This short but meaningful prayer by St. Ephrem of Syria, deacon (c. 306-373) is still used by both the Byzantine Catholic Church and the Orthodox Church during Lent. You can pray this whenever you’d like, but it is recommended for morning, noon, and evening.
O Lord and Master of my life, take from me the spirit of sloth, despair, lust of power, and idle talk.
But give rather the spirit of chastity, humility, patience, and love to Thy servant.
Yea, O Lord and King, grant me to see my own transgressions, and not to judge my brother, for blessed art Thou, unto ages of ages. Amen.
