Chaos magick, the way I've come to see it is not abiding to a single way of belief, kind of like hermetics would do. More like using various things from various schools to get what you want, keeping in mind that the meaning the things carry or their origins matter little if you can still put your all into it. Example: those people who call themselves Jedi and use the Force as a medium to channel their magic (not talking about the delusional fanboys)
