Burmese folk religion
These exorcists, or "ahletan hsaya", are said to possess powers that can fend away or challenge these evil demons. These exorcists were often seen as very holy, because they had to be to combat troublesome spirits. They attempt exorcisms by giving the nat offerings. As an interesting overlap with Buddhism, exorcisms can be performed by holding the Buddha up to the possessed person, in an effort to have the Nat flee. If the exorcist cannot banish this spirit alone, they often ask for the assistance of the nat-kadaw. Sorcerers, or "weikzas" also harnessed the power of these nats through many complex rituals, to gain their own supernatural powers.
Exorcism in Christianity
The Catholic Church revised the Rite of Exorcism in January 1999, though the traditional Rite of Exorcism in Latin is allowed as an option. The act of exorcism is considered to be an incredibly dangerous spiritual task. The ritual assumes that possessed persons retain their free will, though the demon may hold control over their physical body, and involves prayers, blessings, and invocations with the use of the document "Of Exorcisms and Certain Supplications". In the modern era, Catholic bishops rarely authorize exorcisms, approaching would-be cases with the presumption that mental or physical illness is more likely.
