Chaos magick.. The more reading i do, the more I'm convinced I already practice it.
I use a wide variety of techniques depending on my goals.
My ritual structure is heavily influenced by wicca/neopaganism, with qahbalah-like symbols, often doing the base of the ritual in Hebrew (or, whatever phrase of untraceable origin pops in my head. Strangely, often hebrew. I don't even know Hebrew.), and often scrying/summoning a Wendish Slavic diety I feel a strange connection to. Not that Zirnitra is more real than Zeus, Anubis, Yahweh, or Hecate, just that He synergizes well with me and my goals. I do use others fairly often.
I often meditate on the All, or the Universe, or Shamanic spirits of individual plants or species.
I also use saltpetre and sugar to good effect in dramatic rituals. Did I mention I'm a bit of a pyro?
