When the demon Hiranyaksha tormented the earth (personified as the goddess Bhudevi) and its inhabitants, she sinked into the primordial waters. Vishnu took the form of the Varaha and descended into the depths of the oceans to rescue her. Varaha slew the demon and retrieved the Earth from the ocean, lifting her on his tusks, and restored Bhudevi to her place in the universe.
The rescued earth lifted by Varaha is often depicted as a young woman called Bhudevi. The earth may also be depicted as a mass of land balanced on his tusk.
