7.14.4

vairaṃ vā parair grāhayitvā visaṃvādayet //

The combination being broken, he may set the leader against the weak among his enemies; or offering inducements, he may set the combined power of the weak against the leader; or in whatever way be may find it to be conducive to his own prosperity, in that way he may make the leader incur the displeasure of others, and thus frustrate their attempts; or showing the prospect of a larger profit, he may through intrigue, make peace with their leader. Then the recipients of salaries from two states, exhibiting the acquisition of large profits (to the leader), may satirise the kings, saying, "You are all very well combined."
