According to the Method of St. Francis of Assisi
Preparatory Prayer
O most merciful Jesus, with a contrite heart and penitent spirit, I bow down in profound humility before Thy divine majesty. I adore Thee, I hope in Thee, I love Thee above all things. I am heartily sorry for having offended Thee, my Supreme and Only God. I resolve to amend my life, and although I am unworthy to obtain mercy, yet the sight of Thy cross, on which Thou didst die, inspires me with hope and consolation. I will, therefore, meditate on Thy Passion in company with Thy sorrowful Mother and my guardian angel, with the intention of promoting Thy honor and saving my soul.
I desire to gain all the indulgences granted for for this holy exercise for myself and for the Poor Souls in Purgatory. O merciful Redeemer, who has said, "And I, if I be lifted from the earth, will draw all things to Myself", draw my heart and my love to Thee, that I may perform this devotion as perfectly as possible, and that I may live and die in union with Thee.
Amen.
