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
The leaders of the exorcisms create a dramatic performance to call out the demons so the village can once again have peace. The leaders strike themselves with a sharp weapon so they bleed. Blood is considered to be a protector, so after the rituals, the blood is blotted with a tissue and put on the door of houses as an act of protection against evil spirits.
