Ghost fair to scare away evil spirits

From New India Express of Chennai, India:

GAYA: At a time when people across the country and world are relying upon the ultra-modern medical facilities for their health problems, people living in some rural pockets of the Bihar still believe in magical powers and evil spirits. In one such instance, hundreds of people thronged a Ghost fair, in a non-descript village in Gaya and offered prayers at the shrine of a Hazrat Sayal Khayal Kutram Tulla, a Muslim saint, whose 'super natural' powers are believed to rid people from the grip of ghosts and evil spirits.

I'm at the point I'm ready to blame evil spirits for my allergy problems.
