The infallible Supreme Personality of Godhead, Vishnu, has descended into this world by His various partial incarnations such as Lord Hamsa [the swan], Dattatreya, the four Kumaras and our own father, the mighty Rishabhadeva. By such incarnations, the Lord teaches the science of self-realization for the benefit of the whole universe. In His appearance as Hayagriva He killed the demon Madhu and thus brought the Vedas back from the hellish planet Patalaloka.
