This is a non-theistic form of magic. I do not discount the existence of Gods or spirits, and I long practiced forms of magic which call upon them. I have simply found that they are not necessary in the paradigms of that I have found to produce the best results for me. One of the comments that is occasionally made about my work is that I am too mired in a materialist worldview, and that I am somehow against the inherent mysticism and wonder that are a part of practicing magic. I can assert from my point of view that this is not the case. I simply find this wonder in the structure and behavior of the universe itself, and the contemplation of how a conscious mind can interface with it to perform these acts of wonder.
Existence is absurd, but that doesn't mean it can't be appreciated. More importantly, it can be influenced.
