You go to the tomb of St. Francis in Assisi and they built a wonderful cathedral. There's no atmosphere in the cathedral, and you go there just next to the sarcophagus and his being is so strong. So sometimes going to places will be helpful. It is a strength of faith of the person that heals him; but still, healing is performed by angels who have become used to being present in that spot. Healing is the victory of spirit over matter.
