Open, attentive listening can be a form of contemplative prayer. It can be that widest, most open form of being present and attentive, in trust that God is present with us, in expectancy that the Spirit will move in the hearts of those present and that we may be changed inwardly for the good or guided to be part of the upwelling of Life in a particular situation.
As long as the soul is not still, there can be no vision. But when stillness has brought us into the presence of God, then another sort of silence, much more absolute, intervenes: the silence of a soul that is not only still and recollected, but which is overawed in an act of worship by God's presence.
