LaVey emphasized that in his tradition, Satanic rites came in two forms, neither of which were acts of worship; in his terminology, "rituals" were intended to bring about change, whereas "ceremonies" celebrated a particular occasion. These rituals were often considered to be magical acts, with LaVey's Satanism encouraging the practice of magic to aid one's selfish ends. Much of LaVeyan ritual is designed for an individual to carry out alone; this is because concentration is seen as key to performing magical acts. In "The Satanic Bible", LaVey described three types of ritual in his religion: sex rituals designed to attract the desired romantic or sexual partner, compassionate rituals with the intent of helping people (including oneself), and destructive magic which seeks to do harm to others. In designing these rituals, LaVey drew upon a variety of older sources, with scholar of Satanism Per Faxneld noting that LaVey "assembled rituals from a hodgepodge of historical sources, literary as well as esoteric".
