Matsya-avatāra: The Lord as Fish Saves the Vedas and Guides Satyavrata
तत्र राजऋषि: कश्चिन्नाम्ना सत्यव्रतो महान् । नारायणपरोऽतपत् तप: स सलिलाशन: ॥ १० ॥
tatra rāja-ṛṣiḥ kaścin nāmnā satyavrato mahān nārāyaṇa-paro ’tapat tapaḥ sa salilāśanaḥ
Durante o Cākṣuṣa-manvantara houve um grande rei-sábio chamado Satyavrata. Devoto inteiramente dedicado a Nārāyaṇa, ele praticou austeridades subsistindo apenas de água.
The Lord assumed one fish incarnation to save the Vedas at the beginning of the Svāyambhuva-manvantara, and at the end of the Cākṣuṣa-manvantara the Lord again assumed the form of a fish just to favor the great king named Satyavrata. As there were two incarnations of Varāha, there were also two incarnations of fish. The Lord appeared as one fish incarnation to save the Vedas by killing Hayagrīva, and He assumed the other fish incarnation to show favor to King Satyavrata.
Satyavrata is described here as a great rājarṣi (royal sage) who was exclusively devoted to Nārāyaṇa and engaged in intense austerities, living only on water.
It means being wholly dedicated to Nārāyaṇa—making the Lord one’s supreme goal and shelter, above all other aims.
It teaches steadiness and simplicity: adopt regulated self-discipline (tapasya) and keep devotion to the Lord as the central priority, even while living in the world.
