Mbh 12.224.4c

Some have said that Brahma is Fire; some that he is Prajapati; some that he is the Seasons; some that he is the Month; some that he is the Fortnight; some that he is the Days; some that he is the Hours; some that he is the Morning; some that he is the Noon; some that he is the Evening; and some that he is the Moment. Thus diverse people speak diversely of him who is single. Know that he is Eternity, under whose sway are all things. Many thousands of Indras have passed away, O Vasava, each of whom was possessed of great strength and prowess. Thou also, O lord of Sachi, shalt have to pass away after the same manner. Thee, too, O Sakra, that art possessed of swelling might and that art the chief of the deities, when thy hour comes, all-powerful Time will extinguish! Time sweeps away all things. For this reason, O Indra, do not brag. Time is incapable of being quieted by either thee or me or by those gone before us. This regal prosperity that thou hast attained and that thou thinkest to be beyond comparison, had formerly been possessed by me. It is unsubstantial and unreal. She does not dwell long in one place. Indeed, she had dwelt in thousands of Indras before thee, all of whom, again, were very much superior to thee. Unstable as she is, deserting me she hath now approached thee, O chief of the deities! Do not, O Sakra, indulge in such brag again. It behoveth thee to become tranquil. Knowing thee to be full of vanity, she will very soon desert thee.'"'"
