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.
The person who sits is more ready to bring forth clear things than someone who walks or stands. Sitting means peace. Thus we sit, which is bowing in humility among all creatures. Then the individual comes to a quiet peace reaching this peace in light. The light is given in the silence wherein one sits and dwells.
