This as it seems to me, is what passed:
The Lord said to me,
“My Divine Heart is so passionately in love with men that it can no longer contain within itself the flames of its ardent charity. It must pour them out by thy means, and manifest itself to them to enrich them with its precious treasures, which contain all the graces of which they have need to be saved from perdition. I have chosen thee as an abyss of unworthiness and ignorance to accomplish so great a design, so that all may be done by Me.”

He demanded my heart, and I supplicated Him to take it. He did so, and put it into His own Adorable Heart, in which He allowed me to see it as a little atom being consumed in that fiery furnace. Then, drawing it out like a burning flame in the form of a heart, He put it into the place whence He had taken it saying:

“Behold, My beloved, a precious proof of My love. I inclose in thy heart a little spark of the most ardent flame of My love, to serve thee as a heart and to consume thee till they last moment. Until now thou hast taken only the name of My slave; henceforth thou shalt be called the well-beloved disciple of My Sacred Heart.”

He unfolded to me the inexplicable wonders of His pure love, and to what an excess He had carried it for the love of men, from whom He had received only ingratitude.

“This is much more painful to Me than all I suffered in My Passion. If men rendered Me some return of love, I should esteem little all I have done for them, and should wish, if such could be, to suffer it over again; but they meet My eager love with coldness and rebuffs. Do you, at least console and rejoice Me, by supplying as much as you can for their ingratitude.”

Behold, this Heart which has so loved men that it has spared nothing, even to exhausting and consuming itself, in order to testify its love. In return, I receive from the greater part only ingratitude, by their irreverence and sacrilege, and by the coldness and contempt they have for Me in this sacrament of love. And what is most painful to Me is that they are hearts consecrated to Me.

It is for this reason I ask thee that the first Friday, after the octave of the Blessed Sacrament be appropriated to a special feast, to honor My Heart by communicating on that day, and making reparation for the indignity that it has received. And I promise that My Heart shall dilate to pour out abundantly the influences of its love on all that will render it this honor or procure its being rendered.

It is for Thy love alone, O my God, that I submit to write this in obedience, and I ask Thy pardon for the resistance I have made. But as no one except Thyself can know the extent of the repugnance that I feel, so it is only Thou that canst give me the strength to overcome it.

I receive this order as coming from Thee; and by its fulfillment I wish to punish the excessive joy and precaution that I have taken to follow the great inclination that I have always had to bury myself in eternal oblivion of creatures. O my Sovereign Good, may I write nothing but for Thy Greater glory and my still greater confusion!

I proceed through obedience, O my God, without any other design than that of satisfying Thee by the martyrdom which I suffer in penning these lines, every word of which seems to me a sacrifice. But mayest Thou be glorified by it eternally!
