Regret will not leave the hearts of two persons and their feet of contention will not emerge from the mire: a merchant with a wrecked ship and a youth sitting with qalandars.
Dervishes will consider it licit to shed thy blood
If they can have no access to thy property.
Either associate not with a friend who dons the blue garb,
Or bid farewell to all thy property.
Either make no friends with elephant-keepers
Or build a house suitable for elephants.
Saadi Shirazi
