The purpose of Taoism has always been to live feeling and taking care of the vital energy which animates us. Nature is a fine and detailed expression of the richness of the Tao, which in its original state presents no differences.
From the sacred Unity emerge the observer and that which is observed, the yin and the yang. The dark emptiness gleams and, in the change from darkness to light, from day to night, in the change of seasons, we fragment its non-existent difference or infinite movement into five moments. As human beings we feel those same changes in our body. The changes become painful and the cycles of nature do not correspond to our own maladjusted cycles. Life becomes more difficult and the five moments are filled with excesses in some places, while in others they are empty.
Winter and the seed that holds its vital potential are kept in the kidney so that they can emerge in spring. The liver expands, full of enthusiasm at the charm of sunrise. The intensity of summer makes us celebrate and laugh, our hearts filled with joy: the best is delivered early to be gathered later with the midday sun and the reflection it brings. With wisdom we arrive at adulthood, when life tempers the color of the years and the experience of memory. Our lungs breathe deeply and slowly, feeling the subtlety of the touch of the Chi. Sleep and cold numb us in the ecstasy of Unity.
As far as Chinese medicine is concerned, our liver, which is related to the expansion of spring, is completely blocked in the face of how intense the resistance presented by identity is. Blockage generates heat and symptoms such as frustration, tension, stress and anxiety. Many habitual digestive disorders have to do with liver problems which invade the spleen and irritate the stomach. With time, neither work, nor personal beliefs, nor distractions can fill the biggest emptiness there is: the absence of the touch of the Tao. Living happens without the joy and health typical of childhood; our kidneys are exhausted due to the excesses in the liver explained above and reserves are never replenished by the forgotten Chi. The functioning of the heart, in accordance with emotions, is adversely affected. Syndromes involving excess or heat, or deficiency and cold, include conditions such as anginas, strokes and cardiac insufficiency, for example.
This is a small example of how human beings become inoperative in relation with nature, due to a lack of harmony with the five movements of the Unity and their symbolism in the ancient theory of the five organs. Acupuncture acts upon organs and entrails; more specifically, on the channels through which the vital activity of these organs flows, propeled by the Chi. In them we may find points of agreement with the five movements or elements. They can be located in even members, in front or behind, on one side or the other, up or down, by applying techniques based on the notions of excess or deficiency, man and disease.
