Mbh 3.187.3b

And, O king, the clouds that gather in the sky on the occasion are terrible to behold and wreathed with lightnings, roar frightfully. And those vapoury masses, charged with rain, soon cover the entire welkin. And, O king, those masses of vapour then flood with water the whole earth with her mountains and forests and mines. And, O bull among men, urged by the Supreme Lord those clouds roaring frightfully, soon flood over the entire surface of the earth. And pouring in a great quantity of water and filling the whole earth, they quench that terrible inauspicious fire (of which I have already spoken to thee). And urged by the illustrious Lord those clouds filling the earth with their downpour shower incessantly for twelve years. And then, O Bharata, the Ocean oversteps his continents, the mountains sunder in fragments, and the Earth sinks under the increasing flood. And then moved on a sudden by the impetus of the wind, those clouds wander along the entire expanse of the firmament and disappear from the view. And then, O ruler of men, the Self-create Lord--the first Cause of everything--having his abode in the lotus, drinketh those terrible winds and goeth to sleep, O Bharata!
