It is believed that Nainital figures in some ancient myths of India. In the Manas Khand of the SkandPuranas, Nainital Lake is called Tri-Rishi-Sarovar, hinting at the story of three sages (or rishis), Atri, Pulastya and Pulaha, who, upon finding no water in Nainital, dug a large hole at the location of the present day lake (sarovar = lake) and filled it with water from the holy lake Manasarovar inTibet. According to lore, a dip in Naini Lake, "the lesser Manasarovar," earns merit equal to a dip in the great lake.
It is also believed that The Naini Lake is one of the 64 Shakti Peeths, or religious sites where parts of the charred body of Sati (Parvati) fell on earth while being carried by Lord Shiva. The spot where Sati's eyes (or Nain) fell, came to be called Nain-tal or lake of the eye. The goddess Shakti is worshipped at the Naina Devi Temple on the north shore of the present day lake.
