Heh. That we are still talking about Crowley is what he wanted.
'Ex' O.T.O. here and more grim trad since the 1990's. I am still what I think of as "small-t" Thelemite. I was never a member of the A∴A∴, so I defer to those within that tradition to speak on it from their own experience. So this is my take and observations only.
I highly recommend reading Crowley through a Chaos Magic "meta-model" - which I don’t feel he would find objectionable. It helps avoid these neo-religous "magical" debates. In the mid 1990s, I was a member of the local body and was chatting casually with Fr. Dionysus about Chaos Magic. He felt the whole Peter Carroll
oeuvre is essentially Crowley with the mythopoetic "Thelemic" symbolism and mythic characters removed. And I agree.
See the opening of
Liber O vel Manus et Sagittae.
If you who have only read Aleister Crowley's writing, let me add the "boots-on-the-ground" expression in Thelemic culture is much more light-handed than his writing appears. Some of the coolest people and magicians I have met are in the O.T.O., and I found instant acceptance and camaraderie. (yes there are some crazy loons, but that is true of all groups). Goetia and sorcery is my jam, and the Order is more a fraternity, so I had to leave , because i had stuff I needed to do and attend to at the time (and did, often by applying Thelemic "force-and-fire" principles) . But I adore those folks.
Although I have been more "grim-trad" since the late 1990s (with a Zen Buddhist and Folk Catholic mystical practice), I highly recommend reading Crowley for a very deep mythopoetic and practical framework.
It is not necessary to take it literally. There has been a push online to turn the "Thelemic pantheon" into more neopagan gods, which is fine, but it totally acceptable to treat them as "mathematical expressions" in the universe. The whole famework is very felxible.
--------------------------------
Speaking more personally, The Book of the Law is pretty great.
I highly recommend the English Qaballa of Jim Lees' group, including Cath Thompson’s writing and Jake Stratton-Kent’s
The Serpent Tongue for a very - words fail here -
sublime vision of Liber AL. I am also not suggesting you take it as literally true, just that it "speaks" to us through whatever Aiwass is, by way of Rose Edith Kelly. I will say, reading parts of JSK's book, I had a mystical vision - and however you think of that is fine here - that put me into an ecstatic, joyful state for three whole days.
And then there is the A∴A∴, which uses a "buddy system" but can also be done without one. It is a pretty grat format to structure your training. At a certain point, once you have "trained" your emotions (Yesod) and your intellect/mind (Hod), in my opinion, you sort of need to move on to something more flavorful, emotional, and personal (Netzach). I leave than an open question if that is needed for the HGA experince.
Crowley taught me what he called "energized enthusiasm," which I see as total immersion, with your whole being, into ritual so you "get caught up" in it, with your all. Then the daimons show up. For me, this happened using the Grimorium Verum. They showed up, did crazy cool stuff, like walking through walls, and hanging out. You will be glad for the yoga and meditation when they do.

At the grade of Philosophus (4=7),which is associated with the sphere of Netzach, one might look toward
Liber Astarte vel Berylli for when it's time to 'make something your own' - and which can also be totally outside the Thelemic "pantheon." Nobody in the OTO I knew expected you to "stay on the farm." If they do, odds are they are one of the terminally online dummies trying to herd you. Ignore them.

I detoured from the HGA (Holy Guardian Angel) into the sublunar world, and the world of passions, but I also wanted to. But I came back. A bit of Jung fits here: Life itself IS initiation. You are always on the road to individuation. Thelema just gives you a decent map for it.
(I will say it does not have a well-developed sublunar theology, like you find in Vodou, Goetia, or Catholicism, but that was not really Crowley's concern. He was a mystic, not a sorcerer, and - frankly had nothing useful to add to Goetia. So to turnt o him as an authoruity here is like asking a Catholic priest for advice on sex. They maybe did it once or twice, , but not really their thing. )
Oh. And Liber ASTARTE for when it's time to make something you own, which can also be outside the Thelemic "pantheon. " Nobody in the OTO I knew expected you to "stay on the farm". If they do, oddd are theya are one of the dummies trying are trying to herd you. Ignore them.
