The Karni Mata temple, Deshnok is situated 30 km from Bikaner. The temple is dedicated to an early 15th century mystic, considered to be a reincarnation of Goddess Durga. This temple is quite famous for a large number of brown rats running around the temple complex fearlessly. It is believed that the souls of dead Charans (traditional bards, the devotees of Mata) reside in these rats.
It is considered very lucky seeing a white rat or when a rat runs over your foot.During the time of aarti, these rats are offered sweets, grains, etc by the devotees.The thing which strikes everyone with wonder is the presence of thousands and thousands of rats in the temple which freely moved about unscared of anyone Despite the presence of the pilgrims in great numbers.

There was no incidence of plague at all. People deem this as an miracle of Karanimata. In the whole world this is a unique temple where rats freely move out.
