Silence purifies. Those who are dedicated to silence must persevere in our over-busy world zones of purified air. We must struggle against the asphyxiation, which threatens the cities of our consumer society. We live in a world mentally polluted by verbal intoxication. If dedication to silence did not exist, it would be necessary to invent it.
The way to do is to be!
Without going outside,
you may know the whole world.
Without looking through the window,
you may see the ways of heaven.
The farther you go, the less you know.
Thus the sage knows without traveling ...
sees without looking ...
works without doing.
