"There are persons advanced in the ways of God, who are, as the result of an illness, inclined to exceptional irritability. They are like people badly dressed, because their illness increases, as it were tenfold, the painful impression produced by contradictions, and sometimes the latter are incessant. There may be great merit in this struggle, and great patience in seeming impatience."

Fr. Reginald Garrigou-LaGrange, The Three Ages of the Interior Life
