From the profound abyss of my nothingness I prostrate myself before Thee, O most Sacred, Divine and Adorable Heart of Jesus, to render Thee all the homage of love, praise and adoration of which I am capable, and to present to Thee my necessities, both spiritual and temporal, discovering to Thee as to my most perfect friend, all my miseries, my poverty, my nakedness, my infirmity, my pusillanimity, in fine, all the wounds and ulcers of my soul, begging Thee to have compassion on me and graciously to help me according to the greatness of Thy mercies, which Thou makest Thy glory to show us in our extreme necessities. O Heart all good, my only hope is in Thee. Save me, I implore Thee, by all that is most capable of moving Thee to grant this favor to me and to all those who are in the same peril of their salvation. Oh! do not allow me to perish in the deluge of my iniquities; provided that I love Thee eternally. For the rest, do what Thou willest with me and in me. Remember that Thou art all-powerful, do not permit me to be disappointed in my hopes, but grant me the request which I now make to Thee in favor of those persons afflicted with sickness or other evils. Incline Thyself, O Heart of love, to my humble prayer by which I ask Thee for the salvation of my own soul and of the souls of my parents and friends; I ask also for relief of the Souls in Purgatory, especially of those most abandoned. I ask Thee also, O Divine Heart, by the merits of those suffering Souls, for the gift of prayer, the grace never to be separated from Thee, and the grace to live and die as a true child of the Visitation, and the unworthy slave of the Sacred Heart of Jesus and Mary, whom I beseech with all my heart to strengthen me in my resolution.

I have placed all my confidence in Thee, do not reject me. I call Thee, I invoke Thee as the sovereign remedy for all my evils, the greatest of which is sin. Destroy it in me and grant me pardon for all the sins that I have committed, of which I repent with my whole heart, and ask Thy forgiveness for them.

Make then Thy sovereign power, O loving Heart, felt by me and by all hearts capable of loving Thee, especially by my parents and friends, and by all those persons who have recommended themselves to my prayers or who are praying for me, and by any for whom I have a special obligation. Assist them, I beseech Thee, according to their necessities.

O Heart full of charity, soften hardened hearts and relieve the Souls in Purgatory; be the assured refuge of those in their last agony and the consolation of all those who are afflicted or in need. In fine, O Heart of Love, be to me all in all things; but especially at the hour of my death, be the safe retreat for my poor bewildered soul. At that moment, receive it into the bosom of Thy mercy. Amen.


 I adore Thee, I love Thee, I praise Thee, I cry to Thee for mercy, I return Thee thanks, I invoke Thee and confide myself entirely to Thee, O most holy and adorable Heart of my Lord and Savior Jesus Christ, who for the salvation of us all didst submit Thyself to the rigors of Divine Justice, and didst voluntarily accept a birth accompanied with poverty, sorrow and contempt, a life of labor and contradictions, but of kindness for all, and a death full of opprobrium, confusion and sorrow, and who, in fine, for the love of those who wish to be saved through Thy divine charity, dost remain in the Blessed Sacrament of the altar to the end of time. Accomplish, O most adorable Heart, Thy wishes in my poor and miserable heart, which I dedicate and consecrate to Thee forever. Grant that it may live in the sentiments of love and gratitude which it owes Thee, that it may at all times breathe only Thy honor and glory, in order that it may expire in the waters of perfect contrition. Amen.


With all the power of my heart, I now adore Thy sovereignty, O most Sacred, Divine and Adorable Heart of Jesus, whom I wish to fear and respect with continuous attention never more to offend Thee because Thou art infinitely good. O most Sacred Heart, I love Thee and wish to love Thee above all things with all my strength and power. I detest every mortal sin and all voluntary venial sins; I hope that as we belong to Thee, who hast given birth to us on the Cross with so much pain, Thou wilt have pity on our weakness and misery and not allow us to perish.

I offer myself entirely to Thee, O Heart of love, with the intention that my whole being, my life and my sufferings may be employed in loving, honoring and glorifying Thee in time and in eternity. I love Thee, O most amiable Heart, as my sovereign good, my entire happiness and all my joy, as the sole object worthy of the love of all hearts. May my heart be reduced to cinders by the ardor and vehemence of this love, by which I renew with my whole soul all the offerings which I have made to Thee of myself. Keep me from displeasing Thee and grant me to do what is most pleasing to Thee. O Heart, Source of pure love, would that I might be all heart to Thee and all soul to adore Thee! Grant that by Thy holy grace, I may be able to love only Thee, to love in Thee and by Thee and for Thee. May my memory think only of Thee, may I have no other understanding but to know Thee, no other will or affection but to love Thee, no tongue but to praise Thee, no eye but to see Thee, no hands but to serve Thee, no feet but to seek Thee, in order that I may be able one day to love Thee without fear of losing Thee for all eternity. Amen.


The ardent desire which I have of being a good religious, O my sweet Jesus, urges me to ask of Thee to make me conformable to that life of death of the senses which Thou leadest in the Blessed Sacrament, where Thou dost render Thyself obedient until death, in a mystical manner, at the mere voice of the priest whether he be good or bad. Grant then, O my Savior, that to honor Thy obedience and annihilation in the Blessed Sacrament, I may be able to render myself humble and obedient according to the fullness of perfection marked out in our holy constitutions.

For Thee, O Jesus, I sacrifice without reserve, my liberty and my own will to Thy holy will. With my whole heart, I disavow, renounce and detest all views, repugnances, disagreements and murmurings which my will or my proud self-love may suggest to me, in all that I shall be ordered or forbidden to do. This is the pact which my heart makes with Thy Sacred Heart, O my Jesus, to do everything through love and obedience and to wish to live and die in this exercise, in which I include all that is necessary for my perfection. I beg of Thee to take charge of my heart and of everything in me that can glorify Thee for time and eternity. Amen.
