Mbh 12.105.3a

"'"The sage said, 'Renouncing pride and desire and ire and joy and fear, wait upon thy very foes, humbling thyself and joining thy hands. Do thou serve Janaka the ruler of Mithila, always performing good and pure deeds. Firmly devoted to truth, the king of Videha will certainly give thee great wealth. Thou shalt then become the right arm of that king and obtain the trust of all persons. As a consequence of this, thou shalt then succeed in obtaining many allies possessed of courage and perseverance, pure in behaviour, and free from the seven principal faults. A person of restrained soul and having his senses under control, by adhering to his duties, succeeds in raising himself and gladdening others. Honoured by Janaka possessed of intelligence and prosperity, thou shalt certainly become the right arm of that ruler and enjoy the confidence of all. Having then mustered a large force and held consultations with good ministers, do thou cause disunion among thy foes and, setting them against one another, break them all like a person breaking a vilwa with a vilwa. Or, making peace with the foes of thy foe, destroy the latter's power.[323] Thou shalt then cause thy foe to be attached to such good things as are not easily attainable, to beautiful women and cloths, beds and seats and vehicles, all of very costly kinds, and houses, and birds and animals of diverse species, and juices and perfumes and fruits, so that thy foe may be ruined of himself.[324] If one's foe be thus managed, or if indifference is to be shown towards him, one that is desirous of acting according to good policy, should never suffer that foe to know it at all. Following the behaviour that is approved by the wise, do thou enjoy every kind of pleasure in the dominions of thy foe, and imitating the conduct of the dog, the deer, and the crow, behave, with apparent friendship, towards thy enemies. Cause them to undertake achievements that are mighty and difficult to accomplish.
