Ye great teachers: listen to what you say!

Nature knows no pause in progress and development, and attaches her curse on all inaction.

Lamps make oil-spots and candles need snuffing; it is only the light of heaven that shines pure and leaves no stain.

The wealth that cannot be administered is a burden.

Whoever wishes to keep a secret must hide the fact that he possesses one.

No one should be rich except those who understand it.

All men would be masters of others, and no man is lord of himself.
