Those who know others are intelligent Those who know themselves have insight. Those who master others have force Those who master themselves have strength.Those who know what is enough are wealthy. Those who persevere have direction. Those who maintain their position endure. And those who die and yet do not perish, live on.
LaoziThe living are soft and yielding; the dead are rigid and stiff. Living plants are flexible and tender; the dead are brittle and dry.
Laozi
