LaVey defined his system of magic as greater and lesser magic. Greater magic is a form of ritual practice and is meant as psychodramatic catharsis to focus one's emotional energy for a specific purpose. These rites are based on three major psycho-emotive themes: "compassion" (love), "destruction" (hate), and "sex" (lust). The space in which a ritual is performed is known as an "intellectual decompression chamber", where skepticism and disbelief are willfully suspended, thus allowing the magicians to fully express their mental and emotional needs, holding back nothing regarding their deepest feelings and desires. This magic could then be employed to ensure sexual gratification, material gain, personal success, or to curse one's enemies. LaVey also wrote of "the balance factor", insisting that any magical aims should be realistic. These rituals are often considered to be magical acts, with LaVey's Satanism encouraging the practice of magic to aid one's selfish ends. Much of Satanic ritual is designed for an individual to carry out alone; this is because concentration is seen as key to performing magical acts.
