Since noise is increasing in all directions, the psychology of silence has taken on a special meaning. We are already so adapted to an abundance of screeching sound that we are surprised when stillness suddenly envelops us. Not that this happens very often. We begin to see that the whole question of our relation to the world, both positive and negative, centers in something like silence. So our service to the world might be simply to keep a place where there is no noise, where people can be silent together.
Each person, no matter how old, has an important work to do. This good work not only accomplishes something needed in the world, but completes something in us. The work we do in the world, when it is true vocation, always corresponds in some mysterious way to the work that goes on within us.
