To pray is not to use special language; it is the sound of a cry or a laugh rising from ordinary days. Formal or official words can often be lifeless. To pray we need to return like children to an elemental language of soul, to something close to song, to chant, to playground singing.
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.
