Mbh 3.25.1b

Yet that sinless one had to dwell in the forest at the command of his father, accepting it as his duty. The illustrious Rama was equal unto Sakra in prowess, and invincible in battle. And yet he had to range the forest renouncing all pleasures! Therefore should no one act unrighteously, saying,--I am mighty! Kings Nabhaga and Bhagiratha and others, having subjugated by truth this world bounded by the seas, (finally) obtained, O child, all the region hereafter. Therefore, should no one act unrighteously, saying,--I am mighty! And, O exalted of men, the virtuous and truthful king of Kasi and Karusha was called a mad dog for having renounced his territories and riches! Therefore, should no one act unrighteously, saying,--I am mighty! O best of men, O son of Pritha, the seven righteous Rishis, for having observed the ordinance prescribed by the Creator himself in the Vedas, blaze in the firmament. Therefore, should no one act unrighteously, saying,--I am mighty! Behold, O king, the mighty elephants, huge as mountain cliffs and furnished with tusks, transgress not, O exalted of men, the laws of the Creator! Therefore, should none act unrighteously saying, Might is mine! And, O foremost of monarchs, behold all the creatures acting according to their species, as ordained by the Creator. Therefore, should none act unrighteously, saying, Might is mine. O son of Pritha, in truth, and virtue, and proper behaviour, and modesty, thou hast surpassed all creatures, and thy fame and energy are as bright as fire or the Sun! Firm in thy promises, O illustrious one, having passed in the woods thy painful exile, thou wilt again, O king, snatch from the Kauravas thy blazing prosperity with the help of thy own energy!’”
