Words move, music moves Only in time; but that which is only living Can only die. Words, after speech, reach Into the silence. Only by the form, the pattern, Can words or music reach The stillness.
The pause - that impressive silence, that eloquent silence, that geometrically progressive silence which often achieves a desired effect where no combination of words, howsoever felicitous, could accomplish it.
When you inquire 'Who am I?' if you are honest, you'll notice that it takes you right back to silence instantly. The brain doesn't have an answer, so all of a sudden there is silence.
