One can see the landscape as blocking the path of the water so that it has to turn another way, but again the water just falls in the way that water has to, and the landscape resists its path, in the way it has to. The result of the amorphous water and the form of the landscape is a river.
The conflict between the two nagating powers creates the river. One wthout the other does not a river make. The river runs due to the nagation of the water by the bank. The river moves, or changes courses, by the negation of the bank by the water.
