“In Hindu folklore, the vetala is an evil spirit who haunts cemeteries and takes demonic possession of corpses. They make their displeasure known by troubling humans. They can drive people mad, kill children, and cause miscarriages, but on the other hand, also guard villages.
They are hostile spirits of the dead trapped in the ‘twilight zone’ between life and afterlife. These creatures can be repelled by the chanting of mantras. One can free them from their ghostly existence by performing their funerary rites. Being unaffected by the laws of space and time, they have an uncanny knowledge about the past, present, and future and a deep insight into human nature. Therefore many sorcerers seek to capture them and turn them into slaves.”
