There is no other fact but silence which has not been invited, induced, sought after, but which is the natural outcome of observation and of understanding oneself and the world about one. In this there has been no motive which has brought silence. If there is any shadow or suspicion of a motive, then that silence is directed and deliberate, so it is not silence at all. If you can honestly say that that silence is free, then what actually takes place in that silence is our only concern. What is the quality and the texture of that silence? Is it superficial, passing, measurable? Are you aware of it after it is over, or during the silence? If you are aware that you have been silent, then it is only a memory, and therefore dead. If you are aware of the silence while it is happening, then is it silence?
