My experience didn't get into the book, but was profound for me. It was the last day of our mission tour and my roommate and I were expecting the group to come to our room momentarily for the morning rosary. I thought to make a quick call to clear the room, so I said "In the name of the Christ, I call to Archangel Michael and Lord Zadkiel to clear our room of all energies and entities not of the Light, not of the Christ." My roommate, who had been experiencing a new inner sight during this trip, suddenly whirled around from her packing and said "They're coming, they're coming! The angels are swooping around the room!" I was amazed, as my call had seemed to me almost casual and perfunctory, and I don't see the visual manifestations when I pray. So it was a wonderful demonstration for me of how the angels really are waiting for our calls and respond immediately!
