The lower you descend, the higher you ascend; and when, like the psalmist, you regard yourself as nothing before the Lord (cf. Ps. 39:5), then imperceptibly you will grow great.

Why do you increase your bonds? Take hold of your life before your light grows dark and you seek help and do not find it. This life has been given to you for repentance; do not waste it in vain pursuits.
