Darshan

Shankhacuda, a mighty daitya, underwent a severe tapasya that pleased Brahma. He was granted the Viṣṇukavaca (the armour of Vishnu), and was blessed with another boon: As long as the Viṣṇukavaca was on his body, no one could slay him. Shankhacuda and Tulasi were soon married. His arrogance caused conflict with the devas, who petitioned Vishnu to relieve them. Vishnu granted his trishula to Shiva, who slew Shankachuda with the weapon. Vishnu appeared in the form of Shankacuda to Tulasi, and the two sported, and ceased when Tulasi realised that he was an imposter. In regional variations of this legend, Tulasi, in her anger and grief at her husband's demise, cursed Vishnu to be turned into stone. Vishnu turned into a stone, and resided on riverbank Gandaki River.
