तया रसातलं नीतो भुजगेन्द्रप्रयुक्तया ॥ २ ॥
tayā rasātalaṁ nīto
narmadā — by the name Narmadā; bhrātṛbhiḥ — by her brothers; dattā — was given in charity; purukutsāya — unto Purukutsa; yā — she who; uragaiḥ — by the serpents (sarpa-gaṇa); tayā — by her; rasātalam — to the lower region of the universe; nītaḥ — was brought; bhujaga-indra-prayuktayā — engaged by Vāsuki, the King of the serpents.
The serpent brothers of Narmadā gave Narmadā to Purukutsa. Being sent by Vāsuki, she took Purukutsa to the lower region of the universe.
Before describing the descendants of Purukutsa, the son of Māndhātā, Śukadeva Gosvāmī first describes how Purukutsa was married to Narmadā, who was induced to take him to the lower region of the universe.
