Tao Te Ching Chapter 26
The Solid is the root of the light;
The Quiescent is the master of the Hasty.
Therefore the Sage travels all day
Yet never leaves his provision-cart.
In the midst of honor and glory,
He lives leisurely, undisturbed.
How can the ruler of a great country
Make light of his body in the empire (by rushing about)?
In light frivolity, the Center is lost;
In hasty action, self-mastery is lost.
