According to Hindu Mythology, King Mahabali was the grandson of Bhaktha Prahlada, Son of demon King Hiranyakashipu. Mahabali won a battle with Lord Indra and began ruling the whole world. Though he was a demon king filled with ego and pride to the brim, he was very generous. When Mahabali was performing a yagna, He announced that he would grant anyone any request appeared in the form of a diminutive Brahman in one of the yagnas of Mahabali and asked for three paces of land as Biksha. When Mahabali agreed, Lord grew into a size of a giant and measured Heaven and earth plane in two strides, when Mahabali realised that the dwarf was Lord Vishnu, he offered his head as the third place to occupy. This subdued the ego, arrogance and pride of King Mahabali. Since the king offered his head for the Lord to step on out of devotion, Vishnu granted him a boon, that Mahabali could visit the lands and people he ruled once every year. This revisit marks the festival of Onam.
