The Yin-Yang theory makes it evident that the outlook of the ancient Chinese regarding nature and the universe mainly concentrates on process and change. In effect, the Five Element Theory, which is sometimes known as the Five Phase theory, is just a different part of this view regarding change and movement. This concept says that the entire phenomena are produced as a result of the movement of the five elements - earth, wood, fire, water and metal. However, these elements do not form the basic constituents of matter, but are somewhat portrayal of specific attributes that are relevant to particular phase or cycles of change.
In shiatsu jargon, completeness or surplus of Ki resulting in obstruction or excitement in a channel/ meridian or tsubo is denoted as 'jitsu', while lack or bareness of Ki leading to hypo-activity or comparative inertness in any particular channel is called 'kyo'. In order to comprehend what kyo is, we need to deem that all the parts of a living organism look for nourishments by Ki and blood. Therefore, when deficient Ki arrives at any part of the body, that particular body part/ area expresses a requirement for additional Ki.
In addition, any need or requirement (kyo) would ultimately produce a reaction (jitsu) at some place within the body with an endeavour to make up for or fulfill that need. Therefore, kyo is the fundamental reason behind jitsu. To repeat the correlation of hunger, when there is sufficient supply of food, there in no requirement to be busy to immediately pack up the food cabinets. Nevertheless, when there is a scarcity of food and start feeling hungry, we start concentrating plenty of our energy as well as resources into obtaining additional food. In this case, the deprived kyo channel area causes intensified activities of 'jitsu' somewhere else.
The matrix of Ki of the body and the mind is composed of the Ki channels within our body and it continuously struggles to maintain a balance. In effect, it desires a smooth circulation of Ki as well as an unproblematic existence. However, our minds, actions as well as the influences of the environment on us occasionally act against this, but still the Ki matrix within us continues to strive for balance within itself. In reality, it takes plenty of endeavour or unfavourable situations to triumph over the synchronization of the body. Nevertheless, when the balance of Ki is lost, we become ill and suffer from diseases.
In effect, the disease itself is an endeavour to reinstate harmony, but occasionally the body and the mind simply does not have the final reserves or determination to become well devoid of help from outside. Therefore, we possess curative systems of a variety of types, counting shiatsu, which facilitate in restoring health or avoiding ailments by means of maintaining the smooth flow of Ki all through the channels or meridians making use of methods to fulfill the requirements of the kyo and, if required, disband or soothe the jitsu. In shiatsu, terms kyo and jitsu are normally confined to portraying the condition of the channels/ meridians and tsubos, but are not made use of to depict abnormalities in the functioning of the organs, which are generally illustrated as Yin-Yang imbalances. This is despite the fact that the alterations of the channels as well as the imbalances in the functioning of the organs occasionally happen to be identical symptoms.
It is much easier to locate the jitsu areas since they experience 'activeness' and when pressure is applied, they react locally. At times, the jitsu areas also stick out from the surface. On the other hand, it is comparatively difficult to find the kyo areas since they exhibit little or no response to touch and generally do not reveal a clear existence on the surface. However, people who are trained in shiatsu are able to see as well as feel kyo in the form of a dent or hollowness on the surface.
