Mbh 5.9.2a

“Salya said, ‘Listen, O king, to me as I relate this ancient story of the events of former days,--how, O descendant of Bharata, misery befell Indra and his wife. Once Twashtri, the lord of creatures and the foremost of celestials, was engaged in practising rigid austerities. And it is said that from antipathy to Indra he created a son having three heads. And that being of universal form possessed of great lustre hankered after Indra’s seat. And possessed of those three awful faces resembling the sun, the moon, and the fire, he read the Vedas with one mouth, drank wine with another, and looked with the third as if he would absorb all the cardinal points. And given to the practice of austerities, and mild being and self-controlled, he was intent upon a life of religious practices and austerities. And his practice of austerities, O subduer of foes, was rigid and terrible and of an exceedingly severe character. And beholding the austerities, courage, and truthfulness of this one possessed of immeasurable energy, Indra became anxious, fearing lest that being should take his place. And Indra reflected, “How may he be made to addict himself to sensual enjoyments; how may he be made to cease his practice of such rigid austerities? For were the three-headed being to wax strong, he would absorb the whole universe.” And it was thus that Indra pondered in his mind; and, O best of Bharata’s race, endued with intelligence, he ordered the celestial nymphs to tempt the son of Twashtri. And he commanded them, saying, “Be quick, and go without delay, and so tempt him that the three-headed being may plunge himself into sensual enjoyment to the utmost extent. Furnished with captivating hips, array yourselves in voluptuous attires, and decking yourselves in charming necklaces, do ye display gestures and blandishments of love. Endued with loveliness, do ye tempt him and alleviate my dread. I feel restless in my heart, O lovely damsels.
