Mbh 5.132.2b

Indeed, it is the king that is the cause of also the fourth Yuga (viz., the Kali). That king who causeth the Krita age to set in, enjoyeth heaven exceedingly. That king who causeth the Treta age to set in, doth enjoy heaven but not exceedingly. For thus causing the Dwapara age to set in, a king enjoyeth heaven according to his due. The king, however, who causeth the Kali age to set in, earneth sin exceedingly. Thereupon, that king of wicked deeds resideth in hell for countless years. Indeed, the king’s sins affect the world, and the world’s sins affect him. Observe thou those kingly duties of thine that befit thy ancestry. That is not the conduct of a royal sage in which thou wishest to abide. Indeed, he that is stained by weakness of heart and adhereth to compassion, and is unsteady, never obtaineth the merit born of cherishing his subjects with love. That understanding according to which thou art now acting was never wished (to thee) by Pandu, or myself, or thy grandsire, while we uttered blessings on thee before; sacrifice, gift, merit, and bravery, subjects and children, greatness of soul, and might, and energy, these were always prayed by me for thee. Well-wishing Brahmanas duly worshipped and gratified the gods and the Pitris for your long life, wealth, and children, by adding Swaha and Swadha. The mother and the father, as also the gods always desire for their children liberality and gift and study and sacrifice and sway over subjects. Whether all this be righteous or unrighteous, you are to practise it, in consequence of your very birth. (Behold, O Krishna, so far from doing all this), though born in a high race, they are yet destitute of the very means of support, and are afflicted with misery. Hungry men, approaching a brave and bountiful monarch, are gratified, and live by his side. What virtue can be superior to this?
