Mbh 1.219.3

“Vaisampayana continued, ‘Thus addressed, that Brahmana of virtuous soul and good deeds and equal in splendour, O hero, unto the sun or the moon, became propitious unto them. And the Brahmana said, ‘The words hundred and hundred thousand are all indicative of eternity. The word hundred, however, as employed by me is to be understood as a limited period and not indicative of a period without end. Ye shall, therefore, becoming crocodiles, seize and take away men (for only a hundred years as explained by me). At the end of that period, an exalted individual will drag you all from water to the land. Then ye will resume your real forms. Never have I spoken an untruth even in jest. Therefore, all that I have said must come to pass. And those sacred waters (within which I assign you your places), will, after you will have been delivered by that individual, become known all over the world by the name of Nari-tirthas (or sacred waters connected with the sufferings and the deliverance of females), and all of them shall become sacred and sin cleansing in the eyes of the virtuous and the wise.’
