Mbh 3.270.1e

O king of Sindhu, hast thou not heard of the wonderful achievements of Vishnu, described to thee by the Munis and the Brahmanas learned in the Vedas? When the world was thus reduced to one vast sea of water, with only the heavens above, the Lord, like a fire-fly at night-time during the rainy season, moved about hither and thither in search of stable ground, with the view of rehabilitating his creation, and became desirous of raising the Earth submerged in water. What shape shall I take to rescue the Earth from this flood?--So thinking and contemplating with divine insight, he bethought himself of the shape of a wild boar fond of sporting in water. And assuming the shape of a sacrificial boar shining with effulgence and instinct with the Vedas and ten Yojanas in length, with pointed tusks and a complexion like dark clouds, and with a body huge as a mountain, and roaring like a conglomeration of clouds, the Lord plunged into the waters, and lifted up the Earth with one of his tusks, and replaced it in its proper sphere. At another time, the mighty Lord, assuming a wonderful form with a body half lion, half man, and squeezing his hands, repaired to the court of the ruler of the Daityas. That progenitor of the Daityas, the son of Diti, who was the enemy of the (gods), beholding the Lord’s peculiar form, burst out into passion and his eyes became inflamed with rage. And Hiranya-Kasipu, the war-like son of Diti and the enemy of the gods, adorned with garlands and looking like a mass of dark clouds, taking up his trident in hand and roaring like the clouds, rushed on that being half lion, half man. Then that powerful king of wild beasts, half man, half lion, taking a leap in the air, instantly rent the Daitya in twain by means of his sharp claws. And the adorable lotus-eyed Lord of great effulgence, having thus slain the Daitya king for the well-being of all creatures, again took his birth in the womb of Aditi as son of Kasyapa.
