An Introduction to the Devout Life continues, with a recommendation of a simple method of evening prayer combined with an examination of conscience.
Seeing as people nowadays often don’t really believe in sin, examinations of conscience have often gone by the wayside. But even if you were interested in business profits or sports success instead of God, you would surely want to examine how you’ve acted during a day, what has been done well and what hasn’t, and what needs to be changed. So surely, there’s nobody who wouldn’t benefit from such a summing up. (Before your mind does it to you, instead, and you end up laying awake replaying events behind your eyelids.)
