The wise man tells not what he knows. It is not prudent to sport with one's head by revealing the king's secrets.
SaadiAvoid that which an enemy tells you to do; for if you follow his advice, you will smite your, knees with the hand of sorrow. If he shows you a road straight as an arrow, turn from it and go the other way.
SaadiIf a piece of worthless stone can bruise a cup of gold, its worth is not increased, nor that of the gold diminished.
