Mbh 3.101.1b

And at these roars of his, the earth, the directions, the firmament, heaven, and the mountains all began to tremble. And the chief of the celestials, deeply agitated on hearing that fierce and loud roar, was filled with fear, and desiring to slay the Asura soon, hurled, O king, the mighty Vajra. And struck with Indra’s Vajra the great Asura decked in gold and garlands fell head-long, like the great mountain Mandara hurled of yore from Vishnu’s hands; and although the prince of Daityas was slain, yet Sakra in panic ran from the field, desiring to take shelter in a lake, thinking that the Vajra itself had not been hurled from his hands and regarding that Vritra himself was still alive. The celestials, however, and the great Rishis became filled with joy, and all of them began to cheerfully chant the praise of Indra. And mustering together, the celestials began to slay the Danavas, who were dejected at the death of their leader. And struck with panic at sight of the assembled celestial host, the afflicted Danavas fled to the depths of the sea. And having entered the fathomless deep, teeming with fishes and crocodiles, the Danavas assembled together and began to proudly conspire for the destruction of the three worlds. And some amongst them that were wise in inferences suggested courses of action, each according to his judgment. In course of time, however, the dreadful resolution arrived at those conspiring sons of Diti, was that they should, first of all, compass the destruction of all persons possessed of knowledge and ascetic virtue. The worlds are all supported by asceticism. Therefore, they said, ‘Lose no time for the destruction of asceticism. Compass ye without delay the destruction of those on earth that are possessed of ascetic virtues, that are conversant with duties and the ways of morality, and that have a knowledge of Brahma; for when these are destroyed, the universe itself will be destroyed.’
