There is no effort that we can make to still ourselves. True stillness comes naturally from moments of solitude where we allow our minds to settle. Just as water seeks its own level, the mind will gravitate toward the holy. Muddy water will become clear if allowed to stand undisturbed, and so too will the mind become clear if it is allowed to be still.
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.
