All human beings are limbs of the same body. God created them from the same essence. If one part of the body suffers pain, then the whole body is affected. If you are indifferent to this pain, you cannot be called a human being.
SaadiHowever much you study, you cannot know without action. A donkey laden with books is neither an intellectual nor a wise man. Empty of essence, what learning has he whether upon him is firewood or book?
SaadiUse a sweet tongue, courtesy, and gentleness, and thou mayest manage to guide an elephant by a hair.
