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.
