In this world, everything has name and form. Within time and space, everything is changing. Among the ten thousand different things, there is not one that is not subject to the law of change. Everybody gathered here today has eaten and then come here. During that time your body has already changed.
Mountain is emptiness, water is also emptiness.
Beyond time and space means no name and no form. At this point we return to the substance of the whole universe, to our original substance. In true emptiness there are no opposites, there is only the absolute. This is the world of Nirvana. Mountain is mountain, water is water.
