In plain words
'Please, Yajnavalkya, tell us this: the eye alone is the home, space is its foundation -- call it Truth, and meditate on it that way.' 'And what makes it true?' 'The eye itself, Your Majesty. Because it's by the eye that a man sees -- people ask him, 'Did you see it?' and he says, 'I saw it' -- and that's exactly what makes it true. The eye, Your Majesty, is the supreme Brahman. It never abandons the one who knows this; every being streams toward him; he becomes a god and joins the gods -- anyone who understands this and lives by it.' Janaka of Videha said, 'I'll give you a thousand cattle and a prize bull for that.' Yajnavalkya answered, 'My father always held: never accept a gift before you've taught the whole thing.'

[Janaka said:] 'Please tell us, Yājñavalkya -- the eye alone is the abode, space is the support; call it truth; one should meditate upon it thus.' [Yājñavalkya asked:] 'What is its truth-quality, Yājñavalkya... O emperor?' [He] said: 'The eye alone, O emperor.' 'By the eye, indeed, O emperor, when a man is seeing, they say to him, 'Did you see?' He says, 'I saw' -- that becomes the truth. The eye, indeed, O emperor, is the supreme Brahman. The eye never leaves him; all beings flow toward him; having become a god, he attains the gods -- whoever, knowing thus, worships this.' Janaka of Videha said: 'I give a thousand cattle with a bull-elephant.' Yājñavalkya said: 'My father held that one should not accept a gift without having fully taught.'
