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
The office of Exorcist was not a part of the sacrament of Holy Orders but as a sacramental was instead first conferred on those who had the special charism to perform its duties and later to those studying for the priesthood. By the twentieth century, the order had become purely ceremonial. As a minor order, exorcists wore the surplice.
