Mbh 3.189.3f

And Sudras will expound the scriptures, and Brahmanas will wait upon and listen to them, and settle their course of duty accepting such interpretations as their guides. And the low will become the high, and the course of things will look contrary. And renouncing the gods, men will worship bones and other relics deposited within walls. And, at the end of the Yuga, the Sudras will cease to wait upon and serve the Brahmanas. And in the asylums of great Rishis, and the teaching institutions of Brahmanas, and in places sacred to the gods and sacrificial compounds, and in sacred tanks, the earth will be disfigured with tombs and pillars containing bony relics and not graced with temples dedicated to the gods. All this will take place at the end of the Yuga, and know that these are the signs of the end of the Yuga. And when men become fierce and destitute of virtue and carnivorous and addicted to intoxicating drinks, then doth the Yuga come to an end. And, O monarch, when flowers will be begot within flowers, and fruits within fruits, then will the Yuga come to an end. And the clouds will pour rain unseasonably when the end of the Yuga approaches. And, at that time, ceremonial rites of men will not follow one another in due order, and the Sudras will quarrel with the Brahmanas. And the earth will soon be full of mlecchas, and the Brahmanas will fly in all directions for fear of the burthen of taxes. And all distinctions between men will cease as regards conduct and behaviour, and afflicted with honorary tasks and offices, people will fly to woody retreats, subsisting on fruits and roots. And the world will be so afflicted, that rectitude of conduct will cease to be exhibited anywhere. And disciples will set at naught the instructions of preceptors, and seek even to injure them. And preceptors impoverished will be disregarded by men. And friends and relatives and kinsmen will perform friendly offices for the sake of the wealth only that is possessed by a person.
