Original text:
He who knows others is wise, and he who knows himself is wise. He who conquers others is strong, and he who conquers himself is strong. Those who are satisfied are rich, and those who are forced are ambitious. He who does not lose his position for a long time dies but does not die.
Translation:
He who can understand others is smart, and he who can understand himself is smart. He who can defeat others is strong, and he who can defeat himself is stronger and invincible. People who know how to be content are rich, and those who persist in doing it are ambitious. Only those who do not lose their duty can live long, and those who still have Tao after death can live long.
Extended data:
People who can know others are smart, and people who can know themselves are wise. Later, it was used to show that people should be good at paying attention to personal cultivation and introspection.
He also believes that personal spiritual cultivation can make people have intelligence, intelligence, strength, strength, wealth, ambition, longevity, longevity and other qualities, which are all positive. Laozi strongly advocates "immortality", which is his consistent ideological proposition and embodies the ideological theme of "inaction"
"To die without dying" is not to promote the theory of ghosts and gods, nor to promote the immortality of the soul, but to say that although the human body has disappeared, the human spirit is immortal and eternal, which can of course be regarded as longevity.
