I know about Gorakhpur. The baba who buried himself and claimed he will come out alive after seven days. When dug up after seven days, his dead body was found with his tongue sticking out and bad smell from flesh decay came from the pit. Gorakhpur is one of the most backward and 'blind-faith' areas of India. Pilot Baba, Khadeshwari Baba, Karpaatri Baba and many such babas have a field day there in Eastern UP.
