I have never seen one who really loves goodness or one who really hates wickedness. One who really loves goodness will not place anything above it. One who really hates wickedness will practice goodness in such a way that wickedness will have no chance to get at him. Is there anyone who has devoted his whole strength to doing good for even as long as a single day? I have not seen anyone give up such an attempt because he had not the strength to go on. Perhaps there is such a case, but I have never seen it.

What you know, you know, what you don't know, you don't know. This is true wisdom.

A knight whose heart is set upon the Way, but who is ashamed of wearing shabby clothes and eating coarse food, is not worth calling into counsel.

The Master said, I set my heart on the Way, base myself on virtue, lean upon benevolence for support and take my recreation in the arts.

We can know a person by observing his behaviour, understanding the reasons for his actions and ascertaining his intentions. If we do this, how can we not know him?
