Don Bosco’s devotion to the Sacred Heart of Jesus originated from the revelations to Saint Margaret Mary Alacoque in the monastery of Paray-le-Monial: Christ, showing his pierced Heart crowned with thorns, asked for a feast of reparation on the Friday after the Octave of Corpus Christi. Despite opposition, the cult spread because that Heart, the seat of divine love, recalls the charity manifested on the cross and in the Eucharist. Don Bosco invites young people to honour it constantly, especially in the month of June, by reciting the Crown and performing acts of reparation that obtain copious indulgences and the twelve promises of peace, mercy, and holiness.


                Devotion to the Most Sacred Heart of Jesus, which is growing every day, listen dear young people, to how it originated. There lived in France, in the monastery of the Visitation in Paray-le-Monial, a humble virgin named Margaret Alacoque, dear to God for her great purity. One day, while she was standing before the Blessed Sacrament to adore the blessed Jesus, she saw her Heavenly Spouse in the act of uncovering his breast and showing her his Most Sacred Heart, radiant with flames, surrounded by thorns, pierced by a wound, and surmounted by a cross. At the same time, she heard Him complain of the monstrous ingratitude of men and ordered her to work to ensure that on the Friday after the Octave of Corpus Christi, special worship would be given to His Divine Heart in reparation for the offences He receives in the Most Holy Eucharist. The pious virgin, filled with confusion, explained to Jesus how unfit she was for such a great undertaking, but she was comforted by the Lord to continue her work, and the feast of the Sacred Heart of Jesus was established despite the fierce opposition of her adversaries.
                There are many reasons for this devotion: 1) Because Jesus Christ offered us His Sacred Heart as the seat of His affections; 2) Because it is a symbol of the immense charity He showed especially by allowing His Most Sacred Heart to be wounded by a lance; 3) Because from this Heart the faithful are moved to meditate on the sufferings of Jesus Christ and to profess their gratitude to Him.
                Let us therefore constantly honour this Divine Heart, which, for the many and great benefits it has already bestowed upon us and will bestow upon us, well deserves all our most humble and loving veneration.

Month of June
                Those who consecrate the entire month of June to the honour of the Sacred Heart of Jesus with some daily prayer or devout act will gain seven years of indulgence for each day and a Plenary indulgence at the end of the month.

Chaplet to the Sacred Heart of Jesus
                Intend to recite this Crown to the Divine Heart of Jesus Christ to make reparation for the outrages He receives in the Most Holy Eucharist from infidels, heretics, and bad Christians. Say it alone or with other people gathered together, if possible before an image of the Divine Heart or before the Blessed Sacrament:
                V. Deus, in adjutorium meum intende (O God, come to my aid).
                R. Domine ad adjuvandum me festina (Lord, make haste to help me).
                Glory be to the Father, etc.

                1. O most lovable Heart of my Jesus, I humbly adore your sweet kindness, which you show in a special way in the Divine Sacrament to souls who are still sinners. I am sorry to see you so ungratefully repaid, and I intend to make up for the many offences you receive in the Most Holy Eucharist from heretics, infidels, and bad Christians.
                Our Father, Hail Mary, and Glory be.

                2. O most humble Heart of my Sacramental Jesus, I adore your profound humility in the Divine Eucharist, hiding yourself for our love under the species of bread and wine. I beg you, my Jesus, to instil this beautiful virtue in my heart; meanwhile, I will endeavour to make reparation for the many offences you receive in the Most Holy Sacrament from heretics, infidels, and bad Christians.
                Our Father, Hail Mary, and Glory be.

                3. O Heart of my Jesus, so eager to suffer, I adore those desires so ardent to encounter your most painful Passion and to subject yourself to those wrongs foreseen by you in the Blessed Sacrament. Ah, my Jesus! I truly intend to make reparation with my very life; I would like to prevent those offences which you unfortunately receive in the Most Holy Eucharist from heretics, infidels, and bad Christians.
                Our Father, Hail Mary, and Glory be.
               
4. O most patient Heart of my Jesus, I humbly venerate your invincible patience in enduring so many pains on the Cross and so many abuses in the Divine Eucharist for love of me. O my dear Jesus! Since I cannot wash with my blood those places where you were so mistreated in both Mysteries, I promise you, O my Supreme Good, to use every means to make reparation to your Divine Heart for the many outrages you receive in the Most Holy Eucharist from heretics, infidels, and bad Christians.
                Our Father, Hail Mary, and Glory be.

                5. O Heart of my Jesus, most loving of our souls in the admirable institution of the Most Holy Eucharist, I humbly adore that immense love which you bear us in giving us your Divine Body and Divine Blood as our nourishment. What heart is there that should not be consumed at the sight of such immense charity? O my good Jesus, give me abundant tears to weep and make reparation for the many offences you receive in the Most Holy Sacrament from heretics, infidels, and bad Christians.
                Our Father, Hail Mary, and Glory be.

                6. O Heart of my Jesus, thirsting for our salvation, I humbly venerate that most ardent love which prompted you to perform the ineffable Sacrifice of the Cross, renewing it every day on the Altars in the Holy Mass. Is it possible that the human heart, filled with gratitude, should not burn with such love? Yes, alas, my God; but for the future I promise to do all I can to make reparation for the many outrages you receive in this Mystery of love from heretics, infidels and bad Christians.
                Our Father, Hail Mary, and Glory be.

                Whoever recites even the above 6 Our Fathers, Hail Marys, and Glory’s before the Blessed Sacrament, the last Our Father, Hail Mary, and Glory be, being said according to the intention of the Supreme Pontiff, will gain 300 days of Indulgence each time.

Offered to the Most Sacred Heart of Jesus before His Holy Image
                I, NN., to be grateful to You and to make reparation for my infidelities, I give You my heart and consecrate myself entirely to You, my beloved Jesus, and with your help I resolve never to sin again.

                Pope Pius VII granted one hundred days of indulgence once a day, reciting it with a contrite heart, and a plenary indulgence once a month to those who recite it every day.


Prayer to the Most Sacred Heart of Mary
                God save you, Most August Queen of Peace, Mother of God; through the Most Sacred Heart of your Son Jesus, Prince of Peace, may His wrath be appeased and may He reign over us in peace. Remember, O Most Pious Virgin Mary, that it has never been heard in the world that anyone who implores your favours has been rejected or abandoned by you. Encouraged by this confidence, I present myself to you: do not despise my prayers, O Mother of the Eternal Word, but hear them favourably and grant them, O Clement, O Pious, O Sweet Virgin Mary.
                Pius IX granted an indulgence of 300 days each time this prayer is recited devoutly, and a plenary indulgence once a month to those who recite it every day.

                O Jesus, burning with love,
                I never wanted to offend You;
                O my sweet and good Jesus,
                I never want to offend You again.

                Sacred Heart of Mary,
                Save my soul.
                Sacred Heart of my Jesus,
                Make me love you more and more.

                To you I give my heart,
                Mother of my Jesus – Mother of love.
