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.
Those who neglect silence bring only a distracted heart and a preoccupied mind to their prayer and, instead of deriving new strength from it, they only offer God a heart full of trifles. Intimate conversation with God is easily stifled if you do not first put an end to exterior chatter; yet, if you love silence and keep it well, your heart will be a temple where God will dwell and become known to you there.
