Exorcism
In Catholic practice the person performing the exorcism, known as an exorcist, is an ordained priest. The exorcist recites prayers according to the rubrics of the rite, and may make use of religious materials such as icons and sacramentals. The exorcist invokes God—specifically the Name of Jesus—as well as members of the Church Triumphant and the Archangel Michael to intervene with the exorcism. According to Catholic understanding, several weekly exorcisms over many years are sometimes required to expel a deeply entrenched demon.
Exorcism
Beliefs and practices pertaining to the practice of exorcism are prominently connected with Hindus. Of the four Vedas (holy books of the Hindus), the Atharva Veda is said to contain the secrets related to exorcism, magic and alchemy.
The basic means of exorcism are the "mantra" and the "yajna" used in both Vedic and Tantric traditions. Vaishnava traditions also employ a recitation of names of Narasimha and reading scriptures, notably the "Bhagavata Purana" aloud.
