To know people is wisdom, but to know yourself is enlightenment. to master people takes force, but to master yourself takes strength. to know contentment is wealth, and to live with strength resolve. to never leave whatever you are is to abide, and to die without getting lost- that is to live on and on.
Under heaven all can see beauty as beauty only because there is ugliness. All can know good as good only because there is evil. Therefore having and not having arise together. Difficult and easy complement each other. Long and short contrast each other. High and low rest upon each other. Voice and sound harmonize each other. Front and back follow one another.
The very highest is barely known.
Then comes that which people know and love,
Then that which is feared,
Then that which is despised.
Who does not trust enough will not be trusted.
The universe is deathless; Is deathless because, having no finite self, it stays infinite. A sound man by not advancing himself stays the further ahead of himself, By not confining himself to himself sustains himself outside himself: By never being an end in himself he endlessly becomes himself.
