An exorcist is a person, often a religious figure, who is trained to perform an exorcism, a ritual intended to remove evil spirits or demons from a person or place. This practice is commonly associated with various religions, including Christianity, Islam, and Hinduism, each having its own methods and beliefs regarding possession and spiritual cleansing. Exorcists typically use prayers, holy water, and sacred objects during the ritual. The belief in possession and the need for exorcism varies widely across cultures and religions, with some viewing it as a psychological issue rather than a spiritual one. The role of an exorcist can be controversial, often sparking debates about faith, mental health, and the nature of evil.
