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.
All final spiritual reference is to be the silence beyond sound. The word made flesh is the first sound. Beyond that sound is the transcendent unknown, the unknowable. It can be spoken of as the great silence, or as the void, or as the transcendent absolute.
