Yesterday was the feast of St. Louis Marie Grignon de Montfort, whose book "True Devotion to Mary" is one of the classics on Marian spirituality. This words have had a profound impact on the Church affecting millions of people from the top (Pope St. John Paul II) all the way down (me). His profound theology of the Blessed Virgin shows in his prayers, but even more apparent is his devotion. So though it might be a bit long, it is worth praying St. Louis' own pray...
A Prayer to Mary
Hail Mary, beloved Daughter of the Eternal Father. Hail Mary, admirable Mother of the Son. Hail Mary, faithful Spouse of the Holy Ghost. Hail Mary, my Mother, my loving Mistress, my powerful sovereign. Hail, my joy, my glory, my heart and my soul. Thou art all mine by mercy, and I am thine by justice. But I am not yet sufficiently thine. I now give myself wholly to thee without keeping anything back for myself or others. If thou seest anything in me which does not belong to thee, I beseech thee to take it and make thyself the absolute Mistress of all that is mine.
Destroy in me all that may displease God; root it up and bring it to nought. Place and cultivate in me everything that is pleasing to thee. May the light of thy faith dispel the darkness of my mind. May thy profound humility take the place of my pride; may thy sublime contemplation check the distractions of my wandering imagination. May the continuous sight of God fill my memory with His Presence; may the burning love of thy heart inflame the lukewarmness of mine. May thy virtues take the place of my sins; may thy merits be my only adornment in the sight of God and make up for all that is wanting in me. Finally, dearly beloved Mother, grant, if it be possible, that I may have no other spirit but thine to know Jesus, and His Divine Will; that I may have no other soul but thinke to praise and glorify God; that I may have no other heart but thine to love God with a love as pure and ardent as thine.
I do not ask thee for visions, revelations, sensible devotions, or spiritual pleasures. It is thy privilege to see God clearly, it is thy privilege to enjoy heavenly bliss; it is thy privilege to triumph gloriously in heaven at the right hand of thy Son and to hold absolute sway over angels, men, and demons.
It is thy privilege to dispose of all the gifts of God, just as thou willest. Such, O heavenly Mary, the 'best part', which the Lord has given thee, and which shall never be taken away from thee--and this thought fills my heart with joy. As for my part here below, I wish for no other than that which was thine, to believe sincerely without spiritual pleasures, to suffer joyfully without human consolation, to die continually to myself without respite, and to work zealously and unselfishly for thee until death, as the humblest of thy servants. The only grace I beg thee, for me, is that every moment of the day, and every moment of my life, I may say, "Amen, so be it, to all that thou art doing in heaven. Amen, so be it, to all thou didst do while on earth. Amen, so be it, to all thou art doing in my soul," so that thou alone mayest fully glorify Jesus in me for time and eternity. Amen.
