yamāhurajitaṃ devaṃ śaṅkhacakragadādharam |
pradhānaḥ so'straviduṣāṃ tena kṛṣṇena rakṣyate || 29 ||

[paragraph continues] He had the ascetic's staff and water-pot in hand, and was marked with the emblem of a curl of hair on the breast. And that adorable Being wore matted locks and the sacrificial thread, and he was stout and handsome and resplendent with lustre. And that Being, arriving at the sacrificial enclosure of Vali, king of the Danavas, entered the sacrificial assembly with the aid of Vrihaspati. And beholding that dwarf-bodied Being, Vali was well-pleased and said unto him, 'I am glad to see thee, O Brahmana! Say what is it that thou wantest from me!' Thus addressed by Vali, the dwarf-god replied with a smile, saying, 'So be it! Do thou, lord of the Danavas, give me three paces of ground!' And Vali contented to give what that Brahmana of infinite power had asked. And while measuring with his paces the space he sought. Hari assumed a wonderful and extraordinary form. And with only three paces he instantly covered this illimitable world. And then that everlasting God, Vishnu, gave it away unto Indra. This history which has just been related to thee, is celebrated as the 'Incarnation of the Dwarf', And from him, all the gods had their being, and after him the world is said to be Vaishnava, or pervaded by Vishnu. And for the destruction of the wicked and the preservation of religion, even He hath taken his birth among men in the race of the Yadus. And the adorable Vishnu is styled Krishna. These, O king of Sindhu, are the achievements of the Lord whom all the worlds worship and whom the learned describe as without beginning and without end, unborn and Divine! They call Him, the unconquerable Krishna with conchshell, discus and mace, and adorned with the emblem of a curl of hair, Divine, clad in silken robes of yellow hue, and the best of those versed in the art of war. Arjuna is protected by Krishna the possessor of these attributes. That glorious and lotus-eyed Being of infinite power, that slayer of hostile heroes, riding in the same chariot with Pritha's son, protecteth him! He is, therefore, invincible; the very gods cannot resist his power, still less can one with human attributes vanquish the son of Pritha in battle! Therefore, O king, thou must let him alone! Thou shalt, however, be able to vanquish for a single day only, the rest of Yudhishthira's forces along with thine enemies--the four sons of Pandu!"
