srotasāṁ pravarā saumya
tasyāḥ—of Devahūti; tat—that; yoga—by yoga practice; vidhuta—relinquished; mārtyam—material elements; martyam—her mortal body; abhūt—became; sarit—a river; srotasām—of all rivers; pravarā—the foremost; saumya—O gentle Vidura; siddhi-dā—conferring perfection; siddha—by persons desiring perfection; sevitā—resorted to.
Dear Vidura, the material elements of her body have melted into water and are now a flowing river, which is the most sacred of all rivers. Anyone who bathes in that river also attains perfection, and therefore all persons who desire perfection go bathe there.
