Buddha's
teaching has two faces. One is practical and the other is philosophical.
The Four Noble truths and the Eightfold Holy Path are practical teaching. The
teaching of interdependence and transiency are the philosophical side. The
practical side of the teaching, or the teaching based on value, is for human beings. But the teaching that everything
changes and is independent is not just for human beings, it is the teaching for
everything.
