This wave phenomenon is happening on ever so many scales — the fast wave of light, the slower waves of sound — and there are all sorts of other wave processes, such as the beat of the heart; the rhythm of breath, waking, sleeping; the movement of human life from birth to maturity to death. And the slower the wave goes, the more difficult it is to see that the crest and trough are inseparable, and this is how we become persuaded in the game of hide-and-seek. So we see the trough go down, down, down and think it keeps going forever — that it will never rise back up again into a crest. We forget that trough implies crest, and crest implies trough. There is no such thing as pure sound — sound is sound/silence. Light is light/darkness. Light is pulsation — between every light pulse there is the dark pulse.
