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.
