Term: Ad Libitum

Latin for “at one’s pleasure,” it means to make things up as you go. Once you know the basic concepts of rituals and magick, it is possible to make up parts of rituals “on the fly” rather than depending upon repeating memorized scripts or reading written instructions. Often shortened to “ad lib.”
