1.22.3

saṃghātitamivākāśaṃ jaladaiḥ sumahādbhutaiḥ |
sṛjadbhiratulaṃ toyamajasraṃ sumahāravaiḥ || 3 ||

"Sauti said, 'And then Indra, the king of gods, having the best of horses for his bearer, thus adored by Kadru, covered the entire firmament with masses of blue clouds. And he commanded the clouds, saying, Pour ye, your vivifying and blessed drops!' And those clouds, luminous with lightning, and incessantly roaring against each other in the welkin, poured abundant water. And the sky, in consequence of those wonderful and terribly-roaring clouds that were incessantly begetting vast quantities of water, looked as if the end of Yuga had come. And in consequence of the myriads of waves caused in the falling torrents, the deep roar of the clouds, the flashes of lightning, the violence of the wind, and the general agitation, the sky looked as if dancing in madness. The sky became overcast, and the rays of the Sun and the Moon totally disappeared in consequence of that incessant downpour.
