MARY, thou mystical rose of purity, my heart rejoices with thine at the glorious triumph which thou didst gain over the infernal serpent by thy immaculate conception, and because thou wast conceived without stain of original sin. I thank and praise with my whole heart the ever-blessed Trinity, who granted thee this glorious privilege; and I pray thee to obtain for me strength to overcome all the wiles of the infernal foe, and never to stain my soul with sin. Be thou mine aid; make me, by thy protection, victorious over the common foe of our eternal welfare.
