12.202.21

vinanāda mahānādaṃ kṣobhayandaityadānavān |
saṃnāditā yena lokāḥ sarvāścaiva diśo daśa || 21 ||

Endued with boons, and possessed of might, and swelling with pride, those senseless wretches do not know that Vishnu of invisible form, that God incapable of being vanquished by the very deities all acting together, hath assumed the form of a boar. That Supreme Deity, rushing to the spot whither those wretches among Danavas, of terrible aspect, are dwelling in thousands below the earth, will slay them all.' Hearing these words of the Grandsire, foremost ones among the deities felt great joy. Sometime after, Vishnu those of mighty energy, encased in the form of a Boar, penetrating into the nether regions, rushed against those offspring of Diti. Beholding that extraordinary creature, all the Daityas, uniting together and stupefied by Time, quickly proceeded against it for exerting their strength, and stood surrounding it. Soon after, they all rushed against that Boar and seized it simultaneously. Filled with rage they endeavoured to drag the animal from every side. Those foremost of Danavas, of huge bodies, possessed of mighty energy, swelling with strength, succeeded not, however, O monarch, in doing anything to that Boar. At this they wondered much and then became filled with fear. Numbering in thousands, they regarded that their last hour had come. Then that Supreme God of all the gods, having yoga for his soul and yoga for his companion, became rapt in yoga, O chief of the Bharatas, and began to utter tremendous roars, agitating those Daityas and Danavas.

All the worlds and the ten points of the compass resounded with those roars, which, for this reason, agitated all creatures and filled them with fear. The very gods with Indra at their head became terror-stricken. The whole universe became stilled in consequence of that sound. It was a dreadful time. All mobile and immobile beings became stupefied by that sound. The Danavas, terrified by that sound, began to fall down lifeless, paralysed by the energy of Vishnu. The Boar, with its hoofs, began to pierce those enemies of the gods, those denizens of the nether regions, and tear their flesh, fat, and bones. In consequence of those tremendous roars, Vishnu came to be called by the name of Sanatana. He is also called Padmanabha. He is the foremost of yogins. He is the Preceptor of all creatures, and their supreme Lord. All the tribes of the gods then repaired to the Grandsire. Arrived at the presence, those illustrious ones a dressed the Lord of the universe, saying, 'What sort of a noise is this, O puissant one? We do not understand it. Who is this one, or whose is this sound at which the universe hath been stupefied? With the energy of this sound or of its maker, the gods and the Danavas have all been deprived of their senses.' Meanwhile, O mighty-armed one, Vishnu in his porcine form was in sight of the assembled gods, his praises hymned by the great Rishis.'
