Ne’er could I find so rich a coat On spotted deer or sheep or goat. No buck or antelope has such, So bright to view, so soft to touch. This radiant deer and one on high That moves in glory through the sky, Alike in heavenly beauty are, One on the earth and one a star.

In plain words: Rama says he has never seen such a rich, soft coat on any deer, sheep, or goat. He compares the deer to a heavenly star on earth.
