When I pray the Rosary, I conclude each Hail Mary with a little tack-on of what I ask she will pray, such as, “pray for us sinners, now and at the hour of our death, that we might be perfectly united with the Sacred Heart of Jesus. Amen.” Things like that.
The way I can keep focused to a significant extent during the Meditations is I bring back the end of the Hail Marys to the Meditation by praying something like, “pray for us sinners, now and at the hour of our death. Pray for us that as you traveled about 80 miles of a long and hard journey to Elizabeth while you yourself were pregnant, and attended an elderly woman for three months, in such a way, I too may gain the grace, strength and will to devote myself to my neighbors. Amen.”
I conclude each of the Hail Marys with a prayer of my own, short or long, some devoted to my own life or the lives of people around me or the world, and many focused on the readings of the Meditations.
I pray the Our Fathers in the same way, and I pray all the prayers slowly so that the full meaning of each line sinks into me and becomes its own specific prayer about something in particular.
Unfortunately, taking so much time in my meditation makes praying the Rosary such a long process for me (2 hours) that I usually don’t get around to praying it in the first place :(. Each time I do pray it, though, it is incredibly meaningful. I wish I could be quicker and yet still experience the same level of meaning and spiritual impact that I do when I pray it the long way.
