The Great Epic of the Bhārata dynasty 5.33.91

5.33.91

na yo'bhyasūyatyanukampate ca na durbalaḥ prātibhāvyaṃ karoti |
nātyāha kiṃcitkṣamate vivādaṃ sarvatra tādṛglabhate praśaṃsām || 91 ||

Great prosperity attends upon that king who knoweth how to inspire confidence in others, who inflicteth punishment on those whose guilt hath been proved, who is acquainted with the proper measure of punishment, and who knoweth when mercy is to be shown. He is a wise person who doth not disregard even a weak foe; who proceeds with intelligence in respect of a foe, anxiously watching for an opportunity; who doth not desire hostilities with persons stronger than himself; and who displayeth his prowess in season. That illustrious person who doth not grieve when a calamity hath already come upon him, who exerteth with all his senses collected, and who patiently beareth misery in season, is certainly the foremost of persons, and all his foes are vanquished. He who doth not live away from hope uselessly, who doth not make friends with sinful persons, who never outrageth another's wife, who never betrayeth arrogance, and who never committeth a theft or showeth ingratitude or indulgeth in drinking is always happy. He who never boastfully striveth to attain the three objects of human pursuit, who when asked, telleth the truth, who quarreleth not even for the sake of friends, and who never becometh angry though slighted, is reckoned as wise. He who beareth not malice towards others but is kind to all, who being weak disputeth not with others, who speaketh not arrogantly, and forgeteth a quarrel, is praised everywhere.
