First published in 1943, Difficulties in Mental Prayer has guided generations of Catholics through the everyday obstacles of prayer: distractions, dryness, discouragement, and the struggle to persevere. It remains both an accessible introduction and a lasting source of encouragement; and is less a manual of instructions than an invitation: to begin, to continue, and never to lose heart in prayer. With clarity and warmth, Dom Eugene Boylan offers much practical wisdom that has made this classic beloved by Catholics worldwide.
