This is a passage from Being-In-Dreaming where Esperanza explains to Florinda details about using the ability to feel with the womb in order to enter dreaming.
Esperanza explained, "To reach a point of detachment, where the self is just an idea that can be changed at will, is a true act of sorcery; and the most difficult of all. When the idea of the self retreats, sorcerers have the energy to align themselves with intent and be more than what we believe is normal. Women, because they have a womb, can focus their attention with great facility on something outside their dreams while dreaming," she explained: “That’s precisely what you have been doing all along, unbeknownst to yourself. That object becomes a bridge that connects you to intent.”
“And what object do I use?”
There was a flicker of impatience in her eyes. Then she said that it was usually a window or a light or even the bed.
“You’re so good at it that it is second nature with you,” she assured me: “That’s why you have nightmares. I told you all this when you were in a deep state of dreaming-awake, and you understood: As long as you refuse to focus your attention on any object prior to sleeping, you don’t have bad dreams.”
“You are cured, aren’t you?” she asked.
My initial reaction, of course, was to contradict her. However, upon a moment’s thought, I could only agree with her: After my meeting with them in Sonora, I had been fairly free from nightmares.
“You’ll never be really free from them as long as you persist in being yourself,” she pronounced: "What you should do, of course, is to exploit your dreaming talents deliberately and intelligently. That’s why you’re here. And the first lesson is that a woman must, through her womb, focus her attention on an object. Not an object from the dream itself, but an independent one, one from the world prior to the dream. Yet, it isn’t the object that matters," she hastened to point out: “What’s important is the deliberate act of focusing on it, at will, prior to the dream and while continuing the dream.”
She warned me that although it sounded simple enough, it was a formidable task that might take me years to accomplish.
“What normally happens is that one awakens the instant one focuses one’s attention on the outside object,” she said.
“What does it mean to use the womb?” I interjected. “And how is it done?” “You are a woman,” Esperanza said softly. “You know how to feel with your womb.”
I wanted to contradict her, to explain that I didn’t know anything. Before I could do so, however, she went on to explain that in a woman, feelings originate in the womb.
“In men,” she claimed, “feelings originate in the brain.”
Esperanza poked me in the stomach and added, “Think about it. A woman is heartless except with her brood because her feelings are coming from her womb. In order to focus your attention with your womb, get an object and put it on your belly or rub it on your genitalia.”
Esperanza laughed uproariously at my look of dismay, then, in between fits of laughter, chided me:
"I wasn’t that bad. I could have said that you need to smear the object with your juices, but I didn’t. Her tone serious again, she continued, “Once you establish a deep familiarity with the object it will always be there to serve you as a bridge.”
