Do not even think of doing what ought not to be done.
The oldest, shortest words - 'yes' and 'no' - are those which require the most thought.
Let no one persuade you by word or deed to do or say whatever is not best for you.
Declining from the public ways, walk in unfrequented paths.
Do not despise anyone: an atom shadowing.
Let a man use great reverence and manners to himself.
