There in Rasātala, the lower region of the universe, Purukutsa, being empowered by Lord Viṣṇu, was able to kill all the Gandharvas who deserved to be killed. Purukutsa received the benediction from the serpents that anyone who remembers this history of his being brought by Narmadā to the lower region of the universe will be assured of safety from the attack of snakes.
