Bhudevi or the goddess Earth is known in Rgveda as Prithivi and is praised in several hymns mainly in reverence for her awesome stability and apparently inexhaustible fecundity. In Brahmana literature, she is described as the goddess created by Prajapati as a result of his austerity and immense energy. Later she became an important aspect of Vaishnava mythology. Whenever Bhudevi is oppressed by a certain demon, Vishnu, attentive to the welfare of the earth, assumes the appropriate form like Varaha and rescues the Earth from her predicament. Iconographically, it is also common to see Vishnu flanked by Shridevi on one side and Bhudevi on the other.
