Yajnavalkya called on Janaka, Emperor of Videha. He said to himself: I will not say anything. But once upon a time Janaka, Emperor of Videha and Yajnavalkya had had a talk about the Agnihotra sacrifice and Yajnavalkya had offered him a boon. Janaka had chosen the right to ask him any questions he wished and Yajnavalkya had granted him the boon. So it was the Emperor who first questioned him.

Yajnavalkya, what serves as light for a man? The light of the sun, O Emperor, said Yajnavalkya, for with the sun as light he sits, goes out, works and returns. Just so, Yajnavalkya.
