11. Everyone that desires salvation must not only avoid evil, but is obliged to do good, just as it says in the Psalm: "Depart from evil and do good" (Psalm 34:14). For example, if somebody was angry, he must not only not get angry, but also become meek; if somebody was proud, he must not only refrain from being proud but also become humble. Thus, every passion has an opposing virtue: pride — humility, stinginess — charity, lust — chastity, faintheartedness — patience, anger — meekness, hatred — love.
