Why do no gauds those limbs adorn Where priceless gems were meetly worn? Each noble youth is fit, I deem, To guard this earth, as lord supreme, With all her woods and seas, to reign From Meru’s peak to Vindhya’s chain.

In plain words: Hanuman asks why they wear no jewels, though they look born to wear them. He says each of them seems fit to rule the whole earth, from Mount Meru to the Vindhya mountains.
