Emotion is the power that drives the whole show; emotion from the guts, and from the heart. I will go even further; it is not just emotion, but passion that is the power behind magick. Passion in the sense of an intense desire to be connected to that which you are seeking to invoke; a desire that places no restrictions or limits on the connection, but which is so one-pointed that nothing save that which is sought is included within its focus. And passion in the sense of a boundless enthusiasm for the acts by which you seek to create that connection. Admittedly, this is the ideal case; but the closer you can get to it, even for a few moments, the more likely your work is to be successful.
