For sheer adventure, exploring the inner space of the human spirit has to equal the exploration of outer space. Inner space holds a realm of existence not readily apparent when we are in the grip of the strident external world. A powerful launching vehicle for the discovery of the realm within is silence. It is in the vessel of silence that inner transformation can occur.
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.
