iti bruvams citra-rathah sva-sarathim
yattah paresam pratiyoga-sankitah
susrava sabdam jaladher iveritam
nabhasvato diksu rajo ’nvadrsyata
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
In the meantime, while Dhruva Maharaja, doubtful of his mystic enemies, was talking with his charioteer, they heard a tremendous sound, as if the whole ocean were there, and they found that from the sky a great dust storm was coming over them from all directions.
