If it is not right do not do it; if it is not true do not say it.

Do not act as if you were going to live ten thousand years. Death hangs over you. While you live, while it is in your power, be good.

Live not as though there were a thousand years ahead of you. Fate is at your elbow; make yourself good while life and power are still yours.

Whatever any one does or says, I must be good.

How much time he gains who does not look to see what his neighbour says or does or thinks, but only at what he does himself, to make it just and holy.

Retire into thyself. The rational principle which rules has this nature,
that it is content with itself when it does what is just, and so secures
tranquility.
