A good runner leaves no track.
A good speech leaves no flaws for attack.
A good reckoner makes use of no counters.
A well shut door makes use of no bolts,
And yet cannot be opened.
A well-tied knot makes use of no rope,
And yet cannot be untied.
Therefore the Sage is good at helping men;
For that reason there is no rejected person.
He is good at saving things;
For that reason there is nothing rejected.
This is called stealing the Light.
