These three letters contrast dawn for most people with midnight for devoted ascetics, portraying the night as an ideal time for spiritual solitude and reflection. In this silence the soul avoids harmful sensory distractions, communes alone with God, examines and repents of sins, establishes limits to prevent sin, and seeks God's assistance to fulfill its spiritual aims. The passage concludes as a fraternal appeal for the recipient's holy prayers, asking deliverance from the evils and unreasonable people of the age, freedom from sin, separation from the enemy, and the grace to perceive God with a pure heart.
