रविलोचनः, 'अग्निर्मूर्धा चक्षुषी चन्द्रसूर्यौ' इति श्रुतेः ॥
In plain words
Ravilocana: the one whose eye is the sun. This on the authority of śruti — "Fire is his head; his two eyes are the moon and the sun."
Close to the Sanskrit
Ravilocanaḥ — 'he whose eye is the sun' — because of the śruti: 'Fire is his head, his two eyes are the moon and the sun.'
