kiṃ tasya tapasā rājñaḥ kiṃ ca tasyādhvarairapi |
apālitāḥ prajā yasya sarvā dharmavinākṛtāḥ || 71 ||

They are his own self, his counsellors, his treasury, his machinery for awarding punishments, his friends, his provinces, and his capital. He should with care protect his kingdom which consists of these seven limbs. That king, O tiger among men, who is conversant with the aggregate of six, the triple aggregate, and the high aggregate of three, succeeds in winning the sovereignty of the whole earth. Listen, O Yudhishthira, to what has been called the aggregate of six. These are ruling in peace after concluding a treaty (with the foe), marching to battle, producing disunion among the foe, concentration of forces, for inspiring the foe with fear, preparedness for war with readiness for peace, and alliance with others. Listen now with attention to what has been called the triple aggregate. They are decrease, maintenance of what is, and growth. The high aggregate of three consists of Virtue, Profit and Pleasure. These should be pursued judiciously. By the aid of virtue, a king succeeds in ruling the earth for ever. Touching this matter, Angirasa's son: Vrihaspati himself has sung two verses. Blessed be thou, O son of Devaki, it behoveth thee to hear them. 'Having discharged all his duties and having protected the earth, and having also protected his cities, a king attains to great happiness in heaven. What are penances to that king, and what need has he of sacrifices who protects his people properly? Such a king should be regarded as one conversant with every virtue!'
