About Vamana, the Lord Vishnu's incarnation
Lord Vamana is an important figure in Hinduism and is considered the fifth incarnation of Lord Vishnu. The term "Vamana" means "dwarf" in Sanskrit. According to legend, Lord Vishnu took this form to defeat the demon King Mahabali. To humble the arrogant King Mahabali, Vamana took on the appearance of a small Brahmin boy and approached the demon king. He requested three paces of land from Bali. Initially, King Bali mocked him, but with his first two steps, Vamana covered the entire universe. With his third step, he pushed Bali down to the netherworld. This act restored heaven, and Bali was granted the boon to rule over the netherworld.
