The advantage of abstinence, or rather, great moderation in eating and drinking, is thus curiously illustrated: Two dervishes travelled together; one was a robust man, who regularly ate three meals every day, the other was infirm of body, and accustomed to fast frequently for two days in succession. On their reaching the gate of a certain town, they were arrested on suspicion of being spies, and both lodged, without food, in the same prison, the door of which was then securely locked. Several days after, the unlucky dervishes were found to be quite innocent of the crime imputed to them, and on opening the door of the prison the strong man was discovered to be dead, and the infirm man still alive. At this circumstance the officers of justice marvelled; but a philosopher observed, that had the contrary happened it would have been more wonderful, since the one who died had been a great eater, and consequently was unable to endure the want of food, while the other, being accustomed to abstinence, had survived. Of Nushirvan the Just (whom the Greeks called Chosroe), of the Sassanian dynasty of Persian kings--sixth century--Saadi relates that on one occasion, while at his hunting-seat, he was having some game dressed, and ordered a servant to procure some salt from a neighbouring village, at the same time charging him strictly to pay the full price for it, otherwise the exaction might become a custom. His courtiers were surprised at this order, and asked the king what possible harm could ensue from such a trifle. The good king replied: "Oppression was brought into the world from small beginnings, which every new comer increased, until it has reached the present degree of enormity." Upon this Saadi remarks: "If the monarch were to eat a single apple from the garden of a peasant, the servant would pull up the tree by the roots; and if the king order five eggs to be taken by force, his soldiers will spit a thousand fowls. The iniquitous tyrant remaineth not, but the curses of mankind rest on him for ever."
