Mbh 13.55.3a

"'"Chyavana said, 'Listen to me as I tell thee in detail the reasons which had impelled me in all these acts of mine. Asked by thee, O monarch, I cannot refuse to enlighten thee. In days past, on one occasion, when the deities had assembled together, the Grandsire Brahman said some words. I heard them, O king, and shall presently repeat them to thee. "In consequence of a contention between Brahmana and Kshatriya energy, there will occur an intermixture in my race.[312] Thy grandson, O king, will become endued with great energy and puissance." Hearing this, I came hither, resolved to exterminate thy race. Indeed, I came, O Kusika, seeking the utter extermination of thy race,--in fact, for consuming into ashes all thy descendants. Impelled by this motive I came to thy palace, O monarch, and said unto thee, "I shall observe some vow. Do thou attend upon me and serve me dutifully." While residing, however, in thy house I failed to find any laches in thee. It is for that reason, O royal sage, that thou art still alive, for otherwise thou wouldst have by this time been numbered with the dead. It was with this resolution that I slept for one and twenty days in the hope that somebody would awake me before I arose of my own accord. Thou, however, with thy wife, didst not awaken me. Even then, O best of kings, I became pleased with thee. Rising from my bed I went out of the chamber without accosting any of you. I did this, O monarch, in the hope that thou wouldst ask me and thus I would have an opportunity of cursing thee. I then made myself invisible, and again showed myself in the room of thy palace, and, once more betaking myself to Yoga, slept for one and twenty days. The motive that impelled me was this. Worn out with toil and hunger you two would be angry with me and do what would be unpleasant to me. It was from this intention that I caused thyself and thy spouse to be afflicted with hunger.
