Was it not the blue of the sky that taught us what blue was.
Was it not the changing light, that taught us the movement of time.
The blue deepens and the blinking lights we have created ourselves have never, and will never catch up with the sky as it smothers us into darkness, in a short, swift hour. Only real light will reach, the deepest part of the earth, all at the same time, unfailingly, all at once. Other than the dawn, only the heart breaks into light.
