Mbh 5.129.4b

Prosperity worshippeth greatly that person who hath conquered his senses and his counsellors, who inflicteth punishments on transgressors, who acteth after deliberation, and who is possessed of wisdom. Lust and wrath that dwell in the body are deprived of their strength by wisdom, like a couple of fishes ensnared in a net with close holes. Those two in consequence of which the gods shut the gates of heaven against one, who freed from worldly propensities is desirous of going thither, are excited by lust and wrath. That king who knoweth well how to conquer lust and wrath and avarice and boastfulness and pride, can own the sovereignty of the whole earth. That king who is desirous of gaining wealth and virtue and vanquishing his enemies, should always be engaged in controlling his passions. Influenced by lust, or from wrath, he that behaveth deceitfully towards his own kinsmen or others, can never win many allies. Uniting thyself with those chastisers of foes--the heroic sons of Pandu--who are all endued with great wisdom, thou canst, O son, enjoy the earth in happiness. What Bhishma, the son of Santanu, and that mighty car-warrior, Drona, have told thee is, O son, quite true,--Krishna and Dhananjaya are invincible. Seek thou, therefore, the protection of this mighty-armed one, this one that is not worried by exertion, for if Kesava becometh gracious, both sides will be happy. That man, who is not obedient to the wishes of wise and learned friends, always seeking his prosperity, only gladdeneth his enemies. O son, there is no good in battle, no virtue, no profit. How can it bring happiness then? Even victory is not always certain. Do not set thy heart, therefore, on battle. O thou of great wisdom, Bhishma and thy father and Vahlika (formerly) gave unto the Pandavas their share (of the kingdom) from fear. O chastiser of foes, never think of disunion with them.
