When we are born, a cry can let the world know that we are healthy and OK. When we first begin to talk, we learn to express our needs and understand the needs of others. As we grow older, we learn that the sound of a siren denotes danger, that certain notes swelling together create the sound of a favourite song which lifts our spirits, or that a warm familiar voice on the other end of the phone means our best friend has our back.
Our ears give us grounding and clues: they are our maps of the world, guiding us towards truth, keeping us from harm, giving us a constant stream of sensory information.
