When the wind blows,the grass bends.
Heaven gives long life to the just and the intelligent.
Things have their roots and branches. Affairs have their beginnings and their ends. To know what is first and what is last will lead one near the Way.
To know that one knows what one knows, and to know that one doesn't know what one doesn't know, there lies true wisdom.
It does not matter how slowly you go as long as you do not stop.
People with virtue must speak out; People who speak are not all virtuous.
