I've spent many years being into this sort of thing, hermeticism, kabbalah, magick....
kind of a broad, disorganised subject, filled to the breaking point with confusion, misinterpretation, useful techniques, dangerous techniques and many confusing paths to wisdom and madness. An utter quagmire.
The terms hermeticism and magick are both just too bloated, too heavily loaded, they cover too much ground-- it makes this thread difficult to respond to.
Ask me about kabbalah. Or tarot. Or banishing, enchanting, divination, evokation, invokation. Or maybe ask me about occultism, the mystic side of things, tree of life, sacred geometry, general magickal philosophies, cosmologies and worldviews....many books on these diverse topics grace my bookshelves. A few of them disgrace my shelves as well. But I seem to be a lot less into it these days.
The utter reality of entheogenic experience is maybe replacing complex myth/symbol systems (for me) perhaps?
There's always the theory that ritual magick was only ever developed because the people lost the mushroom. Now that we've found the mushroom again do we still need these over-laden systems? That's entirely rhetorical.
Chaos magick was an awesome thing, a cleaning of house, a stripping away of useless clutter and a reduction of magick down to it's useful components....but the whole sigil magick thing, man, do we need more sorcerers? I mean, hermeticism is great if your into that (and I still am, a little bit) but it carries a lot of old baggage, a lot of concepts that seem decidedly Old Aeon to me...chaos magick did aweay with that and supplanted it with meta-belief, and meanwhile went and expanded A O Spares sigil work. That was cool, but in light of powerful entheogens, the chaos path just seems too carry such a sorcerous tendency.
