Mbh 12.30.2b

The virtuous Narada, however, overwhelmed by shame, could not disclose that burning attachment to his sister's son, the high-souled Parvata. By his ascetic power, as also by signs, Parvata understood all. Inflamed with rage, the latter thereupon resolved to curse the love-afflicted Narada. And he said, 'Having of thy own accord made a compact with me that, whatever wish, good or bad, would be cherished by either of us should be disclosed to the other, thou hast violated it. These were thy own words, O Brahmana! It is for this that I shall curse thee. Thou didst not tell me before that thy heart has been pierced by the charms of the maiden Sukumari! It is for this that I shall curse thee. Thou art a Brahmacharin. Thou art my preceptor. Thou art an ascetic and a Brahmana. Yet hast thou broken the compact thou hadst made with me. Fitted with rage I shall, for this, curse even thee. Listen to me. This Sukumari shall, without doubt, become thy wife. From the time of thy marriage, however, O puissant one, both she and all men shall behold thee an ape, for thy true features having disappeared, an ape shalt thou appear unto all.' Hearing these words of his, the uncle Narada, filled with wrath, cursed his nephew Parvata in return, saying, 'Although thou hast ascetic merit and Brahmacharya and truth and self-restraint, and although thou art ever devoted to virtue, thou shalt not yet succeed in proceeding to heaven.' Filled with rage and desire of vengeance, they thus cursed and flamed against each other like a couple of infuriated elephants. From that time the high-souled Parvata began to wander over the earth, respected as he deserved, O Bharata, for his own energy. Narada then, that foremost of Brahmanas, obtained according to due rites the hand of Srinjaya's daughter, the faultless Sukumari. The princess, however, beheld Narada exactly as the curse had said.
