Mbh 3.122.1a

“Lomasa said, ‘A son was born to the great saint Bhrigu, Chyavana by name. And he, of an exceedingly resplendent form, began to practise austerities by the side of yonder lake. And, O Pandu’s son! O protector of men! he of mighty energy assumed the posture called Vira, quiet and still like an inanimate post, and for a long period, remained at the same spot of ground. And he was turned into an anthill covered over with creepers. And after the lapse of a long period, swarms of ants enveloped him. And covered all over with ants, the sagacious saint looked exactly like a heap of earth. And he went on practising austerities, enveloped on all sides with that ant-hill. Now after the lapse of a long space of time, that ruler of earth, Saryati by name, for amusement visited this pleasant and excellent lake. With him were four thousand females, espoused by him, O son of Bharata’s race! there was also his only daughter endued with beautiful brows, named Sukanya. She surrounded by her maids, and decked out with jewels fit for the celestials, while walking about, approached the anthill where Bhrigu’s son was seated. And surrounded by her maids, she began to amuse herself there, viewing the beautiful scenery, and looking at the lofty trees of the wood. And she was handsome and in the prime of her youth; and she was amorous and bent on frolicking. And she began to break the twigs of the forest trees bearing blossoms. And Bhrigu’s son endued with intelligence beheld her wandering like lightning, without her maids, and wearing a single piece of cloth and decked with ornaments. And seeing her in the lone forest, that ascetic of exceeding effulgence was inspired with desire. And that regenerate Rishi possessing ascetic energy, who had a low voice, called the auspicious one,--but she heard him not. Then seeing the eyes of Bhrigu’s son from the ant-hill, Sukanya from curiosity and losing her sense, said, ‘What is this?’--and with thorns pierced the eyes (of the Rishi).
