Our son has been traveling in Europe. Although his knowledge of foreign languages is limited, he has found creative ways to communicate without words. It has been awhile since he was a baby, but I remember how various sounds of his cry conveyed different things. Words are not always needed to communicate and understand; but listening is. Those who cannot physically hear may actually be the best listeners, for they have learned to listen with their hearts.
Listen with the ear of your heart. ~ Saint Benedict
Give ear to my words, O LORD; give heed to my sighing. Listen to the sound of my cry, my King and my God, for to you I pray. – Psalm 5:1-2
