To talk about silence seems a paradox, as the sound of one's words apparently shatters the silence. Most of us have learned that silence is the polar opposite of sound and that sound can break it; but understanding this differently, we find that silence is to the ear what space is to the eye.
When an object is perceived in space, we do not think that space has been broken. In the same way when sound appears in silence, silence has not been broken. Silence contains sound in the same way that space contains objects. When you notice this, each sound is surrounded by silence.
