Once, the Ashvins visited the hermitage of Chyavana. They saw the beautiful Sukanya while she was bathing. They tried to convince Sukanya to reject the old and ugly Chyavana, and accept one of them as her husband. Furious, the princess rejected their proposal. The deities then promised to restore the youth and eyesight of Chyavana first, so that she could make an unbiased choice amongst her present husband, and one of them. The princess was tempted, because this would mean that her husband's vigour would be restored. Sukanya promised to consider their proposal, and informed Chyavana. At the behest of Chyavana, Sukanya requested the Ashvins to allow her to make her choice. All three took a bath in the lake, and came out with the same youthful, divine look. Each of them requested Sukanya to be his bride, but she successfully identified Chyavana and selected him, in some accounts, after praying to Adi Parashakti. Sukanya managed to identify Chyavana by observing the eyes of all the three of them; Gods don't blink and thus she picked the person who blinked. In gratitude for his restored youth and eyesight, Chyavana assured the Ashvins that he would ensure that the deities would get their share of the sacrificial offerings.
