The Mahabharata/Book 1: Adi Parva…
“ Yayati then said, 'I solicit the boon, O Brahmana, that by so doing, the sin of begetting a half-breed might not touch me.' Sukra, however, assured him by saying, 'I shall absolve thee from the sin. Ask thou the boon that thou desirest. Fear not to wed her. I grant thee absolution. Maintain virtuously thy wife--the slender-waisted Devayani. Transports of happiness be thine in her company. ”
