CCC 2729

The habitual difficulty in prayer is distraction. It can affect words and their meaning in vocal prayer; it can concern, more profoundly, him to whom we are praying, in vocal prayer (liturgical or personal), meditation, and contemplative prayer. To set about hunting down distractions would be to fall into their trap, when all that is necessary is to turn back to our heart: for a distraction reveals to us what we are attached to, and this humble awareness before the Lord should awaken our preferential love for him and lead us resolutely to offer him our heart to be purified. Therein lies the battle, the choice of which master to serve.
