“Yet must he that understandeth go forth unto the outermost Abyss, and there must he speak with him that is set above the four-fold terror, the Prince of Evil, even with Choronzon, the mighty devil that inhabiteth the outermost Abyss. And none may speak with him, or understand him, but the servants of Babylon, that understand, and they that are without understanding, his servants.”
— DEO, the 7rd Aethyr

Consider also:

  1. “by a peculiar Ordinance of Heaven, and a Disposition occult within his Mind, is every Man protected from this Loss of his own Soul, until and unless he be by Choronzon disintegrated and dispersed beyond power of Will to repair; as when the Conflict within him, rending and burning, hath made his Mind utterly desert, and his Soul Madness.”
  2. “Somewhere along the way from one side to the other, Crowley says, the magician must also confront and temporarily become the ‘Demon of the Abyss’, whose nature is Dispersion. Crowley named this demon Choronzon, a name for Satan from the works of Dr. John Dee; but the characteristics he assigns to the demon owe more to the ‘Dweller on the Threshold’ from Bulwer-Lytton’s Zanoni novels. It is unclear how this confrontation relates to the destruction of the magician’s human self.”
  3. “CXVII As I come through the ordeal which is bliss, Careful I tread to avoid the Abyss And escape the clutches of Choronzon! I raise up the cup and adore Babalon!”
  4. “For know that I am proud and revengeful and lascivious, and I prate even as thou. For even as I walked among the Sons of God, I heard it said that P. . . . could both will and know, and might learn at length to dare, but that to keep silence he should never learn. O thou that art so ready to speak, so slow to watch, thou art delivered over unto my power for this. And now one word was necessary unto me, and I could not speak it. I behold the beauty of the earth in her desolation, and greater far is mine, who sought to be my naked self. Knowest thou that in my soul is utmost fear? And such is my force and my cunning, that a hundred times have I been ready to leap, and for fear have missed. And a thousand times am I baulked by them of the City of the Pyramids, that set snares for my feet. More knowledge have I than the Most High, but my will is broken, and my fierceness is marred by fear, and I must speak, speak, speak, millions of mad voices in my brain. With a heart of furious fancies, Whereof I am Commander, With a burning spear And a horse of Air To the wilderness I wander.”
