The highest good is like water, which benefits all things without dispute. ------- Tao Te Ching
Water is the source of life, growth is the basis of all living things.In this case, take water as morality, and people live near the water. Let the whole physical environment full of aura. From the senses to the mind, the realm of "harmony between man and nature" is reached.Close to Tao, and close to people,it is walkable, appreciable, available for visit and habitable.
