The discipline of silence doesn't mean just taking a short vacation from the spoken word. It also means giving complete relaxation to the muscles, the tissues, the tongue itself. A modern writer once said: "Knowledge has never been known to enter the head via an open mouth." It is when you become completely silent that you are able to absorb knowledge. God speaks in silence. The discipline of silence is essential on the path.
And now above and beyond the birds' song, Andy hears a more distant singing, whether of voices or instruments, sounds or words, he cannot tell. It is at first faint, and then stronger, filling the sky and touching the ground, and the birds answer it. He understands presently that he is hearing the light; he is hearing the sun, which now has risen, though from the valley it is not yet visible. The light's music resounds and shines in the air and over the countryside, drawing everything into the infinite, sensed but mysterious pattern of its harmony. From every tree and leaf, grass blade, stone, bird, and beast, it is answered and again answers. The creatures sing back their names. But more than their names. They sing their being. The world sings. The sky sings back. It is one song, the song of the many members of one love, the whole song sung and to be sung, resounding, in each of its moments. And it is light.
