The great Tao flows everywhere. All things are born from it, yet it doesn't create them. It pours itself into its work, yet it makes no claim. It nourishes infinite worlds, yet it doesn't hold on to them. Since it is merged with all things and hidden in their hearts, it can be called humble. Since all things vanish into it and it alone endures, it can be called great. It isn't aware of its greatness; thus it is truly great.
Don't imagine that you'll discover {the truth} by accumulating more knowledge. Knowledge creates doubt, and doubt makes you ravenous for more knowledge. You can't get full eating this way.
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.
