“I was studying a river recently (the Pigeon Forge River in Tennessee to be precise) and realized for the very first time that the beautiful sounds the river was making were the result of obstructions (mostly rocks but occasionally logs) in the river’s flow. Thus, no obstructions, no beautiful music. I then began to wonder if it is possible for you and I to make beautiful music without our own obstructions (problems, setbacks, disappointments and tragedies). Somehow, I don’t think so.”
