The Mahabharata — Section CLXVIII
“ The Brahmana said, 'At that region where the Ganga entered the plains there lived a great Rishi, devoted to the austerest of penances. Of rigid vows and great wisdom, he bore the name Bharadwaja. One day, on coming to the Ganga to perform his ablutions, the Rishi saw the Apsara Ghritachi, who had come before, standing on the bank after her ablutions were over. ”
