Verse 30 of The Tao
A good traveler has no fixed plans
and is not intent upon arriving.
A good artist lets his intuition
lead him wherever it wants.
A good scientist has freed himself of concepts
and keeps his mind open to what is.
Thus the Master is available to all people
and doesn't reject anyone.
He is ready to use all situations
and doesn't waste anything.
This is called embodying the light.
What is a good man but a bad man's teacher?
What is a bad man but a good man's job?
If you don't understand this, you will get lost,
however intelligent you are.
It is the great secret.
