gravity is the source of lightness,
calm, the master of haste.
a lone traveller will journey all day, watching over his belongings;
yet once safe in his bed he will lose them in sleep.
the captain of a great vessel will not act lightly or hastily.
acting lightly, he loses sight of the world,
acting hastily, he loses control of himself.
a captain can not treat his great ship as a small boat;
rather than glitter like jade
he must stand like stone.
