[The prayer closet] is the battlefield of the Church; its citadel; the scene of heroic and unearthly conflicts. The closet is the base of supplies for the Christian and the Church. Cut off from it there is nothing left but retreat and disaster. The energy for work, the mastery over self, the deliverance from fear, all spiritual results and graces, are much advanced by prayer.
