Things are not as complex, as you make them to be.
It is not something that needs a “mystic”. In fact, all those things about the four elements and the like are not Metaphysics at all (Metaphysics does concern matter and form, substances and accidents, but not the four elements). They are Physics. State-of-the-art for its own time, obsolete now.
Four elements explain why Atmosphere is above Lithosphere and Hydrosphere, why Hydrosphere is above Lithosphere. Now we have better explanations for that (Newtonian mechanics, General Theory of Relativity). And, in fact, they cause less difficulties to Aristotelian Metaphysics! After all, it took some effort to Aristotle to explain why, let’s say, stone’s falling down is not self-caused (
dhspriory.org/thomas/Physics8.htm#8), while now we can easily say that this movement is caused by gravitational field or curved space, which, in turn, is caused by Earth.
OK, now, why exactly are you reading books by someone whom Wikipedia describes as “an occult writer” (
en.wikipedia.org/w/index.php?title=Heinrich_Cornelius_Agrippa&oldid=775394910)? And, given the URL, most likely precisely the books that concern just that “field”?
That doesn’t look encouraging and it is highly unlikely to have anything to do with Aristotle, Thomism - or anything else that is good for you in any way. I would strongly recommend to stay away from it.
