And after that grinder of foes, the royal Kuvalaswa, had set out, accompanied by his twenty-one thousand sons all of whom were exceedingly powerful, the illustrious Lord Vishnu filled him with his own energy at the command of Utanka and impelled by the desire of benefiting the triple world and while that invincible hero was proceeding on his way and loud voice was heard in the sky repeating the words, ‘This fortunate and unslayable one will become the destroyer of Dhundhu to-day.’ And the gods began to shower upon him celestial flowers. And the celestial kettle drums began to sound their music although none played upon them. And during the march of that wise one, cool breezes began to blow and the chief of the celestials poured gentle showers wetting the dust on the roads and, O Yudhishthira, the cars of the celestials could be seen high over the spot where the mighty Asura Dhundhu was. The gods and Gandharvas and great Rishis urged by curiosity, came there to behold the encounter between Dhundhu and Kuvalaswa and, O thou of the Kuru race, filled by Narayana with his own energy, king Kuvalaswa, aided by his sons, soon surrounded that sea of sands and the king ordered that wilderness to be excavated and after the king’s sons had excavated that sea of sands for seven days, they could see the mighty Asura Dhundhu. And, O bull of the Bharata race, the huge body of that Asura lay within those sands, effulgent in its own energy like the Sun himself. And Dhundhu, O king, was lying covering the western region of the desert and surrounded on all sides by the sons of Kuvalaswa, the Danava was assaulted with sharp-pointed shafts and maces and heavy and short clubs and axes and clubs, with iron spikes and darts and bright and keen-edged swords, and thus assaulted, the mighty Danava rose from his recumbent posture in wrath.
