Mbh 12.93.1c

A king who is devoted to virtue, having acquired the sovereignty of the earth by prowess, should protect his subjects righteously and slaughter foes in battle. Everything belonging to this world is destined to destruction. Nothing here is durable. For this reason, the king, adhering to righteousness, should protect his subjects righteously. The defence of forts, battle, administration of justice, consultations on questions of policy, and keeping the subjects in happiness, these five acts contribute to enlarge the dominions of a king. That king who takes proper care of these is regarded to be the best of kings. By always attending to these, a king succeeds in protecting his kingdom. It is impossible, however, for one man to supervise all these matters at all times. Making over such supervision to his ministers, a king may govern the earth for ever.[277] The people make such a person their king who is liberal, who shares all objects of enjoyment with others, who is possessed of a mild disposition, who is of pure behaviour, and who will never abandon his subjects. He is obeyed in the world who, having listened to counsels of wisdom, accepts them, abandoning his own opinions. That king who does not tolerate the counsels of a well-wisher in consequence of their opposition to his own views, who listens with inattention to what is said unto him in opposition to his views, and who does not always follow the conduct of high and noble persons conquered or unconquered, is said to fall away from the duties of Kshatriyas. From ministers that have once been chastised, from women in especial, from mountains and inaccessible regions, from elephants and horses and reptiles, the king should always, with heedfulness, protect his own self.[278] That king who, abandoning his chief ministers, makes favourites of low persons, soon falls into distress, and never succeeds in compassing the (intended) ends of his measures.
