Magic is something people practice all the time whether they are conscious of it or not. Once we become aware of the existence of causes and effects in the Universe, we can dance and sing along with the cosmos. Fate lays down the rhythm while freewill improvises the lead.
ChironJackal, Thanks. Yes, I've read plenty of Crowley. I suggested Prometheus Rising because I use it as a reference quite often, and it is part of the basis of magic that I practice. Also, anything by Jung.
