Mbh 3.122.1b

And as his eyes being pierced by her, he felt exceeding pain and became wroth. And (from anger) he obstructed the calls of nature of Saryati’s forces. And on their calls of nature being obstructed, the men were greatly afflicted. And seeing this state of things, the king asked. ‘Who is it that hath done wrong to the illustrious son of Bhrigu, old and ever engaged in austerities and of wrathful temper? Tell me quick if ye know it’. The soldiers (thereupon) answered him saying, ‘We do not know whether any one hath done wrong to the Rishi. Do thou, as thou list, make a searching enquiry into the matter. Thereupon that ruler of earth, using (as he saw occasion) both menace and conciliation, asked his friends (about the circumstance). But they too did not know anything. Seeing that the army was distressed owing to the obstruction of the calls of nature, and also finding her father aggrieved, Sukanya said, ‘Roving in the forest, I lighted in the ant-hill here upon some brilliant substance. Thereupon taking it for a glow-worm I neared it, and pierced it (with thorns); Hearing this Saryati immediately came to the ant-hill, and there saw Bhrigu’s son, old both in years and austerities. Then the lord of earth with joined hands, besought (the ascetic) saying, ‘It behoveth thee to forgive what my daughter through ignorance and greenness, hath done unto thee.” Chyavana the son of Bhrigu, addressed the monarch saying, ‘Disregarding me, this one, filled with pride hath pierced my eyes. Even her, O king, endued with beauty and who was bereft of her senses by ignorance and temptation--even thy daughter would I have for my bride, I tell thee truly, on this condition alone will I forgive thee.’
