知人者智，
自知者明。
勝人者有力，
自勝者強。
知足者富。
強行者有志。
不失其所者久。
死而不亡者，
壽。

Knowing others is wisdom;
Knowing the self is enlightenment.
Mastering others requires force;
Mastering the self needs strength.
He who knows he has enough is rich.
Perseverance is a sign of willpower.
He who stays where he is endures.
To die but not to perish is to be eternally present.
