A little lifting up of the heart suffices; a little remembrance of God, an interior act of adoration, even though made on the march and with sword in hand, are prayers which, short though they may be, are nevertheless very pleasing to God, and far from making a soldier lose his courage on the most dangerous occasions, bolster it. Let him then think of God as much as possible so that he will gradually become accustomed to this little but holy exercise; no one will notice it and nothing is easier than to repeat often during the day these little acts of interior adoration.
