This comes from contemplation of Crowley's comments on Liber AL I, 45:
"The Perfect and the Perfect are one Perfect and not two; nay, are none!"
Crowley tells us that the characteristically difficult passage, one of several in Liber AL, is used in part by Aiwaz to "identify Himself".
Why identify Himself in difficult passages, if Aiwaz's only function, which has already been announced, is a messenger boy?
In fact, what this verse tells us is the product of the combination of the two kinds of Perfect, Nuit and Hadit, is only apparently two, and effectively one, again Perfect, and in reality however NONE. The equation is Life via Annihilation, or 0=2. What this tells us is that the deepest, trans-Aeonic, message of Liber AL is that the point of the cosmos itself is NOTHING, or Zero. And the very god to whom Aiwaz is said to be Minister, Hoor-paar-Kraat, is the God of Silence, or NO sound, thus nothing. Hoor-paar-Kraat's nothingness is nevertheless a complex as well, the annhilation of a positive, male expression, because he corresponds to Aleph or One, and the negative, female expression, being the Tarotic Fool, or Zero, to which of course Aleph is corresponded. One problem with this notion is that Zero, at least in the Fool, is still a positive expression, and is not in fact negative, but it suggests or points to the Veil of the Triple Negative which precedes and gives rise to the positive expression.
Crowley says, at the moment Aiwaz reveals his message of Silence, and Nothingness, these are activated into the martial Expression of the marriage of Nuit and Hadit, which is the god Ra-Hoor-Khuit, the star of Chapter III of Liber AL. While Ra-Hoor_Khuit is certainly not a silent or Invisible god, his twin still follows him, like a shadow, and Together they are parts of the unified form of their expression, Heru-ra-ha, the "'true Name' of the Unity". This Heru-ra-ha is "the one Perfect and not two", which is to say "two" amounting to "not" or Nothing, and so the equation is balanced, as it always must be, 0=2.
Lastly, Aiwaz is of course the Revealer, and chief Earthly representative of the the tripartite Nothing below, mirroring the tripartite Nothing above (Triple Veils), which is to say:
3 x 31 (LA, "not", also AL, "god") = 93-Aiwaz, or Minister Zero.
