In plain words
...of the man untouched by desire, whatever hundredfold bliss belongs to the gods born as gods, that is the single bliss of Prajāpati's world -- and the same is true of anyone learned in scripture, free of wrong, and untouched by desire. Now take the hundredfold bliss of Prajāpati's world itself: that becomes the single bliss of the world of brahman, again for anyone who is learned, blameless, and free of craving. And beyond that, there is nothing further to multiply -- this is simply the highest bliss there is. This is the world of brahman, your majesty." So Yājñavalkya finished. And Janaka said, "Then I give you, sir, a thousand cows for teaching me this much -- now tell me only of liberation, beyond it." And here Yājñavalkya grew afraid: the king was so sharp that he had cornered him at the end of every single answer, from every side.
Close to the Sanskrit
...of one unsmitten by desire: whatever hundred blisses belong to the gods-by-birth, that is the one bliss of Prajāpati's world; and whoever is learned in scripture, free of wrongdoing, and unsmitten by desire -- now, whatever hundred blisses belong to Prajāpati's world, that is the one bliss of the world of brahman; and whoever is learned in scripture, free of wrongdoing, and unsmitten by desire -- now, this alone is the supreme bliss; this is the world of brahman, O sovereign" -- thus did Yājñavalkya say. "So, being thus instructed, I give a thousand [cows] to the venerable one; beyond this, speak only of liberation" -- at this point Yājñavalkya became afraid. The intelligent king had checked him at every conclusion from every side.
