It is easy in the world to live after the world's opinion; it is easy in solitude to live after our own; but great are those who in the midst of the crowd keep with perfect sweetness the independence of solitude.
~ Ralph Waldo Emerson
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.
