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 to spot a rat in the temple. During the time of aarti, these rats are offered sweets, grains, etc by the devotees.
