A lot of this sounds like it’s from the Kybalion/Hermetic principles, which I thought was the basis for most modern magical practices, and even ancient ones. I thought this integration was a natural consequence of practicing magic, at least for advanced practitioners. Leaning on outside forces to bring about results seems, to me, like a beginner thing. Eventually we move past that, and realize the reason behind their existence.
It’s surprising, to me, that no one has put those pieces together, because in my short time, my spiritual mentors have made it very clear how everything fits. Magic, working with spirits, demons, angels, currents, etc, isn’t meant to be THE answer. Our spirits are far more powerful than any goetic spirit, than any angel, if we allow it to become that. If we utilize these spirits to help teach us how they transmute properties to bring about desired results, if we ask them to teach us how to strengthen our spirits, our resolve, our wisdom and power, we become closer to them. We can do what they do. It is because we are material and astral and mental, that we are even more powerful than that which is JUST material, or JUST mental, or JUST astral. That is the trade-off for us choosing to come here. That’s literally all these spirits do (transmute), and as we are spirit, that’s a very achievable thing for us to do on our own, once we have the proper instruction.
We, like spirits, each have our strengths, our domains, and if we take the time to harness and command this, we will have mastery over ourselves and “magic”. And for those things we need help with, THAT is when we call to a spiritual counterpart to teach us, to show us, to aid us, and then we learn. Just like anything else in life - the arts, cooking, math, learning cursive, etc. As above, so below… yada yada yada.
