Cries for help are frequently inaudible.

— Tom Robbins

It is only with the heart that one can see, hear and feel clearly. Think of an image, music or movie that moves you. Things that we truly love to touch our heart before our head analyzes them away. Once we think we understand them, they disappear... It is because simple things in life are invisible, inaudible and insensible to an analytical mind and an undiscerning heart. Let your heart hear the music -- be moved by images, people and places... for that makes you more alive than others.

— Val Uchendu

Love is inaudible—until you hear it. And once you do, you’ll never forget the sound of her voice.


— Dark Jar Tin Zoo

Through you, we learn to be invisible, through you inaudible; and hence we can hold the enemy's fate in our hands.

— Sun Tzu
