"Oh Jesus, through the Immaculate Heart of Mary, I offer you all my prayers, works, joys and sufferings of this day. For all the intentions of thy Most Sacred Heart. In Union with the Holy Sacrifice of the Mass, throughout the world. In reparation for our sins and for all of our associates, and in particular for all the intentions of this month...(and whatever you like).
