Actually, I came to take Crowley's (Golden Dawn) Tarot attributions with a grain of salt. Did you notice that there are three "mother letters" that belong to the elements according to the
Sepher Yetzirah, just like there are three horizontal paths on the ToL? Further, there are seven letters that belong to the planets, and seven vertical paths on the ToL. And then there are twelve paths that belong to the zodiacal signs, much like there are twelve diagonal paths on the ToL. However, Crowley (the GD) didn't take any of this in account.
This is not to say that one shouldn't consider these attributions. After all, the Thoth refers to them. But I'm not sure how much regarding thr significance of the cards can be deduced based on the given Kabbalistic attributions (of course, it's easy to rationalize anything). I doubt that they are the crux of the matter.
Talking about the affirmations that the OP wishes to link to the Thoth cards, and just to shock the traditionalists here a little more
, Ziegler's
Mirror of the Soul is chock full with them.
My personal approach to journaling the Thoth cards is to write down whatever I come up with myself or find in the literature regarding their interpretations, if it clicks.
