nibadhya navam tac-chrnge
yathokto harina pura
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Following the instructions formerly given by the Supreme Personality of Godhead, the King anchored the boat to the fish’s horn, using the serpent Vasuki as a rope. Thus being satisfied, he began offering prayers to the Lord.
