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.
Lewis Ashmore
Ashmore was a noted exorcist having performed hundreds of exorcisms since the 1950s. "For decades Rev. Lewis Ashmore cast out devils during tent revivals in the Central Valley. People foamed at the mouth, talked back to him in a strange voice and writhed uncontrollably on the ground." Aged 75, two years before he died, Ashmore concluded that demonic possession could be explained in the 21st century by modern medicine. "Back in Christ’s day, these mental conditions weren’t yet diagnosed,” he said. “All exorcisms can be explained by psychology and science."
