In the name of the Father, and of the Son, and of the Holy Ghost. Amen.
O my God, I thank Thee for having preserved me this day, and I beseech Thee to vouchsafe to preserve me also during this night, and to protect me from all evil. I take this repose in order to please Thee, and I intend to love and praise Thee each moment that I breathe, as the Saints and Elect praise and love Thee in Heaven. Mary, my Mother, bless me and protect me under Thy mantle. My Angel Guardian, and all my Holy Patrons, intercede for me.
Then say three Hail Marys in honour of the Immaculate Conception, adding after each: “By Thy pure and Immaculate Conception, O Mary, make my body pure and my soul holy. My Mother, preserve me this day from mortal sin.”
