When you and the silence become friends, it will speak to you as loudly as anything you could ever hear from the outer world. Soon you will not be able to ignore its voice, which after all is the voice of your own spirit calling to you.
Just as God speaks to us through the words of scripture, so God speaks to us through the elements of creation. The cosmos is like a living sacred text that we can learn to read and interpret. Just as we prayerfully ponder the words of the Bible in Christian practice, and as other traditions study their sacred texts, so we are invited to listen to the life of creation as an ongoing, living utterance of God.
