The surfaces of the world are aesthetically uneven. You come around a bend in the road and the world suddenly falls open. When we come upon beautiful things . . . they act like small tears in the surface of the world that pull us through to some vaster space.
In every ministry, one is giving something to someone else; in shared silence, one is giving oneself. Sharing interior silence is the giving of one's inmost being to another. When one does this in a group, everyone shares everybody else's level or degree of interior silence. Thus, everyone in the group tends to move to a deeper place than when alone and relying on one's own limited experience.
This is especially the case when silence is penetrated by the gift of interior silence. Then silence is an encounter with the divine presence within. One rests in the conviction of faith and in peace that transcends joy and sorrow. It brings one in face-to-face contact with God, so to speak, a being-to-being exchange.
