Mbh 12.69.4c

By causing the Kali age, the king incurs a heavy load of sin. Stained by wickedness, he rots in hell for innumerable years, for sinking in the sins of his subjects, he incurs great sin and infamy himself. Keeping the great science in his view, the Kshatriya possessed of learning should strive to acquire those objects which he desires and protect those that have been already acquired. The science of chastisement, which establishes all men in the observance of their respective duties, which is the groundwork of all wholesome distinctions, and which truly upholds the world and sets it agoing, if properly administered, protects all men like the mother and the father protecting their children. Know, O bull among men, that the very lives of creatures depend upon it. The highest merit a king can acquire is acquaintance with the science of chastisement and administering it properly. Therefore, O thou of Kuru's race, protect thy subjects righteously, with the aid of that great science. By protecting the subjects and adopting such a conduct, thou wilt surely attain to such blessedness in heaven as is difficult of acquisition."'"
