Throughout various cultures and political systems of the world, the well has served as a universal symbol for that which sustains life and provides a constant, inexhaustible source of nourishment for mankind. For the life-force, in other words.
Like the well, human nature is the same around the world. The passage of time cannot add to its essential dimensions, nor take anything away. Still, just as a well can be deepened to produce clearer, cleaner water, so can we enrich our essential natures by delving deeply into our lives, and our essential natures.
