Be careful not to feel toward truly evil people the way most people feel toward each other.
Take heed lest at any time thou stand so affected, though towards unnatural evil men, as ordinary men are commonly one towards another.
You must also consider this: many things trouble and irritate you without you realizing it. You're not prepared for them with patience because they don't usually get called 'pain.' But they really are the same as pain — like restless sleep, suffering from heat, or losing your appetite. When any of these things make you unhappy, remind yourself: 'Pain has beaten me. My courage has failed.'
This also thou must consider, that many things there be, which oftentimes unsensibly trouble and vex thee, as not armed against them with patience, because they go not ordinarily under the name of pains, which in very deed are of the same nature as pain; as to slumber unquietly, to suffer heat, to want appetite: when therefore any of these things make thee discontented, check thyself with these words: Now hath pain given thee the foil; thy courage hath failed thee.
