O Mary, the purest of Virgins! terrified at my weakness and at the dangers that surround me, I recommend to thy loving care with all confidence the chastity of my soul and body. Permit me not, O Queen of the Angels, to be defiled by the least stain after having been adorned with purity and innocence, like a vessel of honour and glory. Banish from my heart all sensual desires, evil thoughts, and irregular affections. To thy love, O my good Mother, do I confide my heart; purify it, render it worthy to be offered to thy Beloved Son, that, having here on earth imitated thee in the most beautiful of thy virtues, I may enjoy with thee for ever in heaven the happiness promised to the clean of heart. Amen.
