Yuki, The Participation of the Conscious in Spontaneous Communication Our revolutionary human nature also gives us another marvelous opportunity: to accompany with our consciousness that communication with spontaneous perception. In the practice of Yuki, we pay attention to communication through spontaneous sensitivity to another person (or to ourselves) involving our awareness, and especially so by use of the hands. Liberation of the hands was essential in the energetic conversion process experienced by our species. Without them, we could not make instruments, a key issue for the enhancement of our mental activity and the development of consciousness and of culture. No other species had this [degree of] evolution. The involvement of the hands increases communication with our own abilities of perception and with those of other people, as well as our accuracy of perception, because the hands are themselves a direct tool of our brains and our consciousness. In fact, we all know about their participation in this type of communication: When we have stomach pain or toothache, we put out the hand on the belly or cheek. Feeling a stiff neck, without thinking, we put our fingers on this area. In the moments when we feel weak, as if lacking in strength in the lower abdomen, we hug that whole region with the forearm. If you feel sadness, something causes you to get your hand on center chest. When a child thinks of an answer for an exam, he puts his hand on his head. When someone has a strong disappointment, we accompany her with a hand on her back. We accompany a bedridden patient by taking his hand ... This instinctive and exclusive ability of our human nature has been and is still used with other approaches and other efforts (healing, energetic, and spiritual). But Noguchi realized that by simply allowing the hands to accompany the awareness of our body, our organism retrieves the ample richness of its spontaneous state. Yuki practice takes place in any part of the CVP (cranium/vertebrae/pelvis) and bodily members. When done with another person, the receiver is most commonly stretched face down and the actor—or performer—, seated at the receptor’s left side, places the hands on the receiver’s back. The role of the actor is to perceive a sensibility to the other person’s world and to communicate with that sensitivity, allowing the hands to rest wherever intuition and the actor’s own sensitivity lead. The actor gradually notices the status of the recipient's body: the breathing, internal vibration, heat or cold, the degree of hardening of tissues, the status of the psyche ... The recipient feels some stiffness in the spinal axis (a rigidity not felt before without the actor’s attentiveness to his back) and at the same time will notice a pleasant sensation in those places receiving attention, and serenity in the psyche ...
As practice progresses, the performer perceives and focuses on the areas of greatest tension, while that very communication guides her toward greater accuracy. The receiver will also note where and how the PET (“particular excessive tension”) is accumulated in his body and awakens in him the desire to regain his range of motion. When, in this communication, coordination is achieved between the sensitivities of both actor and receiver (in rhythm, vibration, respiration, pressure, angle, area ...), areas of accumulated PET experience an increase of activation, thus regaining natural movement. As a result—that is, not by the intention to relax or balance, to relieve ailments, to cure or to heal, but precisely by a simple concentration—tissues and organs regain their mobility, and the mental overstimulation associated with these subsides. The person feels a natural state of being, recovering health and vitality. The practices of Katsugen and Yuki are very simple and require neither major technique nor prior knowledge, but rather only the recuperation and cultivation of a capacity we all possess and that is our birthright. Finally, in both practices, we basically intend to do nothing, but simply attend and accompany with our consciousness the spontaneous movement and awareness of our particular human nature. Gyoki It is a traditional practice in the East, signifying the training of the “ki”. It is done in many ways, including simple and easy or complex and methodical, which ultimately aim to recover the natural scope of chest-abdominal breathing and its tendency to be curtailed due to the problem of PET. In seitai culture, the practice of Katsugen Undo and Yuki together becomes something very simple. (Seitai Barcelona: Avinguda República Argentina nº 28, esc. dcha., pral. 1ª) trans. E.
