A Satanist is an individual who practices Devil-worship, which is the worship of Satan or other demons. This practice is often associated with occultism and is sometimes seen as a form of religious expression. Satanists may also be involved in activities such as ritualistic magic, divination, and the use of symbols and artifacts related to the Devil. Satanists may also believe in the existence of a spiritual realm and may seek to gain power and influence through their worship of the Devil.
