Saligrama

Shila, (शिला in Devanagari, śila in IAST refers to a Vaishnava (Hindu) aniconic representation of Vishnu, in the form of a spherical, usually black-coloured fossil found in the sacred river Gandaki. They are more often referred to as Shaligram Shilas, with Shila being the shortened version. The word Shila translates simply to 'stone' and Shaligram is a less well-known name of Vishnu. The origin of the name is traced to a remote village in Nepal where Vishnu is known by the name of Shaligraman. Shaligram in Hinduism is also known as Salagrama. The name Salagrama refers to the name of the village on the bank of Gandaki where the holy stones are picked up. The name is derived from the hut (sala) of the sage Salankayana, who beheld the form of Vishnu in a tree outside his hut (cf. Varaha-purana). This hut was on the banks of the Gandaki, and it was in that particular spot that these sacred stones were found in abundance. The stones were therefore called Salagrama.
