Turn to any page of St. Faustina's Diary, and you'll find spiritual gems. Like this one:I was in a misty place full of fire in which there was a great crowd of suffering souls. They were praying fervently, but to no avail, for themselves; only we can come to their aid (Diary, 20).

Saint Faustina prayed the Rosary every day. One time, she wrote:… [One time] I saw many demons. One of these tried to vex me; taking the form of a cat, he kept throwing himself onto my bed and on my feet, and he was quite heavy, as if [weighing] a ton. I kept praying the rosary all the while, and toward dawn these beings vanished, and I was able to get some sleep. (412)

Turn to any page of St. Faustina's Diary, and you'll find spiritual gems like this one:Suddenly, I found myself in a strange cottage where an elderly man was dying amidst great torments. … When I began to pray …  The soul became calm and, filled with trust, rested in the Lord. At the same moment, I found myself again in my own room. How this happens... I do not know. (Diary of Saint Maria Faustina Kowalska, 1797)
