Since Satan can do nothing to Mary, he can do nothing to us when we are united to her.
When we fervently remember that we are children of Mary and fly to her at the first sign of temptation, then we will not even fall into sin. Then the demons will also say of us, "Alas! We can do naught for She Who is without stain defends him!"
"O Scapular, how many souls you snatch from us." - Fallen angels forced to cry out after a great public conversion.
"The inner life of another that is known to God alone becomes to a much less degree open to us through friendship. It partially fills the desire of our incomplete, lonely hearts for completeness in another. Friendship brings out the best in a person through forgetfulness of self." - St. Thomas Aquinas
O Mary, powerful Virgin, Thou art the mighty and glorious Protector of the Church. Thou art the Marvelous Help of Christians. Thou art Terrible as an Army set in Battle Array. Thou alone hast destroyed every heresy in the entire Church. In the midst of my anguish, my struggles and my distress, Defend me from the power of the enemy, And at the hour of my death, Receive my soul into Paradise. Amen
