What helped me most is applying my philosophical and theological findings to mundane life. Like "ah, a path of this sort has a worse overall geometry than the other path", or "the geometry of the bird flock high above me reminds me of X principle, I'll take it as such", "this tree bears this kind of geometry, which reminds me of Y principle of metaphysics, therefore we can assume that it shares within that essence more than not", and so on.
Unconventional method, but the essence of it is: apply your knowledge to mundane observations, nothing too specific and it works best if it's just a random plant/person/object/weather event/animal you hadn't planned. Sequences of events, features of the land, even the people you meet, and so on - these help most. You'll find yourself feeling more sensitive if you manage it, and your knowledge will feel more "braided together"/instinctual to recall.
Other than this, just learn mathematics. Whitehead's "Introduction to Mathematics" is pretty good because he's essentially saying "Mathematics is abstracted metaphysics with letters instead of full words, and equations are basically just abstract principles in a specific relation" - though Whitehead doesn't quite fully admit "yeah this is ancient metaphysics". Essentially, it is geometric in presentation, just like metaphysics is geometric in presentation. Mathematics and the way Whitehead presents them can both help you apply metaphysical principles in ritual and everyday life much more than you'd think.
For example, when doing a ritual to an Earth deity, how many corners do you have for the space? Four, ideally, because four is one of the most geometrically stable shapes... with low, grounded frequencies as colours (metallic greys, browns, muted colours in general - the frequency of the wavelength must match, as must the geometry if you want the best results), and so on. You can deduce these details, and even finer ones, by applying mathematical principles combined with a metaphysical symbolic understanding of the mathematical relations.
I also highly recommend Thomas Taylor's translation of the "Elements of Theology" - it's basically the closest metaphysics comes to algebra.
