Chapter 13
On Reading and Memorizing the Psalter
Memorizing the Psalter is a good deed. Fill yourself with prayerful thoughts and feelings. The holy fathers urged this on everyone. And they advised reading the psalms not only in prayer services, but also separately. You can read psalms even among your tasks, especially when you are moving from one place to another. But to maintain thoughts of God and feeling toward Him in the midst of work, it is best to become accustomed to a short prayer.
