ITRANS:

pitary uparate so ’picakravartī mahā-yaśāḥmahimā gīyate tasyaharer aṁśa-bhuvo bhuvi

Translation:

Śukadeva Gosvāmī said: When Mahārāja Duṣmanta passed away from this earth, his son became the emperor of the world, the proprietor of the seven islands. He is referred to as a partial representation of the Supreme Personality of Godhead in this world.

Purport:

In Bhagavad-gītā (10.41) it is said: Anyone extraordinarily powerful must be considered a partial representation of the opulence of the Supreme Godhead. Therefore when the son of Mahārāja Duṣmanta became the emperor of the entire world, he was celebrated in this way.
