My writing is like a ten gallon spring. It can issue from the ground anywhere at all. On smooth ground it rushes swiftly on and covers a thouasand li in a single day without difficulty. When it twists and turns among mountains and rocks, it fits its form to things it meets: unknowable. What can be known is, it always goes where it must go, always stops where it cannot help stopping -- nothing else. More than that, even I cannot know.
