Jaleshwor literally means God of water because of the Shiva Linga situated under the surface of the water. Located in Mahottari district of central terai region of the country, it is said that about 250 years ago, a hermit named Jagadesh had visited this place and had meditated. He then made a prophecy that the soil of this place would crack and Shiva Linga would emerge. Because of this belief, even today, the ritual of offering food to the hermit Jagadesh takes place in the month of Mangsir (November/December), of each year and his Shraddha is performed. During the Shivaratri festival, great religious gatherings take place at this temple.
