Yājñavalkya taught Janaka about the great unborn Self that lies in the space within the heart, ruler of all, lord of all, which does not grow greater by a good deed or smaller by a bad one, the bridge that keeps the worlds from running into one another, which brahmins seek to know by study and sacrifice, by giving, by austerity and fasting, and for which wanderers leave their homes. Knowing it, he said, a man becomes calm and restrained, withdrawn and patient and collected; he sees the Self in himself and sees all as the Self. Evil does not overcome him; he overcomes all evil. Evil does not burn him; he burns all evil. That is the world of Brahman, your majesty, and I have brought you to it.
And Janaka said, Sir, I give you the people of Videha, and myself as well, to be your servant.
