Silence is difficult and arduous; it is not to be played with. It isn't something that you can experience by reading a book, or by listening to a talk, or by sitting together, or by retiring into a wood or a monastery. I am afraid none of these things will bring about this silence. This silence demands intense psychological work. You have to be burningly aware - aware of your speech, aware of your snobbishness, aware of your fears, your anxieties, your sense of guilt. And when you die to all that, then out of that dying comes the beauty of silence.
