. The Spirits are governed by the natural and universal Hierarchy of things. Three command, Three through the medium of three. There are the Spirits of above, those of below, and those of the center; then if thou invests the Sacred Ladder, if thou descendent instead of ascending thou wilt discover the Counter-Hierarchy of the shells, or of the Dead Spirits. I know thou only that the principalities of heaven, the virtues, and the powers, are not persons, but dignities. They are the degrees of the Sacred Ladder upon which the Spirits ascend and descend.
