  What seems to us, through perception, to be generation of new entities or destruction of old ones is not that at all. Rather, objects that appear to us to be born, to grow, and to die, are merely arrangements and re-arrangements of more metaphysically basic ingredients. The mechanism for the apparent coming-to-be is mixing and separating out from the mixture produced by the vortex motion of the ingredients. Through that mechanism, the real things, the ingredients, can retain their character throughout. When an arrangement breaks apart (or “passes away”) the ingredients are dissociated from one another (through separation) and can be re-mixed to form (or “become”) different arrangements, i.e., other perceptible objects.
