Mbh 15.6.1a

"'Dhritarashtra said, "Thou shouldst always ascertain the Mandalas that belong to thee, to thy foes, to neutrals, and to those that are disposed equally towards thee and thy foes, O Bharata.[12] The Mandalas also of the four kinds of foes, of these called Atatayins, and of allies, and the allies of foes, should be distinguished by thee, O crusher of foes.[13] The ministers of state, the people of the provinces, the garrisons of forts, and the forces, O foremost one of Kuru's race, may or may not be tampered with. (Thou shouldst, therefore, behave in such a manner that these may not be tampered with by thy foes). The twelve (enumerated above), O son of Kunti, constitute the principal concerns of kings. These twelve, as also sixty, having Ministers for their foremost, should be looked after by the king.[14] Professors conversant with the science of politics call these by the name of Mandala. Understand, O Yudhishthira, that the six incidents (of peace, war, march, halt, sowing dissensions, and conciliation) depend upon these. Growth and diminution should also be understood, as also the condition of being stationary. The attributes of the sixfold incidents, O thou of mighty arms, as resting on the two and seventy (already enumerated), should also be carefully understood. When one's own side has become strong and the side of the foe has become weak, it is then, O son of Kunti, that the king should war against the foe and strive to win victory. When the enemy is strong and one's own side is weak, then the weak king, if possessed of intelligence, should seek to make peace with the enemy. The king should collect a large store of articles (for his commissariat). When able to march out, he should on no account make a delay, O Bharata. Besides, he should on that occasion set his men to offices for which they are fit, without being moved by any other consideration.
