Know that acts of courtesy earn praiseworthy results, and end in rewardable gains. If you were to see acts of courtesy personified as a man, you would perceive him to be good and handsome, pleasing for people to behold and transcending all the worlds. And if you were to see acts of vileness personified, you would perceive an ugly, revolting, disfigured man, whom the hearts would be averse to and whom the eyes would turn away from in disgust.
