2528 "Everyone who looks at a woman lustfully has already committed adultery with her in his heart" (⇒ Mt 5:28).
2529 The ninth commandment warns against lust or carnal concupiscence.
2530 The struggle against carnal lust involves purifying the heart and practicing temperance.
2531 Purity of heart will enable us to see God: it enables us even now to see things according to God.
2532 Purification of the heart demands prayer, the practice of chastity, purity of intention and of vision.
2533 Purity of heart requires the modesty which is patience, decency, and discretion. Modesty protects the intimate center of the person.
