I remember when I was in grade school, I heard a story of someone in Purgatory who appeared to a friend and asked for prayers. I vividly remember that he left a burned hand mark in the wooden desk. I am so glad I came across this priest's blog and the story again! It is amazing how some things leave such a vivid impression (no pun intended) on the mind of a child. Let this be a reminder to us that we should strive for perfection ourselves and pray for the poor souls in Purgatory. See the attached link for the story.
