Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When King Bhagiratha approached Lord Siva and requested him to sustain the forceful waves of the Ganges, Lord Siva accepted the proposal by saying, “Let it be so.” Then, with great attention, he sustained the Ganges on his head, for the water of the Ganges is purifying, having emanated from the toes of Lord Visnu.
