Alban Butler, The Lives of the Fathers, Martyrs…
“ If the spirit of prayer was that virtue by which our saint was admitted to the familiar intercourse with God, was the key which unlocked to him the treasure of all other virtues and graces, and was the continual comfort, support, and light of his soul, and the constant advancement of its supernatural life in his mortal pilgrimage, this spirit was itself founded in the most perfect self-denial. The Holy Ghost never communicates himself, by the infusion of this grace, but to a heart that is entirely dead to itself and its passions, and crucified to the world. ”
