Say once a day for 9 days
By the Voice of Thy Blood, O Jesus! I would press Thee, solicit Thee, importune Thee, though Thou seemest to reject my supplications. I will not leave Thy bleeding feet until Thou hearest me. Too many graces, too many mercies have come from Thy Blood, for me not to hope, even to the end in its efficacy.
Then, O Jesus! by the Precious Blood seven times shed for the welfare of men, by each drop of that Sacred Price of our redemption, by the tears of Thy Immaculate Mother, I conjure Thee, I supplicate Thee, hear my earnest prayer.
(Mention your intentions here)
O Thou, who during all the days of Thy mortal life, consoled so many sufferings, healed so many infirmities, raised so often a sinking courage; Thou will not fail to have pity on a soul who cries to Thee from the depths of her anguish! Oh, no, it is impossible! Another sigh from my heart, and from the wound in Thine own, there will flow to me, upon a wave of Thy merciful Blood, the grace so ardently desired. O Jesus, Jesus! hasten the moment when Thou wilt change my tears into joy, my sighs into thanksgivings.
Holy Mary, Source of the Divine Blood! I conjure Thee not to lose this occasion of glorifying the Blood which made Thee Immaculate. Amen.
