The burning! The burning!

He thought he could feel skin curling black on that agonized hand, the flesh crisping and dropping away until only charred bones remained.

It stopped!

As though a switch had been turned off, the pain stopped.

Paul felt his right arm trembling, felt sweat bathing his body.

"Enough," the old woman muttered. "Kull wahad! No woman child ever withstood that much. I must've wanted you to fail." She leaned back, withdrawing the gom jabbar from the side of his neck. "Take your hand from the box, young human, and look at it."

He fought down an aching shiver, stared at the lightless void where his hand seemed to remain of its own volition. Memory of pain inhibited every movement. Reason told him he would withdraw a blackened stump from that box.

"Do it!" she snapped.

He jerked his hand from the box, stared at it astonished. Not a mark. No sign of agony on the flesh. He held up the hand, turned it, flexed the fingers.

"Pain by nerve induction," she said. "Can't go around maiming potential humans. There're those who'd give a pretty for the secret of this box, though." She slipped it into the folds of her gown.

"But the pain—" he said.

"Pain," she sniffed. "A human can override any nerve in the body."

Paul felt his left hand aching, uncurled the clenched fingers, looked at four bloody marks where fingernails had bitten his palm. He dropped the hand to his side, looked at the old woman. "You did that to my mother once?"

"Ever sift sand through a screen?" she asked.

The tangential slash of her question shocked his mind into a higher awareness: Sand through a screen , he nodded.

"We Bene Gesserit sift people to find the humans."

He lifted his right hand, willing the memory of the pain. "And that's all there is to it—pain?"

"I observed you in pain, lad. Pain's merely the axis of the test. Your mother's told you about our ways of observing. I see the signs of her teaching in you. Our test is crisis and observation."

He heard the confirmation in her voice, said: "It's truth!"

She stared at him. He senses truth! Could he be the one? Could he truly be the one? She extinguished the excitement, reminding herself: "Hope clouds observation ."

"You know when people believe what they say," she said.

"I know it."

The harmonics of ability confirmed by repeated test were in his voice. She heard them, said: "Perhaps you are the Kwisatz Haderach. Sit down, little brother, here at my feet."

"I prefer to stand."

"Your mother sat at my feet once."

"I'm not my mother."

"You hate us a little, eh?" She looked toward the door, called out: "Jessica!"

The door flew open and Jessica stood there staring hard-eyed into the room. Hardness melted from her as she saw Paul. She managed a faint smile.

"Jessica, have you ever stopped hating me?" the old woman asked.

"I both love and hate you," Jessica said. "The hate—that's from pains I must never forget. The love—that's... "

"Just the basic fact," the old woman said, but her voice was gentle. "You may come in now, but remain silent. Close that door and mind it that no one interrupts us."

Jessica stepped into the room, closed the door and stood with her back to it. My son lives , she thought. My son lives and is... human. I knew he was... but... he lives. Now, I can go on living . The door felt hard and real against her back. Everything in the room was immediate and pressing against her senses.

My son lives .

Paul looked at his mother. She told the truth . He wanted to get away alone and think this experience through, but knew he could not leave until he was dismissed. The old woman had gained a power over him. They spoke truth . His mother had undergone this test. There must be terrible purpose in it... the pain and fear had been terrible. He understood terrible purposes. They drove against all odds. They were their own necessity. Paul felt that he had been infected with terrible purpose. He did not know yet what the terrible purpose was.

"Some day, lad," the old woman said, "you, too, may have to stand outside a door like that. It takes a measure of doing."

Paul looked down at the hand that had known pain, then up to the Reverend Mother. The sound of her voice had contained a difference then from any other voice in his experience. The words were outlined in brilliance. There was an edge to them. He felt that any question he might ask her would bring an answer that could lift him out of his flesh-world into something greater.

"Why do you test for humans?" he asked.

"To set you free."

"Free?"

"Once men turned their thinking over to machines in the hope that this would set them free. But that only permitted other men with machines to enslave them."

"'Thou shalt not make a machine in the likeness of a man's mind,' " Paul quoted.

"Right out of the Butlerian Jihad and the Orange Catholic Bible," she said. "But what the O.C. Bible should've said is: 'Thou shalt not make a machine to counterfeit a human mind.' Have you studied the Mentat in your service?"

"I've studied with Thufir Hawat."

"The Great Revolt took away a crutch," she said. "It forced human minds to develop. Schools were started to train human talents."

"Bene Gesserit schools?"

She nodded. "We have two chief survivors of those ancient schools: the Bene Gesserit and the Spacing Guild. The Guild, so we think, emphasizes almost pure mathematics. Bene Gesserit performs another function."

"Politics," he said.

"Kull wahad!" the old woman said. She sent a hard glance at Jessica.

"I've not told him. Your Reverence," Jessica said.

The Reverend Mother returned her attention to Paul. "You did that on remarkably few clues," she said. "Politics indeed. The original Bene Gesserit school was directed by those who saw the need of a thread of continuity in human affairs. They saw there could be no such continuity without separating human stock from animal stock—for breeding purposes."

The old woman's words abruptly lost their special sharpness for Paul. He felt an offense against what his mother called his instinct for rightness . It wasn't that Reverend Mother lied to him. She obviously believed what she said. It was something deeper, something tied to his terrible purpose.

He said: "But my mother tells me many Bene Gesserit of the schools don't know their ancestry."

"The genetic lines are always in our records," she said. "Your mother knows that either she's of Bene Gesserit descent or her stock was acceptable in itself."

"Then why couldn't she know who her parents are?"

"Some do... Many don't. We might, for example, have wanted to breed her to a close relative to set up a dominant in some genetic trait. We have many reasons."

Again, Paul felt the offense against rightness. He said: "You take a lot on yourselves."

The Reverend Mother stared at him, wondering: Did I hear criticism in his voice? "We carry a heavy burden," she said.

Paul felt himself coming more and more out of the shock of the test. He leveled a measuring stare at her, said: "You say maybe I'm the... Kwisatz Haderach. What's that, a human gom jabbar?"

"Paul," Jessica said. "You mustn't take that tone with—"

"I'll handle this, Jessica," the old woman said. "Now, lad, do you know about the Truthsayer drug?"

"You take it to improve your ability to detect falsehood," he said. "My mother's told me."

"Have you ever seen truthtrance?"

He shook his head. "No."

"The drug's dangerous," she said, "but it gives insight. When a Truthsayer's gifted by the drug, she can look many places in her memory—in her body's memory. We look down so many avenues of the past... but only feminine avenues." Her voice took on a note of sadness. "Yet, there's a place where no Truthsayer can see. We are repelled by it, terrorized. It is said a man will come one day and find in the gift of the drug his inward eye. He will look where we cannot—into both feminine and masculine pasts."
