The wind drives across heaven:
The image of the Taming Power of the Small.
Thus the superior man refines the outward aspect of his nature.

The wind can indeed drive the clouds together in the sky; yet, being nothing but air, without solid body, it does not produce great or lasting effects. So also an individual, in times when he can produce no great effect in the outer world, can do nothing except refine the expression of his nature in small ways.
