He who has found his soul's life in God is happy -- not, in truth, with perfect happiness: that is not granted to men in this world, but a foretaste thereof --he has a secret joy which is beyond the reach of temptation, unrest, and sorrow; a quiet confidence and steadfastness which abide even while the waves and storms of life sweep over him... When the soul has sincerely given itself up to God, He fills it with His own peace, a peace which makes all earthly things indifferent -- as before His Presence, absorbing the heart. It is our strength, our comfort, our guide, the deeper and more confirmed it becomes, the greater our spiritual perfection; so that in truth to obtain and preserve this peace is the real secret of the interior life.
