To call these things sacred is to say that they have a value beyond their usefulness for human ends, that they themselves become the standard by which our acts, our economics, our laws, and our purposes must be judged. No one has the right to appropriate them or profit from them at the expense of others. Any government that fails to protect them forfeits its legitimacy.
All people, all living things, are part of the earth life, and so are sacred. No one of us stands higher or lower than any other. Only justice can assure balance: only ecological balance can sustain freedom. Only in freedom can that fifth sacred thing we call spirit flourish in its full diversity.
Since noise is increasing in all directions, the psychology of silence has taken on a special meaning. We are already so adapted to an abundance of screeching sound that we are surprised when stillness suddenly envelops us. Not that this happens very often. We begin to see that the whole question of our relation to the world, both positive and negative, centers in something like silence. So our service to the world might be simply to keep a place where there is no noise, where people can be silent together.
