Silence is no passive thing. It is a vibrant presence which fills any vacuum in sound and conveys its own living quality. Most of us know the truth of the phrase "the silence that sounds," and the old adage "silence is golden" means more than just that it is safe or wise. It means that it is golden in the sense of being filled with light.
A day filled with noise and voices can be a day of silence, if the noises become for us the echo of the presence of God, if the voices are, for us, messages and solicitations of God.
