Doing work which has to be done over and over again helps us recognize the natural cycles of growth and decay, of birth and death, and thus become aware of the dynamic order of the universe. "Ordinary" work, as the root meaning of the term indicates, is work that is in harmony with the order we perceive in the natural environment.
With the word creative we stand under a mystery. And from time to time that mystery, as if it were a sun, sends down upon one head or another, a sudden shaft of light—by grace, one feels, rather than deserving, for it always is something given, free, unsought, unexpected. It is useless, possibly even profane, to ask for an explanation.
