sa varsa-pugan udadhau maha-balas

maurvyabhijaghne gadaya vibhavarim
asedivams tata purim pracetasah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Moving about in the ocean for many, many years, the mighty Hiranyaksa smote the gigantic wind-tossed waves again and again with his iron mace and reached Vibhavari, the capital of Varuna.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Varuna is supposed to be the predominating deity of the waters, and his capital, which is known as Vibhavari, is within the watery kingdom.
