Between his breviary pages, Pope Francis keeps his Grandmother Rosa's letters and her last words to her grandchildren before she died. She said that in times of sadness, trouble or loss, to look to the tabernacle, "where the greatest and noblest martyr is kept," and to Mary at the foot of the cross so that they may "let fall a drop of salve on the deepest and most painful wounds."
