The Sixth and Ninth Commandments work together. What the Sixth Commandment forbids in action, the Ninth Commandment forbids in thought or desire.

Prevalence of these sins : “More souls go to Hell for sins of the flesh than for any other reason.” – Our Lady to Jacinta Marto, Fatima, 1917.

Chief dangers to the virtue of chastity : Idleness, sinful curiosity, bad companions, drinking, immodest dress, indecent books, plays, movies, video games, Internet sites, TV shows and even some types of music.

Chief means of preserving the virtue of chastity : Avoid carefully all unnecessary dangers and temptations; seek God’s help through prayer, frequent confession, Holy Communion, assistance at Holy Mass and have a special devotion to the Blessed Virgin.

Many fall because they do not avoid dangers. They go to movies, watch TV shows, read magazines, visit Internet sites, play video games, or listen to
music which are offensive to the Lord. They associate too much with the opposite sex and try to excuse themselves by saying that they have no bad intentions. Good intentions alone are not sufficient. Human nature is very weak where purity is concerned, and we must keep far from all danger, or
sooner or later we shall fall.

Impure thoughts : Impure thoughts are not always sinful, but always dangerous. They become sinful when we do not try to get rid of them. Such thoughts are temptations from the devil. The best way to do get rid of such thoughts is by prayer or thinking about something else. Above all, avoid idleness. The devil has trouble tempting busy people.

Purity: Purity of heart requires modesty. Modesty is patience, decency [exercising proper conduct, speech and good taste] and discretion [being careful about what one says and does]. Modesty protects the intimate center of the person

The Sixth Commandment commands: us to be pure and modest in our behavior. Chastity in word and deed.
The Ninth Commandment commands: us be pure in thought and desire.
