Mbh 5.123.2

“Narada continued, ‘O monarch, even such was the distress into which Yayati fell in consequence of vanity, and such was the distress into which Galava fell owing to his obstinacy. They that desire their own good should listen to friends that wish them well. Obstinacy should never be entertained, for obstinacy is always the root of ruin. For this reason, O son of Gandhari, forsake vanity and wrath. O hero, make peace with the sons of Pandu. Avoid anger, O king, that which is given away, that which is done, the austerities that are practised, the libations that are poured on fire, not one of these is ever destroyed or suffereth any diminution. None else, again, enjoyeth the fruits of these save he that is their agent. He that succeedeth in understanding this truly superior and excellent history, that is approved by persons of great learning as well as by those that are freed from anger and lust, and that is enforced by various references to scriptures and reason, obtaineth a knowledge of virtue and profit and desire, and enjoyeth the sovereignty of the whole world!’”
