The demon always rejoices when things are hidden. Thieves do not steal as much during the day; they steal more often during the night. Similarly, the demons hide within the night of concealed thoughts, and this is when they harm us.
For this reason, we should go to confession and we should not hide anything. We should repel this difficulty, because we all feel ashamed—and I first. “How will I say this?” we think, when in essence it is easy. In a split second, when a person reveals what is on his mind, he is freed, and afterwards he wonders: “What was preventing me from confessing?” It was the demon who did not want to be exposed by the light of sacred and purifying confession, who did not want you to attain forgiveness and enlightenment.
