Tao Te Ching

“Can you hold a red-hot iron rod in your hand merely because some one wants you to do so? Then, will it be right on your part to ask others to do the same thing just to satisfy your desires? If you cannot tolerate infliction of pain on your body or mind by others' words and actions, what right have you to do the same to others through your words and deeds?”

— Mahavira 540 – 468 BCE
