A long-time after the Lord had already granted me many of the favors I’ve mentioned and other very lofty ones, while I was in prayer one day, I suddenly found that, without knowing how, I had seemingly been put in hell. I understood that the Lord wanted me to see the place the devils had prepared there for me and which I merited because of my sins…
What I felt, it seems to me, cannot even begin to be exaggerated; nor can it be understood. I experienced a fire in the soul that I don’t know how I could describe. The bodily pains were so unbearable that though I had suffered excruciating ones in this life and according to what doctors say, the worst that can be suffered on earth… these were all nothing in comparison with the ones I experienced there. I saw furthermore that they would go on without end and without ever ceasing.
This, however, was nothing next to the soul’s agonizing: a constriction, a suffocation, an affliction so keenly felt and with such a despairing and tormenting unhappiness that I don’t know how to word it strongly enough… I felt myself burning and crumbling, and I repeat the worst was that interior fire and despair.
