7.8.2

paṇamānaḥ kṣayavyayapravāsapratyavāyaparopakāraśarīrābādhāṃś cāsya varṇayet //

WHEN an assailable enemy who is in danger of being attacked is desirous of taking upon himself the condition which led one king to combine with another against himself, or of splitting them from each other, he may propose peace to one of the kings on the condition of himself paying twice the amount of profit accruing from the combination. The agreement having been made, he may describe to that king the loss of men and money, the hardships of sojourning abroad, the commission of sinful deeds, and the misery and other personal troubles to which that king would have been subjected. When the king is convinced of the truth, the amount promised may be paid; or having made that king to incur enmity with other kings, the agreement itself may be broken off.
