Silence is a necessity for a contemplative soul, and there can be no prayer without it. To each of us is given the obligation to make our cloister and our soul a house of prayer, the home of the Blessed Trinity, a sanctuary of God, where we may pass our life listening to him and learning all from him. Let us be watchful over interior silence, especially. We are all aware how easily a slight contradiction may call up a multitude of persons and things to occupy our minds. These are “intruders” we are letting into the sanctuary, causing us to lose sight of the Divine Guest therein and to lose precious time with things that in no way concern his glory. We must bring back our souls to silence and solitude as soon as such thoughts arise to disturb the peace of our interior sanctuary.
