7.2.27

yadrājā munaye'ndhāya dattā putrī sulocanā |
kurūpā guṇahīnā vā nārī lakṣaṇavarjitā ||

Janamejaya said:-- “O Brahmâns! How is it that the King S'aryâti married his lovely-eyed daughter Sukanyâ to the blind Chyavana Muni? I have got a great doubt on this point. The King gives his daughter in marriage to a blind person, if she be deformed, ill-qualified or void of female signs. But the daughter, in this case, was beautiful. How then S'aryâti, the Chief of Kings, gave over his daughter, knowing that the Risi was blind? O Brâhmana! I am always an object of favour to you; so explain to me the cause of it.”
