As those who are influenced by human and natural love have their minds and hearts constantly fixed on the objects of their affections; as they speak often in their praise, and when absent lose no opportunity of expressing by letters this affection for them, and cannot even pass a tree without inscribing on the bark the name of their beloved: so those who are possessed of Divine love have their minds and hearts constantly turned toward the Divine object of their love; they are ever thinking of Him, they long after Him; they aspire to Him, and frequently speak of Him; and, were it possible, would engrave in the hearts of all mankind the Name of their beloved Jesus.
--St. Francis of Sales
