The Buddha described the world as an unending flux of becoming. All is changeable, continuous transformation, ceaseless mutation, and a moving stream. Everything exists from moment to moment. Everything is a recurring rotation of coming into being and then passing out of existence. Everything is moving from birth to death. Life is a continuous movement of change towards death. The matter or material forms in which life does or does not express itself, are also a continuous movement or change towards decay. This teaching of the impermanent nature on earth partakes of the character of absolute reality. That there will be no death of what is born is impossible. Whatever is subject to origination is subject also to destruction. Change is the very constituent of reality.
