I concur. I have spent a lot of time on ten day silent meditation courses. These courses are non-sectarian, but there is a strong Theravada buddhism influence. I only say that to emphasize that my initial experience sitting in silence was in no way framed around Jesus. Jesus met me there in the silence, he showed me the moment I accepted Him when I was young, He showed me how I turned from him and chose sin, and He showed me that he was there watching and heartbroken at my ignorance and folly. I realized then how broken I was, what a fucking asshole I had been to the one who loves me the most. I began to understand repentance that day, I had been stumbling through the dark into the darkness while all I ever needed to do was turn around and walk toward the Light. Yeah, silence is powerful. It's worth spending time there.
