To know that you do not know is the best. To pretend to know when you do not know is a disease.
LaoziAccept disgrace willingly... Accept being unimportant... Surrender yourself humbly; then you can be trusted to care for all things. Love the world as your own self; then you can truly care for all things.
LaoziSo sometimes things are ahead and sometimes they are behind; Sometimes breathing is hard, sometimes it comes easily; Sometimes there is strength and sometimes weakness; Sometimes one is up and sometimes down. Therefore the sage avoids extremes, excesses, and complacency.
LaoziWithout opening your door, you can open your heart to the world. Without looking out your window, you can see the essence of the Tao. The more you know, the less you understand. The Master arrives without leaving, sees the light without looking, achieves without doing a thing.
Laozi
