Two Ways (plus many more, I am sure).
O Mother of God, accept this Rosary as a sign of my love and devotion to you.
I beg you to intercede for me with your Divine Son, and grant the favor I so earnestly desire.
O Blessed Virgin, remember your faithful servant by hearing my prayers and obtaining my petition.
O Most Holy Queen of the Rosary, pray for me.
Prayer Before the Rosary
Queen of the Holy Rosary, you have deigned to come to Fatima to reveal to the three shepherd children the treasurers of grace hidden in the Rosary. Inspire my heart with a sincere love of this devotion, in order that by meditating on the Mysteries of our Redemption, which are recalled in it, I may be enriched with its fruits and obtain peace for the world, the conversion of sinners and of Russia, the intentions of our Holy Father, Pope Benedict, and the favor which I ask of you in this Rosary. (Mention Request)
I ask it for the greater glory of God, for your own honor, and for the good of souls, especially for my own. Amen.
