A wrongdoer is often a man who has left something undone, not always one who has done something.

Choose not to be harmed and you won't feel harmed. Don't feel harmed and you haven't been.

While you live, while it is in your power, be good.

Observe the movements of the stars as if you were running their courses with them, and let your mind constantly dwell on the changes of the elements into each other. Such imaginings wash away the filth of life on the ground.
