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. And when the end of the Yuga comes, everybody will be in want. And all the points of the horizon will be ablaze, and the stars and stellar groups will be destitute of brilliancy, and the planets and planetary conjunctions will be inauspicious. And the course of the winds will be confused and agitated, and innumerable meteors will flash through the sky, foreboding evil. And the Sun will appear with six others of the same kind. And all around there will be din and uproar, and everywhere there will be conflagrations. And the Sun, from the hour of his rising to that of setting, will be enveloped by Rahu. And the deity of a thousand eyes will shower rain unseasonably. And when the end of the Yuga comes, crops will not grow in abundance. And the women will always be sharp in speech and pitiless and fond of weeping. And they will never abide by the commands of their husbands. And when the end of the Yuga comes, sons will slay fathers and mothers. And women, living uncontrolled, will slay their husbands and sons. And, O king, when the end of the Yuga comes, Rahu will swallow the Sun unseasonably. And fires will blaze up on all sides. And travellers unable to obtain food and drink and shelter even when they ask for these, will lie down on the wayside refraining from urging their solicitations. And when the end of the Yuga comes, crows and snakes and vultures and kites and other animals and birds will utter frightful and dissonant cries. And when the end of the Yuga comes, men will cast away and neglect their friends and relatives and attendants. And, O monarch, when the end of the Yuga comes, men abandoning the countries and directions and towns and cities of their occupation, will seek for new ones, one after another.
