The effort of bodily prayer can help those not yet granted real prayer of the heart. I am referring to the stretching out of the hands, the beating on the chest, the sincere raising of the eyes heavenward, deep sighs and constant prostrations. But this is not always feasible when other people are present, and this is when the demons particularly like to launch an attack and, because we have not yet the strength of mind to stand up against them and because the hidden power of prayer is not yet within us, we succumb. So go somewhere apart, if you can, hide for a while in some secret place. If you can, lift up the eyes of your soul, but if not, the eyes of your body. Stand still with your arms in the shape of the cross so that with this sign you may shame and conquer your Amalek (Exod 17:11). Cry out to God, Who has the strength to save you. Do not bother with elegant and clever words. Just speak humbly, beginning with, “Have mercy on me, for I am weak” (Ps. 6:3). And then you will come to experience the power of the Most High and with help from heaven you will drive off your invisible foes. The man who gets into the habit of waging war in this way will soon put his enemies to flight solely by means of spiritual resources, for this is the reward God likes to bestow on those who put up a good struggle, and rightly so.
