The Master said, If out of the three hundred songs I had to take one phrase to cover all my teachings, I would say 'Let there be no evil in your thoughts.'
ConfuciusThe superior man does what is proper to the station in which he is; he does not desire to go beyond this. In a position of wealth and honor, he does what is proper to a position of wealth and honor. In a poor and low position, he does what is proper to a poor and low position.
Confucius
