山川

故上悖日月之明，下爍山川之精，中墮四時之施，惴耎之蟲，肖翹之物，莫不失其性。

It is just as if, above, the brightness of the sun and moon were darkened; as if, beneath, the productive vigour of the hills and streams were dried up; and as if, between, the operation of the four seasons were brought to an end: in which case there would not be a single weak and wriggling insect, nor any plant that grows up, which would not lose its proper nature.
