Thank you!—but oof, I think you're going deeper than the level of introduction I was thinking of, since I'm not sure I follow. I assume "spiritual alchemy" since I have no interest in the material, but other than Lawlor I'm not studied in the models you're working with (e.g. no Tarot, no Tree of Life, no Cosmic Doctrine, etc.). Perhaps the best place for me to start is de Lubicz, since it's still sitting on my shelf, and come back to all this later on...
