Nara-Nārāyaṇa Ṛṣi and the Lord’s Unlimited Incarnations
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.
It is stated in the Skanda Purāṇa that the Lord of the universe, Hari Himself, once appeared in the form of a young brahmacārī named Kumāra and spoke transcendental knowledge to Sanat-kumāra.
This verse states that Madhusūdana (the Lord) restored the stolen śrutis (Vedas) by appearing in His Hayagrīva (horse-faced) form, protecting revealed knowledge for the world.
He is listing the Lord’s compassionate descents that teach ātma-yoga and spiritual wisdom—different avatāras and empowered forms through whom the same Supreme Lord guides the world toward liberation.
Treat spiritual practice as learning the ‘science of the Self’: study authentic śāstra, cultivate detachment and inner discipline, and rely on the Lord’s guidance—seeing Him as the source and protector of true knowledge.
