Avoid 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.
SaadiThe sea does not contain all the pearls, the earth does not enclose all the treasures, and the flint-stone does not inclose all the diamonds, since the head of man encloses wisdom.
SaadiNo reliance can be placed on the friendship of kings, nor vain hope put in the melodious voice of boys; for that passes away like a vision, and this vanishes like a dream.
