The Tao's principle is spontaneity.
In the pursuit of learning, every day something is acquired. In the pursuit of Tao, every day something is dropped.
The sage avoids extremity, excess, and extravagance.
If the sage wants to stand above people, he must speak to them from below. If he wants to lead people, he must follow them from behind.
Spokes unite in the hub of a wheel.
The Tao that can be spoken is not the true Tao.
