Indian Zombies

An animated corpse resurrected by mystical means such as witchcraft

This is how wikipedia describes a zombie. Like vampires and werewolves, they are a fairly common subject in the movie and gaming world. And unlike other such creatures they are never ever shown in positive light. 

Zombies have generally not been depicted in the Indian context. But all of a sudden there is a spate of zombie related Hindi movies coming up. In fact, in the trailer of "Go Goa Gone", when one character asks  how did zombies come into India, globalization is the answer he gets.

Now the question on why aren't there such "undead" creatures in Indian folklore? Ghosts, spirits, djinns, apparitions, witches, magicians are fairly common in Indian folklore but there is hardly any mention of things which are undead. Maybe because of Indian tradition of cremation of dead bodies rather than burials.As the dead bodies tended to be completely destroyed, hence the likelihood of a corpse being resurrected becomes  very rare. Hence no such things as zombies as part of Indian folklore.

This is just my theory. Any other takes?
