When you and the silence become friends, it will speak to you as loudly as anything you could ever hear from the outer world. Soon you will not be able to ignore its voice, which after all is the voice of your own spirit calling to you.
You can listen to silence, Reuven. I've begun to realize that you can listen to silence and listen to it. It has a quality and a dimension all its own. It talks to me sometimes. I feel myself alive in it. It talks. I can hear it.
