Before celebrating the Sacrament of Penance, one should
prepare oneself with an examination of conscience, which involves reflecting prayerfully on one's thoughts, words, and deeds in order to identify any sins.

Beatitudes. Below are a few examples of Examinations of Conscience that
can help you prepare for the Sacrament.
