Remember that your soul is a temple of the living God. The kingdom of God is within you. Night and day let your aim be to remain in simplicity and gentleness, calmness and serenity, and in freedom from created things, so that you will find your joy in the Lord Jesus. Love silence and solitude, even when in the midst of a crowd or when caught up in your work. Physical solitude is a good thing, provided that it is backed up by prayer and a holy life, but far better than this is solitude of the heart, which is the interior desert in which your spirit can become totally immersed in God, and can hear and savor the words of eternal life. With great purity of intention, aim in everything to do what pleases God. Always remain faithful to God and genuinely accept whatever he wishes.
– St. Paul of the Cross
