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.
Meditating in silence is a little like donning black robes. You turn off your internal music and distracting narrative, and stop worrying about whether you fit in. You realize that stillness can offer another way of learning and communication. Rather than marching to a different drummer, you walk along quietly at your own pace, not leading, not following, just trying to experience the entire parade.
