“ Then she said a good ruler has to learn his world’s language, that it’s different for every world. And I thought she meant they didn’t speak Galach on Arrakis, but she said that wasn’t it at all. She said she meant the language of the rocks and growing things, the language you don’t hear just with your ears. And I said that’s what Dr. Yueh calls the Mystery of Life.” Hawat chuckled. “How’d that sit with her?” “I think she got mad. She said the mystery of life isn’t a problem to solve, but a reality to experience. So I quoted the First Law of Mentat at her: 'A process cannot be understood by stopping it. Understanding must move with the flow of the process, must join it and flow with it. ”
