If devotion to the Blessed Virgin is necessary for all men simply to work out their salvation, it is even more necessary for those who are called to a special perfection. I do not believe that anyone can acquire intimate union with our Lord and perfect fidelity to the Holy Spirit without a very close union with the most Blessed Virgin and an absolute dependence on her support.
Louis de MontfortFrom day to day, from moment to moment, she increased so much this twofold plenitude that she attained an immense and inconceivable degree of grace. So much so, that the Almighty made her the sole custodian of his treasures and the sole dispenser of his graces. She can now ennoble, exalt and enrich all she chooses. She can lead them along the narrow path to heaven and guide them through the narrow gate to life. She can give a royal throne, sceptre and crown to whom she wishes.
Louis de Montfort[Mary] is the safest, easiest, shortest and most perfect way of approaching Jesus and will surrender themselves to her, body and soul, without reserve in order to belong entirely to Jesus.
Louis de MontfortWe must conclude that, being necessary to God by a necessity which is called "hypothetical", (that is, because God so willed it), the Blessed Virgin is all the more necessary for men to attain their final end. Consequently we must not place devotion to her on the same level as devotion to the other saints as if it were merely something optional.
Louis de MontfortChosen soul, how will you bring this about? What steps will you take to reach the high level to which God is calling you? The means of holiness and salvation are known to everybody, since they are found in the Gospel; the masters of the spiritual life have explained them; the Saints have practiced them...These means are: sincere humility, unceasing prayer, complete self-denial, abandonment to Divine Providence, and obedience to the will of God.
