Mbh 12.140.3a

"'"The Rishi said, 'The king should always stay with the rod of chastisement uplifted in his hand. He should always display his prowess. Himself without laches, he should mark the laches of his foes. Indeed, his eyes should ever be used for that purpose. At the sight of a king who has the rod of chastisement ever uplifted in his hand, every one is struck with fear. For this reason, the king should rule all creatures with the rod of chastisement. Men possessed of learning and knowledge of truth applaud Chastisement. Hence, of the four requisites of rule, viz., Conciliation, Gift, Disunion, and Chastisement, Chastisement is said to be the foremost. When the foundation of that which serves for a refuge is cut away, all the refugees perish. When the roots of a tree are cut away, how would the branches live? A king possessed of wisdom should cut away the very roots of his foe. He should then win over and bring under his sway the allies and partisans of that foe. When calamities overtake the king, he should without losing time, counsel wisely, display his prowess properly, fight with ability, and even retreat with wisdom. In speech only should the king exhibit his humility, but at heart he should be sharp as a razor. He should cast off lust and wrath, and speak sweetly and mildly. When the occasion comes for intercourse with an enemy, a king possessed of foresight should make peace, without reposing blind trust on him. When the business is over, he should quickly turn away from the new ally. One should conciliate a foe with sweet assurances as if he were a friend. One, however, should always stand in fear of that foe as living in a room within which there is a snake. He whose understanding is to be dominated by thee (with the aid of thine intellect) should be comforted by assurances given in the past. He who is of wicked understanding should be assured by promises of future good. The person, however, that is possessed of wisdom, should be assured by present services.
