A person must learn to be alone in solitude, to listen in one's heart to the wordless speech of the Spirit, and to discover the truth bout oneself and God. Then their word to others will be a word of power, because it is a word of silence.
Music is sound AND silence. It is the spaces BETWEEN the notes that create rhythm, melody, and meaning, and the greater the composer -- and the perfornance -- the better the quality of the silence. Legendary pianist Artur Schnabel said that it wasn't the notes but the silences between them he played better than other people. A few seconds more or less at crucial moments in the performance of a piece may mean the difference between a mundane and a transcendent experience.
