You can listen to silence, Reuven. I've begun to realize that you can listen to silence and listen to it. It has a quality and a dimension all its own. It talks to me sometimes. I feel myself alive in it. It talks. I can hear it.
Prayer may take the shape of sacrifice, supplication, adoration or meditation; it may even appear in simple daily acts of kindness; but it is always the outer visible sign of an inward communion with the Divine.
