Between wisdom and enlightenment: self-understanding outshines knowledge of other people and things

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 power.
He who stays where he is endures.
To die but not to perish is to be eternally present.

Lao Tsu, Tao Te Ching, trans. G. Feng and J. English
