However 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?
SaadiIf a gem falls into mud it is still valuable. If dust ascends to heaven, it remains valueless.
SaadiThe sons of Adam are limbs of each other, Having been created of one essence. When the calamity of time affects one limb, the other limbs cannot remain at rest. If you have no sympathy for the troubles of others, You are unworthy to be called by the name of a human.
Saadi
