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:
Fr. Chris Alar gives inspiring stories to show the Rosary is from Heaven, is Biblical, and focuses on Jesus. This is Part 2, presented after his talk about the Rosary being Biblical in Part 1.
Jesus said: Do not be absorbed in your misery — you are still too weak to speak of it — but, rather, gaze on My Heart filled with goodness, and be imbued with My sentiments. … when you feel your strength failing, if you come to the fountain of mercy to fortify your soul, you will not grow weary on your journey (Diary, 1486).
