Many have marked the speed with which Muad'Dib learned the necessities of Arrakis. The Bene Gesserit, of course, know the basis of this speed. For the others, we can say that Muad'Dib learned rapidly because his first training was in how to learn. And the first lesson of all was the basic trust that he could learn. It is shocking to find how many people do not believe they can learn, and how many more believe learning to be difficult. Muad'Dib knew that every experience carries its lesson.

To come under siege was the inevitable fate of power.

When you think to take determination of your fate into your own hands, that is the moment you can be crushed. Be cautious.

To be a god can ultimately become boring and degrading. There'd be reason enough for the invention of free will! A god might wish to escape into sleep and be alive only in the unconscious projections of his dream-creatures.

Growth is limited by that necessity which is present in the least amount.

Guilt starts as a feeling of failure.

That path leads ever down into stagnation.
