Our imagination, which is hardly still a minute, makes our task harder and then of course there is the devil who never tires of trying to distract us and keep us from praying. To what ends does not the evil one go against us while we are engaged in saying our Rosary against him.
Being human, we easily become tired and slipshod----but the devil makes these difficulties worse when we are saying the Rosary. Before we even begin he makes us feel bored, distracted or exhausted----and when we have started praying he oppresses us from all sides. And when, after much difficulty and many distractions, we have finished, he whispers to us: "What you have just said is worthless. It's useless for you to say the Rosary. You had better get on with other things. It's only a waste of time to pray without paying attention to what you're saying; half an hour's meditation or some spiritual reading would be much better. Tomorrow when you're not feeling so sluggish you'll pray better; don't finish your Rosary until tomorrow." By tricks of this kind the devil gets us to give up the Rosary altogether or else hardly say it at all, and we keep putting it off or else change to some other devotion.
Dear Rosary Confraternity members, do not listen to the devil, but be of good heart even if your imagination has been bothering you throughout your Rosary, filling your mind with all kinds of distracting thoughts----as long as you really tried hard to get rid of them as soon as they came. Always remember that the best Rosary is the one with the most merit, and there is more merit in praying when it is hard than when it is easy. Prayer is all the harder when it is (naturally speaking) distasteful to the soul and is filled with those annoying little ants and flies running about in your imagination, against your will, and scarcely allowing you the time to enjoy a little peace and appreciate the beauty of what you are saying.
Even if you have to fight distractions all through your whole Rosary be sure to fight well, arms in hand: that is to say, do not stop saying your Rosary even if it is hard to say and you have absolutely no sensible devotion. It is a terrible battle, I know, but one that is profitable to the faithful soul. If you put down your arms, that is, if you give up the Rosary, you will be admitting defeat and then, having won, the devil will leave you alone.
But at the Day of Judgment he will taunt you because of your faithlessness and lack of courage. "He that is faithful in that which is least, is faithful also in that which is greater" (St. Luke 16: 10). He who fights even the smallest distractions faithfully when he says even the very smallest prayer he will also be faithful in great things. We can be absolutely certain of this because the Holy Spirit has told us so.
So all of you, servants and handmaids of Our Lord Jesus Christ and the Blessed Virgin Mary, who have made up your minds to say the Rosary every day, be of good heart. Do not let the flies (it is thus that I call the distractions that make war on you during prayer) make you cowardly abandon the company of Jesus and Mary, in whose holy presence you always are when saying the Rosary. In what follows I shall give you suggestions for getting rid of distractions.
