Walking, sitting, eating, or drinking, St. Francis was always intent upon prayer. He would go alone to pray at night in churches abandoned and located in deserted places, where, under the protection of divine grace, he overcame many fears and many disturbances of mind.
~St. Francis of Assisi, Celano, First Life, Chapter XXVII (thanks to Portiuncula: the Little Portion)
St. Francis was accustomed not to pass over any visitation of the Spirit with negligence. When indeed such was offered, he followed it, and as long as the Lord would permit, he would enjoy the sweetness offered him. When, therefore, while he was pressed by some business or was intent upon a journey, he would taste the sweetest manna in frequent snatches.
