A quick prayer, since it's the Lord's Day.
O All-holy Lady Theotokos, light of my darkened soul, my hope, my shelter, my refuge, my consolation and my joy: I thank thee that thou hast accounted me worthy, although unworthy, to be a partaker of the immaculate Body and precious Blood of thy Son. But do thou, who gavest birth to the true Light, enlighten the mental eyes of my heart; O thou who didst bear the fountain of immortality, quicken thou me who lie dead in sin. O compassion-loving Mother of the merciful God, have mercy upon me, and grant me humility and contrition of heart, and meekness in my thoughts, and deliverance from the bondage of my vain imaginings. And account me worthy, even unto my last breath, to receive without condemnation the sanctification of the immaculate Mysteries, unto the healing of both soul and body. And grant unto me tears of repentance and confession, that I may hymn thee and glorify thee all the days of my life: for blessed and glorified art thou unto all ages.
