According to the legend, the wedding of Lord Shiva and Parvathi in Varanasi caused a change in the Earth's rotation because of the crowd of all Gods and Goddesses. Lord Shiva requested sage Agastya to restore the balance of earth by traveling towards the south.

Sage Agasthya expressed his wish to witness the wedding of Lord Shiva and Parvathi. Lord Shiva assured to grant divine vision to the sage, which would enable him to witness the wedding from any part of the world.

Sage Agasthya then traveled towards the south and resided in Kalasa from where he watched the wedding of Lord Shiva. The Girija Kalyana is celebrated in the temple of Kalasa every year to honor this tradition.

Local legends state that a pilgrimage to Kalasa brings greater religious merit than a visit to Varanasi. The pilgrim to arrive here will visit Kalaseshwara temple and offer prayer to Lord Kalaseshwara.
