Sanskrit Original
हंसस्वरूप्यवददच्युत आत्मयोगं दत्त: कुमार ऋषभो भगवान् पिता न: । विष्णु: शिवाय जगतां कलयावतीर्ण- स्तेनाहृता मधुभिदा श्रुतयोहयास्ये ॥ १७ ॥
haṁsa-svarūpy avadad acyuta ātma-yogaṁ dattaḥ kumāra ṛṣabho bhagavān pitā naḥ viṣṇuḥ śivāya jagatāṁ kalayāvatīrṇas tenāhṛtā madhu-bhidā śrutayo hayāsye
The infallible Supreme Personality of Godhead, Viṣṇu, has descended into this world by His various partial incarnations such as Lord Haṁsa [the swan], Dattātreya, the four Kumāras and our own father, the mighty Ṛṣabhadeva. By such incarnations, the Lord teaches the science of self-realization for the benefit of the whole universe. In His appearance as Hayagrīva He killed the demon Madhu and thus brought the Vedas back from the hellish planet Pātālaloka.
