What is the Indian myth system?

In the14th century, there was a Hindu priestess named KarniMata Karnimata (that is, the mouse goddess enshrined in this temple). This priestess was the incarnation of the goddess' inaccessible mother (the mother of the elephant god and the wife of Shiva). One day, one of her children died, and the mother of the child came to Karnimata with her dead son in her arms, hoping to bring her son back to life. Karni Marta KarniMata immediately went to the underworld to seek the theory of death YAMARAJA, but death refused her request because the child's soul had been reincarnated into other animals. In a rage, Karnimata announced that all members of his family would be reincarnated as rats immediately after death (from Indian reincarnation theory), until the dead children could be reincarnated as rats, born in her family and continue to be family members. Living people built temples for these mice in order not to let the souls of their relatives hide and wander around on the ground, because they believed that the mice that wandered freely in the temples were their dead relatives, and they also believed that they would report to this temple as mice after they died. It is said that among the thousands of mice in the temple, five white mice are particularly sacred. They are the embodiment of Karni Marta and her four sons (so it is very lucky to see white mice in the mouse temple).
