To see what is right and not to do it is want of courage, or of principle.

He who rules by moral force is like the pole star, which remains in place while all the lesser stars do homage to it.

If one learns from others, but does not think, one will be bewildered. If, on the other hand, one thinks but does not learn from others, one will be in peril.

It does not matter how slowly you go as long as you do not stop.

Eat at your own as you would the table of a king.

Unify your attention. Do not listen with your ears, but with your mind. Do not listen with your mind but with your essence.

To take what you know for what you know, and what you do not know for what you do not know, that is knowledge indeed.
