'But in reality he is an ativâdin who declares the Highest Being to be the True (Satya).' 'Sir, may I become an ativâdin by the True.' 'But we must desire to know the True.' 'Sir, I desire to know the True.'

In plain words: The teacher says the real ativadin is the one who speaks of the Highest as Truth itself. Narada says he wants that, and the teacher tells him he must first want to know the Truth. Narada says he does.
