Hsuan

That which is deep, dark and mysterious prior to any distinction between order and chaos-before any classification and naming of the features of the world. The chaos of hsuan is the nature of the world before any distinctions have been marked out and named, but as soon as even one distinction has been made, as between yin and yang or between 0 and 1, all that we call laws or principles of mathmatics, physics and biology follow of necessity.
