And when Florus inquired, 'But why do not you appear?' he answered, 'Because I do not even consider the question.'

The soul that companies with virtue is like an ever-flowing source. It is a pure, clear, and wholesome draught, sweet, rich and generous of its store, that injures not, neither destroys.

If you do not wish to be prone to anger, do not feed the habit; give it nothing which may tend to its increase. At first, keep quiet and count the days when you were not angry: "I used to be angry every day, then every other day: next, every two, then every three days!" and if you succeed in passing thirty days, sacrifice to the gods in thanksgiving.

Renew every day your conversation with God: Do this even in preference to eating. Think more often of God than you breathe.
