Mbh 12.141.2a

"'Bhishma said, "O mighty-armed one, the peace and prosperity of subjects,[425] sufficiency and seasonableness of rain, disease, death and other fears, are all dependent on the king.[426] I have no doubt also in this. O bull of Bharata's race, that Krita, Treta, Dwapara, and Kali, as regards their setting in, are all dependent on the king's conduct. When such a season of misery as has been described by thee sets in, the righteous should support life by the aid of judgment. In this connection is cited the old story of the discourse between Viswamitra and the Chandala in a hamlet inhabited by Chandalas. Towards the end of Treta and the beginning of Dwapara, a frightful drought occurred, extending over twelve years, in consequence of what the gods had ordained. At that time which was the end of Treta and the commencement of Dwapara, when the period came for many creatures superannuated by age to lay down their lives, the thousand-eyed deity of heaven poured no rain. The planet Vrihaspati began to move in a retrograde course, and Soma abandoning his own orbit, receded towards the south. Not even could a dew-drop be seen, what need then be said of clouds gathering together? The rivers all shrank into narrow streamlets. Everywhere lakes and wells and springs disappeared and lost their beauty in consequence of that order of things which the gods brought about. Water having become scarce, the places set up by charity for its distribution became desolate.[427] The Brahmanas abstained from sacrifices and recitation of the Vedas. They no longer uttered Vashats and performed other propitiatory rites. Agriculture and keep of cattle were given up. Markets and shops were abandoned. Stakes for tethering sacrificial animals disappeared. People no longer collected diverse kinds of articles for sacrifices. All festivals and amusements perished. Everywhere heaps of bones were visible and every place resounded with the shrill cries and yells of fierce creatures.
