I haven't read this book, but I really like the idea of silence as a spiritual practice.
I'm also constantly amazed that God says very different things to different people. In any major sporting event, is God really on both sides?
So here's an Evangelical look at when God doesn't talk to you. Spread the word, sometimes silence is golden.
In Buddhist traditions, the whole point is not to fill your head with chatter. Nobody knows better than a Buddhist that the chatter in your head is mostly that, chatter. The still, small voice is not the clarion call to closemindedness that some seem to believe is God.
