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.
The Exorcist
The Exorcist is a 1973 American supernatural horror film directed by William Friedkin, adapted by William Peter Blatty from his 1971 novel of the same name, and starring Ellen Burstyn, Linda Blair, Max von Sydow, and Jason Miller. The film is part of "The Exorcist" franchise. The book, inspired by the 1949 exorcism of Roland Doe, deals with the demonic possession of a 12-year-old girl and her mother's attempts to win back her child through an exorcism conducted by two priests. The adaptation is relatively faithful to the book, which itself has been commercially successful (hitting the "New York Times" bestseller list).
