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.
You can visualize God's light each day and send it to someone who needs help. Your divine nature must reach out and touch the divine nature of another. Within you is the light of the world. It must be shared with the world.
