O Pushan, only seer, Yama (judge), Surya (sun), son of Pragapati, spread thy rays and gather them! The light which is thy fairest form, I see it. I am what he is (viz. the person in the sun).

In plain words: The prayer calls the sun by many names, including Pushan, the lone seer, Yama the judge, and Surya, son of Prajapati. It asks the sun to spread out its rays and gather them in. The worshipper says he sees its most beautiful light, and declares, 'I am that same being who lives in the sun.'
