Well: the power of roiling or rising in successive, patterned swells, like a series of exhaled breaths without inhalation. The term is used to denote a source of water that rises from the power of welling energy but, logically enough, not from the earth, as a well is a hole in the earth and thus not the earth at all. It is a window that gives not entrance or exit but itself. Often, welling is a latent energy, known as a swell (or swelling), which can be brought to life by a change in state or the addition of energy. An arm lanced with a knife, for instance, transforms the swelling energy given to it by the body’s heart and wells with blood.
