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 in the Catholic Church
In the process of an exorcism the person possessed may be restrained so that they do not harm themselves or any person present. The exorcist then prays and commands for the demons to retreat. The Catholic Priest recites certain prayers the Our Father, Hail Mary, and the Athanasian Creed. Exorcists follow procedures listed in the ritual of the exorcism revised by the Vatican in 1999. Seasoned exorcists use the Rituale Romanum as a starting point, not always following the prescribed formula exactly. "The Gale Encyclopedia of the Unusual and Unexplained" describes that an exorcism was a confrontation and not simply a prayer and once it has begun it has to finish no matter how long it takes. If the exorcist stops the rite, then the demon will pursue him which is why the process being finished is so essential. After the exorcism has been finished the person possessed feels a “kind of release of guilt and feels reborn and freed of sin.” Not all exorcisms are successful the first time; it could take days, weeks, or months of constant prayer and exorcisms.
