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.
We become aware of the sacred because it manifests itself, shows itself, as something wholly different from the profane . . . something sacred shows itself to us . . . something of a wholly different order, a reality that does not belong to our world, in objects that are an integral part of our natural "profane" world.
