What is an example of practical advice for peace and inner-strength in the Analects?
An example of practical advice for peace and inner-strength by Confucious in the Analects is making decisions led by virtue and not law.
At one point, the master explains that people should not do what they do just to follow laws and avoid punishment.
"If they be led by virtue, and uniformity sought to be given them by the rules of propriety, they will have the sense of shame, and moreover will become good." (http://classics.mit.edu/Confucius/analects.mb.txt)
If a person focuses only on what the law says, the person is only acting to avoid punishment. This is not real virtue. Following the law does not develop a sense of shame. It is a sense of shame that develops virtuous behavior when it is coupled with ritual respect for proper relationships.
