Here you will find the Poem Ch 01 Manner of Kings Story 38 of poet Sa di
A company of philosophers were discussing a subject in the palace of Kesra and Barzachumihr, having remained silent, they asked him why he took no share in the debate. He replied: "Veziers are like physicians and the latter give medicine to the sick only but, as I perceive that your opinions are in conformity with propriety, I have nothing to say about them." When an affair succeeds without my idle talk It is not meet for me to speak thereon. But if I see a blind man near a well It is a crime for me to remain silent.
