On the surface, silence was simple: we didn't speak unless it was necessary. But what was the point of silence? The point was, we learned, not mere silence, not silence to preserve some sort of order, but something much greater. In silence the idea was to recollect ourselves, to place ourselves more squarely in the presence of God than we would if people were talking to us all the time. We could pray, we could meditate, we could contemplate.
In the attitude of silence the soul finds the path in a clearer light, and what is elusive and deceptive resolves itself into crystal clearness. Our life long and arduous quest after Truth and soul requires inward restfulness to attain its full height.
