Several times during the day, but especially in the morning and evening, ask yourself for a moment if you have your soul in your hands or if some passion or fit of anxiety has robbed you of it. Consider whether you have command of your heart or whether it has slipped into some disorderly passion of love, hatred, envy, covetousness, fear, uneasiness or joy. If you have gone astray, quietly bring your soul back to the presence of God, subjecting all your affections and desires to the obedience and direction of His Divine Will. Just as men who are afraid of losing a precious pearl hold it firmly in their hands, so we must keep a close watch on the precious pearl of our soul.
Saint Francis de Sales
