That which we call composition and decomposition and construction and destruction of things, all those are due to change, one thing turning into another. There is no such thing as death or real decomposition or destruction. It may be destruction of that particular object, but although that part which appeared in certain form or color has changed, it is not the true elements of the thing which have changed. Therefore birth and death, composing and decomposing form the constant changes in the appearance of things of life.
