By Saint Louis de Montfort
The soul of Mary will be communicated to you to glorify the Lord. Her spirit will take the place of yours to rejoice in God, her Savior, but only if you are faithful to the practices of this devotion.
As St. Ambrose says, "May the soul of Mary be in each one of us to glorify the Lord! May the spirit of Mary be in each one of us to rejoice in God!" "When will that happy day come," asks a saintly man of our own day whose life was completely wrapped up in Mary, "when God's Mother is enthroned in men's hearts as Queen, subjecting them to the dominion of her great and princely Son? When will souls breathe Mary as the body breathes air?"
When that time comes wonderful things will happen on earth. The Holy Spirit, finding his dear Spouse present again in souls, will come down into them with great power. He will fill them with his gifts, especially wisdom, by which they will produce wonders of grace. My dear friend, when will that happy time come, that age of Mary, when many souls, chosen by Mary and given her by the most High God, will hide themselves completely in the depths of her soul, becoming living copies of her, loving and glorifying Jesus?That day will dawn only when the devotion I teach is understood and put into practice.
Ut adveniat regnum tuum, adveniat regnum Mariae:
"Lord, that your kingdom may come, may the reign of Mary come!"
