dakṣa uvāca /
saṃcintaye bhagavataścaraṇodatīrthaṃ bhaktyā hyajena pariṣiktamajādivandyam /
yacchaucaniḥ sṛtamajapravarāvatāraṃ gaṅgākhyatīrthamabhavatsaritāṃ variṣṭham //

Dakṣa said: / With devotion I contemplate the holy ford of the Lord’s foot-water, sprinkled by the Unborn [Brahmā] and worshipped by the Unborn and others, / which, issuing for purification as the descent of the foremost among the unborn, became the sacred ford named Gaṅgā, the most excellent of rivers.
