Often there's no need to tear off an arm to remove a splinter. — Frank Herbert

The body of Muad'dib is a dry shell like that abandoned by an insect. He mastered the inner world while holding the outer in contempt, and this led to catastrophe. He mastered the outer world while excluding the inner world, and this delivered his decendants to the demons. The Golden Elixer will vanish from Dune, yet Muad'dib's seed goes on, and his water moves our universe.
