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.
Knowing things makes you smart,
but knowing yourself makes you wise.
To rule others, you must be powerful,
but to rule yourself,
you must be strong.
If you have only what you need,
you have true wealth.
If you never give up,
you will find a way.
If you stay true to yourself,
you will never be lost.
If you stay alive your whole life,
you've really lived.
