Verse Thirty Three – 33

Those who know others are intelligent;
those who know themselves are truly wise.

Those who master others are strong;
those who master themselves have true power.

Those who know they have enough are truly wealthy.
Those who persist will reach their goal.

Those who keep their course have a strong will.
Those who embrace death will not perish,
but have life everlasting.
