The Karni Mata temple in Bikaner, India is dedicated to a mystic who was believed to be the avatar of the goddess Durga - the temple is full of rats, it is believed that the rats will be reincarnated as holy men so the worshippers feed and care for the rats. It is considered good luck to have a rat run over you. There are a scant few albino rats in the temple, they are believed to be the future incarnation of the mystics.
The story goes something like: a woman brought her recently deceased son to Karni Mata, but the God of Death said her son had already chosen a new reincarnated form and could not be recalled to his old body. Karni refused to accept it, and ever after her tribe of people would automatically be reincarnated as rats, and when the rats died, they would be reborn back into the same tribe again instead of choosing a random form. Hindu stories are so fascinating.
