Pray before your body takes rest on your bed... If you are tempted, make the Sign (of the Cross) on your forehead reverently… for this is a known and tested weapon against the Devil.
The experience of the ages shows that the sign of the cross has great power over all a person’s actions during the entire course of his life. Therefore it is necessary to strive to root in children the habit of protecting themselves with the sign of the cross often, especially when receiving food and drink, going to bed and waking up, before departing somewhere in a vehicle, before leaving and entering any place; and they should not make the sign carelessly or according to fashion, but precisely, beginning with the forehead to the solar plexus, then to both shoulders, so that a proper cross is produced.... The sign of the cross has saved many from great dangers and afflictions.
Since self-love is the origin and mother of evil, when this is eradicated all the things which derive from it are eradicated as well. For when self-love is absent, not the slightest trace or form of evil can exist in any way at all.
There is no venom more poisonous than that of the asp or cobra, and there is no evil greater than that of self-love. The winged children of self-love are self-praise, self-satisfaction, gluttony, unchastity, self-esteem, jealousy and the crown of all these, pride. Pride can drag down not men alone, but even angels from heaven, and surround them with darkness instead of light.
