Creating without claiming, Doing without taking credit, Guiding without interfering, This is Primal Virtue.
...The sage works without recognition. He achieves what has to be done without dwelling on it. He does not try to show his knowledge.
In the pursuit of learning, every day something is acquired. In the pursuit of Tao, every day something is dropped.
To realize that you do not understand is a virtue; Not to realize that you do not understand is a defect.
