And enraged, the Asura began to swallow those various weapons that were hurled at him and he vomited from his mouth fiery flames like unto those of the fire called Samvarta that appeareth at the end of the Yuga and by those flames of his, the Asura consumed all the sons of the king and, O tiger among men, like the Lord Kapila of old consuming the sons of king Sagara, the infuriated Asura overwhelming the triple world with the flames vomited from his mouth, achieved that wonderful feat in a moment. And, O thou best of the Bharatas, when all those sons of king Kuvalaswa were consumed by the fire emitted by the Asura in wrath, the monarch, possessed as he was of mighty energy, then approached the Danava who, like unto a second Kumbhakarna of mighty energy, had come to the encounter after waking from his slumbers. From the body of the king, O monarch, then began to flow a mighty and copious stream of water and that stream soon extinguished, O king, the fiery flames emitted by the Asura. And, O great king, the royal Kuvalaswa, filled with Yoga force, having extinguished those flames by the water that issued from his body, consumed that Daitya of wicked prowess with the celebrated weapon called Brahma for relieving the triple world of its fears, and the royal sage Kuvalaswa, having consumed that great Asura, that foe of the celestials and slayer of all enemies, by means of that weapon became like unto a second chief of the triple world and the high-souled king Kuvalaswa having slain the the Asura Dhundhu, became from that time known by the name of Dhundhumara and from that time he came to be regarded as invincible in battle, and the gods and the great Rishis who had come to witness that encounter were so far gratified with him that they addressed him saying, ‘Ask thou a boon of us!’
