Hindu King of Ghosts
According to the Hindu faith, selfish thinking causes negative actions and increased bad karma, and there’s one god fit to rein in the evil: Vetal, the King of Ghosts. Tasked with restoring buddhi, or wisdom, in the world, Vetal is basically a cleaner for the evil within humans as they navigate the earthly sphere.
Aravali, a village in the region of Konkan, has taken Vetoba (the physical manifestation of Vetal) as its own god, and long ago erected the Vetoba Temple as more or less a place to pay homage to Ghost King himself in iconic form.
