Looking at the Heart of Jesus say:
O Heart of Jesus, sweet, tender, peaceful, compassionate, sincere, charitable, and faithful; O furnace of Love! O treasure of all Graces! O amiable and endless source of all the sorrows of love that ever did, do, or will enter the hearts of men, infuse into my miserable heart all that sorrow, grief, affliction, and sighing, which you fostered in the hearts of so many holy penitents.
As my heart has sinned as much as theirs, why should it not be filled with as much sorrow? May a holy contrition emanate from the heart of Jesus into mine, with dispositions to receive it. May tears, O Jesus, flow in abundance, accompanied with sorrow, shame, hatred, and love. A Savior so lovely and so loving, but so little loved, and so much offended.
Oh, my poor heart, foul, libertine, impious, ungrateful, envious, covetous, sensual, choleric, revengeful, slothful, negligent, miserable, earthly heart, so sensible to everything that relates to the world, and so insensible to your own disorders; so yielding to your own passions, and so hardened to all divine inspirations. Oh, wicked, treacherous heart; heart of stone, nay, harder than the very rocks, for they afford the richest fountains of water, and you, with so much difficulty, afford a few drops of tears, even at the very season when you see your Savior covered with streams of blood, shed in His agony and bloody sweat in the garden, in His unmerciful scourging, and in His crucifixion for your sake.
What a difference between hearts! Between Your Heart, O Jesus, and mine! O my Jesus, grant that my heart might become like yours by grace. Let our hearts be no longer two, but one – one faithful, devout, gracious, charitable, and holy heart; this O my Savior, shall henceforth be my whole study and endeavor – to entertain nothing in my heart but what finds place in yours, namely humility, purity, patience, fortitude, charity, and love. Nothing but Jesus and His Love; my heart is no longer mine: it entirely belongs to Jesus.
