From "Manual of Muad'Dib" by the Princess Irulan

He's overconfident , Paul thought. There's a natural advantage I can accept .
"Get the Emperor's blade," Paul said, and watched as his command was obeyed. "Put it on the floor there." He indicated a place with his foot. "Clear the Imperial rabble back against the wall and let the Harkonnen stand clear."
A flurry of robes, scraping of feet, low-voiced commands and protests accompanied obedience to Paul's command. The Guildsmen remained standing near the communications equipment. They frowned at Paul in obvious indecision.
They're accustomed to seeing the future , Paul thought. In this place and time they're blind . . . even as I am . And he sampled the time-winds, sensing the turmoil, the storm nexus that now focused on this moment place. Even the faint gaps were closed now. Here was the unborn jihad, he knew. Here was the race consciousness that he had known once as his own terrible purpose. Here was reason enough for a Kwisatz Haderach or a Lisan al-Gaib or even the halting schemes of the Bene Gesserit. The race of humans had felt its own dormancy, sensed itself grown stale and knew now only the need to experience turmoil in which the genes would mingle and the strong new mixtures survive. All humans were alive as an unconscious single organism in this moment, experiencing a kind of sexual heat that could override any barrier.
And Paul saw how futile were any efforts of his to change any smallest bit of this. He had thought to oppose the jihad within himself, but the jihad would be. His legions would rage out from Arrakis even without him. They needed only the legend he already had become. He had shown them the way, given them mastery even over the Guild which must have the spice to exist.
A sense of failure pervaded him, and he saw through it that Feyd-Rautha Harkonnen had slipped out of the torn uniform, stripped down to a fighting girdle with a mail core.
This is the climax , Paul thought. From here, the future will open, the clouds part onto a kind of glory. And if I die here, they'll say I sacrificed myself that my spirit might lead them. And if I live, they'll say nothing can oppose Muad'Dib .
"Is the Atreides ready?" Feyd-Rautha called, using the words of the ancient kanly ritual.
Paul chose to answer him in the Fremen way: "May thy knife chip and shatter!" He pointed to the Emperor's blade on the floor, indicating that Feyd-Rautha should advance and take it.
Keeping his attention on Paul, Feyd-Rautha picked up the knife, balancing it a moment in his hand to get the feel of it. Excitement kindled in him. This was a fight he had dreamed about—man against man, skill against skill with no shields intervening. He could see a way to power opening before him because the Emperor surely would reward whoever killed this troublesome duke. The reward might even be that haughty daughter and a share of the throne. And this yokel duke, this back-world adventurer could not possibly be a match for a Harkonnen trained in every device and every treachery by a thousand arena combats. And the yokel had no way of knowing he faced more weapons than a knife here.
Let us see if you're proof against poison! Feyd-Rautha thought. He saluted Paul with the Emperor's blade, said: "Meet your death, fool."
"Shall we fight, cousin?" Paul asked. And he cat-footed forward, eyes on the waiting blade, his body crouched low with his own milk-white crysknife pointing out as though an extension of his arm.
They circled each other, bare feet grating on the floor, watching with eyes intent for the slightest opening.
"How beautifully you dance," Feyd-Rautha said.
He's a talker , Paul thought. There's another weakness. He grows uneasy in the face of silence .
"Have you been shriven?" Feyd-Rautha asked.
Still, Paul circled in silence.
And the old Reverend Mother, watching the fight from the press of the Emperor's suite, felt herself trembling. The Atreides youth had called the Harkonnen cousin. It could only mean he knew the ancestry they shared, easy to understand because he was the Kwisatz Haderach. But the words forced her to focus on the only thing that mattered to her here.
This could be a major catastrophe for the Bene Gesserit breeding scheme.
She had seen something of what Paul had seen here, that Feyd-Rautha might kill but not be victorious. Another thought, though, almost overwhelmed her. Two end products of this long and costly program faced each other in a fight to the death that might easily claim both of them. If both died here that would leave only Feyd-Rautha's bastard daughter, still a baby, an unknown, an unmeasured factor, and Alia, the abomination.
"Perhaps you have only pagan rites here," Feyd-Rautha said. "Would you like the Emperor's Truthsayer to prepare your spirit for its journey?"
Paul smiled, circling to the right, alert, his black thoughts suppressed by the needs of the moment.
Feyd-Rautha leaped, feinting with right hand, but with the knife shifted in a blur to his left hand.
Paul dodged easily, noting the shield-conditioned hesitation in Feyd-Rautha's thrust. Still, it was not as great a shield conditioning as some Paul had seen, and he sensed that Feyd-Rautha had fought before against unshielded foes.
"Does an Atreides run or stand and fight?" Feyd-Rautha asked.
Paul resumed his silent circling. Idaho 's words came back to him, the words of training from the long-ago practice floor on Caladan: "Use the first moments in study. You may miss many an opportunity for quick victory this way, but the moments of study are insurance of success. Take your time and be sure ."
"Perhaps you think this dance prolongs your life a few moments," Feyd-Rautha said. "Well and good." He stopped the circling, straightened.
Paul had seen enough for a first approximation. Feyd-Rautha led to the left side, presenting the right hip as though the mailed fighting girdle could protect his entire side. It was the action of a man trained to the shield and with a knife in both hands.
