5.6.13

tatkulīnam aparuddhaṃ vā bhūṃyekadeśenopagrāhayet //

Whoever, among the neighbouring kings, seems to threaten with an invasion may be invited for some festival, marriage, capture of elephants, purchase of horses, or of merchandise, or for taking possession of some lands ceded to him, and captured; or such an enemy may be kept at bay by an ally till an agreement of not condemnable nature is made with him; or he may be made to incur the displeasure of wild tribes or of his enemies; or whoever among his nearest relatives is kept under guard may be promised a portion of his territory and set against him.
