A legend told by the Venerable Bede says that the poet Caedmon was once completely mute. It was a custom in his village to spend evenings taking turns reciting poetry. On these occasions, Caedmon, unable to speak, would steal away to nearby hills to escape. One evening while walking alone, an angel appeared and urged him to sing. Miraculously, he began to sing and went on the become a famous poet.
This is called the Temple of Silence, the Place of Power; for when we reach the place of silence in mind, we have reached the place of power -- the place where all is one, the one power -- God... Only as we turn from the without to the silence of the within can we hope to make conscious union with God... God does not speak so much in the fire, the earthquake, or the great wind, as in the still, small voice -- the still, small voice deep in our own souls.
