Next I saw the most lucid air, in which I heard in a marvelous way many kinds of musicians praising the joys of the heavenly citizens. ... And their sound was like the voice of a multitude, making music in harmony.
If the heart wanders or is distracted, bring it back to the point quite gently... And even if you did nothing during the whole of your hour but bring your heart back, though it went away every time you brought it back, your hour would be very well employed.
~ St. Francis de Sales in INTRODUCTION TO THE DEVOUT LIFE
Make friends with the angels, who though invisible are always with you. Invoke them often and trust in their help and assistance in all your temporal and spiritual affairs.
