who was defeated by vaman avatar of vishnu
Vamana Vamana (Sanskrit: वामन, IAST: Vāmana, lit. dwarf), is the fifth avatar of Hindu god Vishnu.[1][2] He incarnates in a time of crisis to restore cosmic balance by creatively defeating the Asura king Mahabali, who had acquired disproportionate power over the universe. According to Hindu mythology, the noble demon king sponsors a sacrifice and gift giving ceremony to consolidate his power, and Vishnu appears at this ceremony as a dwarf mendicant Brahmin called Vamana.[1] When Vamana's turn comes to receive a gift, Mahabali offers him whatever riches and material wealth he would like, but Vamana refuses everything and states he would just like three paces of land. Mahabali finds the dwarf's request amusingly small and irrevocably grants it.[1] Vamana then grows into a giant of cosmic proportions. In one step he covers the earth, in another the heavens, and for the third, Mahabali offers his head on which Vamana steps, sending the demon king to the Patala (netherworld).[1][3]
