Only if you have a clean heart can you learn ancient books. Otherwise, if you see a good deed, steal it for profit; I heard a good word, pretending to be short, and the soldiers stole food again.
Translation:
Only a person with a pure heart can read the Book of Quan Xian and learn the moral articles of the ancients. Otherwise, seeing good deeds will be used to satisfy your own selfish desires, and hearing famous words will be used to cover up your own shortcomings. This is tantamount to subsidizing weapons for thieves and food for robbers.
