St. Teresa Margaret of the Sacred Heart was heroic in her charity and compassion, especially for the sick in the infirmary of the Discalced Carmelite monastery of Florence. When one of the nuns who was mentally infirm became quite insane, St. Teresa Margaret asked to be allowed to care for the nun, although it was terrifying. The Saint would kneel and pray before a statue of the Blessed Mother every time she would need to enter the patient's locked room.
