I like that answer.
It connects to what I was going to write first, lazily, to your first claim, namely that Crowley would disagree, and refer you to the concept of Ipsissimus.
Now you created an actually viable content for me to do that, by this evocative phrase; “to know the unknowable”.
So here’s the concept, or one take on it:
Ipsissimus
10° = 1□Ipsissimus. — Is beyond all this and beyond all comprehension of those of lower degrees.
The Grade of Ipsissimus is not to be described fully; but its opening is indicated in Liber I vel Magi.
There is also an account in a certain secret document to be published when propriety permits. Here it is only said this: The Ipsissimus is wholly free from all limitations soever, existing in the nature of all things without discriminations of quantity or quality between them. He has identified Being and not-Being and Becoming, action and non-action and tendency to action, with all other such triplicities, not distinguishing between them in respect of any conditions, or between any one thing and any other thing as to whether it is with or without conditions.
He is sworn to accept this Grade in the presence of a witness, and to express its nature in word and deed, but to withdraw Himself at once within the veils of his natural manifestation as a man, and to keep silence during his human life as to the fact of his attainment, even to the other members of the Order.
The Ipsissimus is pre-eminently the Master of all modes of existence; that is, his being is entirely free from internal or external necessity. His work is to destroy all tendencies to construct or to cancel such necessities. He is the Master of the Law of Unsubstantiality (Anatta).
The Ipsissimus has no relation as such with any Being: He has no will in any direction, and no Consciousness of any kind involving duality, for in Him all is accomplished; as it is written “beyond the Word and the Fool, yea, beyond the Word and the Fool”.
[One Star in Sight sub figurâ CDLXXXIX]

In this tradition, being is seen to emerge from the boundless no-thingness, and the Ipsissimus has acquired access to that source and dwells there with a consciousness that is no longer strictly “his” - presenting all manner of paradox, of course, as enlightenment would to the not-yet-enlightened.
I do not mean for this to sway about the argument, but to point you to an interesting pocket of theory on the Self and its development. You may know Crowley as “the Beast” and related titles but really he was the closest to a prophet we’ve had in recent centuries, I find. He covers large parts of the field that Jung does not - where Jung only points towards, as Jung must remain scientist, whereas Crowley’s task was, in a sense, to simply go where no man had gone before, regardless of consequence. Jung was very conscientious, otherwise his work would have been valueless. For Crowley its the opposite, he needed to be completely rueckstichtlos. He stumbles around a great deal but also burst through seemingly solid walls and he gets truly inside the core of the psyche. Where, of course, it is rather chaotic, for lack of a better term; and what term is better than the delicious word Chaos?
Anyway. Good answer.
PS
I will link you to one of his most Chaotic book, “The Book of Lies”; You can see how he required to make such a tremendous mess of the mind, in order to cross over to the being of that Ouroboros.
