Not knowing what you said, you said it. — Frank Herbert

The one-eyed view of our universe says you must not look far afield for problems. Such problems may never arrive. Instead, tend to the wolf within your fences. The packs ranging outside may not even exist.

One of us had to accept the agony, and he was always the stronger.

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.
