Fasani was known for having a deep life of prayer and was considered to be a mystic, becoming greatly in demand as a confessor and preacher. He constantly preached popular parish missions, gave retreats and led Lenten devotions and novenas - either in his own town or wherever he was requested. It was reported by his contemporaries that he would levitate while at prayer. At the same time, he was a steadfast friend of the poor, constantly seeking out the financial support necessary for efforts to meet their needs.
