Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Mandhata, the King of the entire world, consisting of seven islands, was struck with wonder when he saw the household opulence of Saubhari Muni. Thus he gave up his false prestige in his position as emperor of the world.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Everyone is proud of his own position, but here was an astounding experience, in which the emperor of the entire world felt himself defeated in all details of material happiness by the opulence of Saubhari Muni.
