"I've heard you call that political necessity," Odrade said.

Taraza spoke with tight control while returning her attention to the display in front of her. "If we become institutionalized in our judgments, that's a sure way to extinguish the Bene Gesserit."

"You will not find petty decisions in my bio," Odrade said.

"I look for sources of weakness, for flaws."

"You won't find those, either."

Taraza concealed a smile. She recognized this egocentric remark: Odrade's way of needling the Mother Superior. Odrade was very good at seeming to be impatient while actually suspending herself in a timeless flow of patience.

When Taraza did not rise to the bait, Odrade resumed her calm waiting - easy breaths, the mind steady. Patience came without thinking of it. The Sisterhood had taught her long ago how to divide past and present into simultaneous flowings. While observing her immediate surroundings, she could pick up bits and pieces of her past and live through them as though they moved across a screen superimposed over the present.

Memory work, Odrade thought. Necessary things to haul out and lay to rest. Removing the barriers. When all else palled, there was still her tangled childhood.

There had been a time when Odrade lived as most children lived: in a house with a man and woman who, if not her parents, certainly acted in loco parentis. All of the other children she knew then lived in similar situations. They had papas and mamas. Sometimes only papa worked away from home. Sometimes only mama went out to her labors. In Odrade's case, the woman remained at home and no creche nurse guarded the child in the working hours. Much later, Odrade learned that her birth-mother had given a large sum of money to provide this for the infant female hidden in plain sight that way.

"She hid you with us because she loved you," the woman explained when Odrade was old enough to understand. "That is why you must never reveal that we are not your real parents."

Love had nothing to do with it, Odrade learned later. Reverend Mothers did not act from such mundane motives. And Odrade's birth-mother had been a Bene Gesserit Sister.

All of this was revealed to Odrade according to the original plan. Her name: Odrade. Darwi was what she had always been called when the caller was not being endearing or angry. Young friends naturally shortened it to Dar.

Everything, however, did not go according to the original plan. Odrade recalled a narrow bed in a room brightened by paintings of animals and fantasy landscapes on the pastel blue walls. White curtains fluttered at the window in the soft breezes of spring and summer. Odrade remembered jumping on the narrow bed - a marvelously happy game: up, down, up, down. Much laughter. Arms caught her in mid leap and hugged her close. They were a man's arms: a round face with a small mustache that tickled her into giggles. The bed thumped the wall when she jumped and the wall revealed indentations from this movement.

Odrade played over this memory now, reluctant to discard it into the well of rationality. Marks on a wall. Marks of laughter and joy. How small they were to represent so much.

Odd how she had been thinking more and more about papa recently. All of the memories were not happy. There had been times when he had been sad-angry, warning mama not to become "too involved." He had a face that reflected many frustrations. His voice barked when he was in his angry mood. Mama moved softly then, her eyes full of worry. Odrade sensed the worry and the fear and resented the man. The woman knew best how to deal with him. She kissed the nape of his neck, stroked his cheek and whispered into his ear.

These ancient "natural" emotions had engaged a Bene Gesserit analyst-proctor in much work with Odrade before they were exorcised. But even now there was residual detritus to pick up and discard. Even now, Odrade knew that all of it was not gone.

Seeing the way Taraza studied the biographical record with such care, Odrade wondered if that was the flaw the Mother Superior saw.

Surely they know by now that I can deal with the emotions of those early times.

It was all so long ago. Still, she had to admit that the memory of the man and woman lay within her, bonded with such force that it might never be erased completely. Especially mama.

The Reverend Mother in extremis who had borne Odrade had put her in that hiding place on Gammu for reasons Odrade now understood quite well. Odrade harbored no resentments. It had been necessary for the survival of them both. Problems arose from the fact that the foster mother gave Odrade that thing which most mothers give their children, that thing which the Sisterhood so distrusted - love.

When the Reverend Mothers came, the foster mother had not fought the removal of her child. Two Reverend Mothers came with a contingent of male and female proctors. Afterward Odrade was a long time understanding the significance of that wrenching moment. The woman had known in her heart that the day of parting would come. Only a matter of time. Still, as the days became years - almost six standards of years - the woman had dared to hope.

Then the Reverend Mothers came with their burly attendants. They had merely been waiting until it was safe, until they were sure no hunters knew this was a Bene Gesserit-planned Atreides scion.

Odrade saw a great deal of money passed to the foster mother. The woman threw the money on the floor. But no voice was raised in objection. The adults in the scene knew where the power lay.

Calling up those compressed emotions, Odrade could still see the woman take herself to a straight-backed chair beside the window onto the street, there to hug herself and rock back and forth, back and forth. Not a sound from her.

The Reverend Mothers used Voice and their considerable wiles plus the smoke of drugging herbs and their overpowering presence to lure Odrade into their waiting groundcar.

"It will be just for a little while. Your real mother sent us."

Odrade sensed the lies but curiosity compelled. My real mother!

Her last view of the woman who had been her only known female parent was of that figure at the window rocking back and forth, a look of misery on her face, arms wrapped around herself.

Later, when Odrade spoke of returning to the woman, that memory-vision was incorporated into an essential Bene Gesserit lesson.

"Love leads to misery. Love is a very ancient force, which served its purpose in its day but no longer is essential for the survival of the species. Remember that woman's mistake, the pain."

Until well into her teens, Odrade adjusted by daydreaming. She would really return after she was a full Reverend Mother. She would go back and find that loving woman, find her even though she had no names except "mama" and "Sibia." Odrade recalled the laughter of adult friends who had called the woman "Sibia."

Mama Sibia.

The Sisters, however, detected the daydreams and searched out their source. That, too, was incorporated into a lesson.

"Daydreaming is the first awakening of what we call simulflow. It is an essential tool of rational thought. With it you can clear the mind for better thinking."

Simulflow.

Odrade focused on Taraza at the morning room table. Childhood trauma must be placed carefully into a reconstructed memory-place. All of that had been far away on Gammu, the planet that the people of Dan had rebuilt after the Famine Times and the Scattering. The people of Dan - Caladan in those days. Odrade took a firm grip on rational thought, using the stance of the Other Memories that had flooded into her awareness during the spice agony when she had really become a full Reverend Mother.

Simulflow... the filter of consciousness... Other Memories.

What powerful tools the Sisterhood had given her. What dangerous tools. All of those other lives lay there just beyond the curtain of awareness, tools of survival, not a way to satisfy casual curiosity.
