"Water is patient; it can stagnate and let itself be coated with scum if need be. It is as gentle as the morning's dew. It is non-confrontational, even respectful, in circumventing the rocks in a stream. It makes room for everything that enters its pools. It accommodates by assuming the shape of any vessel it is poured into. And it is humble, seeking always the lowest level. Yet along with - or rather because of these adaptive, yielding properties, it is ultimately irresistible; it carves canyons out of stone."
