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.
Exorcist
In some religions, an exorcist (from the Greek „εξορκιστής“) is a person who is believed to be able to cast out the devil or other demons. A priest, a nun, a monk, a healer, a shaman or other specially prepared or instructed person can be an exorcist. An exorcist is a person who performs the ridding of demons or other supernatural beings who are alleged to have possessed a person, or (sometimes) a building or even an object.
