The kindness of God provides us with all the grace and knowledge we need to arrive at that eternal Beatitude to which he calls each one of us. Occasionally, he even bestows extraordinary apprehensions on certain holy mystics, in order to give us a glimpse of realities beyond our everyday perceptions, thereby inspiriting us to run in the paths of his goodness toward our perfect fulfillment . . .

The first book was published in French as Manuscript on Purgatory by Sister M. de L. C. The second book is by St. Catherine of Genoa, Treatise on Purgatory. At the end is a Note about Revelation vs. Spiritism, which includes a quotation by Fr. Gabriele Amorth, world-renowned exorcist, on the dangers of spiritism.

Both of these manuscripts are private revelations and hence are not binding on the faithful, but both of these documents have been examined by theological experts and found to be free of doctrinal error.
