Total Consecration to Mary

O Immaculata, Queen of heaven and earth, Refuge of sinners and our Mother, who love us so much and to whom God has entrusted the whole order of mercy!
I, N., a faithless sinner, cast myself at Your feet and implore You from the depths of my heart: Deign to accept me wholly and entirely as Your possession and Your property. Do with me as You please, with all the faculties of my soul and body, with my whole life, my death and my eternity. Dispose entirely of me as You will, that what is said of You may be fulfilled: "She will crush the head of the serpent." – and likewise: "You alone have conquered all heresies throughout the world."
Make me an instrument in Your hands to serve You, to increase Your glory as much as possible in so many fallen and lukewarm souls. Thus the gentle kingdom of the Most Sacred Heart of Jesus will spread ever more. For wherever You enter, You obtain the grace of conversion and sanctification, for all graces come to us from the Most Sacred Heart of Jesus only through Your hands.
Grant me to praise You, O most holy Virgin, and give me power against Your enemies. Amen.
