Sakalya said: 'Whosoever knows that person whose dwelling are the colours, whose sight is the eye, whose mind is light,—the principle of every self, he indeed is a teacher, O Yagnavalkya.' Yagnavalkya replied: 'I know that person, the principle of every self, of whom thou speakest. That person in the sun, "he is he." But tell me, Sakalya, who is his devata?' Sakalya replied: 'The True.'

In plain words: Sakalya asks about the being whose home is colours and whose seeing is the eye. Yagnavalkya says it is the person in the sun. Sakalya says its deity is the True.
