Enochian magick, as a system, isn’t too different from other systems of magick involving evoking and invoking spiritual forces to the Will of the Magician. In my experience, it’s much more powerful when comparing them more widely used systems involving planetary and elemental magick which those two, at least to me, seemed more subtle. It always felt like a supercharged effect that persists for several days on end.
The best part about magical systems is that you can use them for whatever you wish. If you’re making a sigil (I prefer the terms talisman and amulets) then you could just place elemental, planetary and angelic names on a shape or item that fits whichever your goal is. Money would be to Jupiter, so it can be a four-sided piece of paper with those same inscriptions on it, although alongside the Hebrew names of the angelic governor, you have Enochian, based around the Sigillum Dei Aemeth, with either the God name associated with it or with the planetary name along with a break down of certain angelic names that are assigned to the Sephira on the Tree of Life. That break down of the angelic names provides with more precision in terms of your goal and with the ordering of the universe (to a certain extant).
But aside from all that, it just depends on what your goals are. Some of the enochian calls, like the Table of Union, do invoke elementary forces (Fire, Water, Air, Earth) because those are the “lowest” forms of creation. By lowest I mean primal, as that is their essence that have qualities and conditions but do not have form in the physical world just yet and are more etheric.
Those visions are part of the mystical experience of becoming spiritually purified through magical means and harmonizing yourself with elementary forces (as a beginning step) so that you’re not off-balance. You should be able to acquire the knowledge of what is Earth (stable, placid) along with Air (mutable, changing) without them directing you. That’s really the basis, to some extant, of white magick but for grey magickal purposes and black magick (depending on how you define those terms) you could also use elemental powers but making an amulet/talisman/sigil for knowledge of how to shred the guitar at a much faster rate than learning without magickal means- which is usually why most people pick up magick. Again, the key is what your goals are.
There’s other books that go hand-in-hand with elemental and planetary forces that aid in that quest too so feel free to peruse around. I’m not entirely sure about summonings though as I’m not adept at that- I just never did so for any reason.
I felt the same way about the visions and storms I’ve seen but I now think that is it rather misleading to assume that’s all those Enochian forces do since those are just excerpts. Most of those visions happen randomly and people are rather skeptical when seeing those things. It makes sense, Enochian magick didn’t really come about the first time Dee made contact with the spirits, as it proved illusionary in the beginning.
