I found this description of a Russion exorcism on the Onelargeprawn blog.
In May 1st 2004, Eugene Safronov, an assistant to one of the exorcists in the Russian Orthodox Church, made a chilling recording of an actual exorcism that he bore witness to. A 16-year old girl is being held down in a chair by her mother whilst a priest stands over her reading the rite of exorcism. As he proceeds, the girl starts to struggle as if the priest’s words are burning her.
The girl struggles violently, her groans becoming inhuman howls and deep, guttural moans of psychological pain. Then she lashes out at the priest, and in a voice that seems not to be her own, spits words of defiance.
I didn’t listen to the recording because of bandwidth caps, and anyway there are no speakers connected to my computer, but if anyone who speaks Russian is reading this, I’d be interested in their response — you’ll have to go to the Onelargeprawn blog to listen, though.
