We can speak of the chi in a more technical, medical sense.
Your life force, your normal life-force, is your zheng qi, “Essential Chi.” The causes of disease are the six Outside Chi or External Chi (wind, cold, dampness, dryness, and fire), and the seven Emotions (joy, anger, worry, thinking, sadness, fright, and fear). Your Essential Chi should flow in an orderly and harmonious manner; and does so when you are healthy. But the six External Chi and the seven Emotions may disturb this orderly harmonious flow and thus cause certain harmful changes, or illness in your body. For example, when you are cold, your chi can “freeze,” meaning that it is stuck and almost does not flow at all. Or, when you are worried the chi becomes “congested,” meaning that is flows sluggishly or somewhat disorderly.
The Emotions are a kind of function, a chi in themselves. Like the six External chi the seven Emotions affect the flow of your energy. For example, when you are angry your chi goes up, when you are happy the chi goes down.
Strong Essential Chi is important for good health. The six External Chi and the seven Emotions constantly best you; but they will normally not affect you if your Essential Chi is strong. Should one or more of the six External Chi or the seven Emotions be excessively strong it may affect you even though your Essential Chi is strong; but the effect will be less harmful than it would be were your Essential Chi weak.
The zheng qi, essential Chi, is both the xian tian zhi qi, Before Sky Chi, and the hou tian zhi chi, after Sky Chi, together. The constitute your “Life-Force.”
When you eat food (this includes drinking liquids) your body processes the ingested food and from it produces essences; and when you breath you take in air. Both the air you breathe and the essences you derive from food are important factors in the medical understanding of chi.
Level 1: Paraphrasing-
Practice Tai Chi for preventative care.
Your normal life-force is your “Essential Chi.” There are six causes of disease outside of your body. These External Chi are wind, cold, wetness, dryness, and fire. We have seven Emotions; joy, anger, worry, sadness, disgust, and fear. When you are healthy your Essential Chi flows in order and in harmony. However, the six External Chi and the seven Emotions can disrupt order and harmony. This harmful change can make you sick. When you are cold your chi can freeze, and stop your essential flow. When you are worried your chi becomes congested, blocking and slowing your essential flow.
The seven Emotions affect the orderly and harmonious flow of your energy. When you are angry your chi raises, and when you are happy your chi lowers.
Strong Essential Chi is critical to your health. The six External Chi and the seven Emotions Chi have power over you. As a rule they will not affect you if your Essential Chi is strong. You may get sick if one or more of the six External Chi or the seven Emotions are really strong. However, you will lessen the sickness if you have a strong Essential Chi.
Your essential Chi is a mix of before Sky Chi and after Sky Chi. This is your “Life-Force.”
When you eat and drink you create your life blood. Breathing gives you air. Both are important in the medicine of chi.
Level 2: Explicating-
- State the main point.
- You will be healthy if you have a strong Essential Chi.
- In other words…. what you eat and drink and how you move and breath is essential to having a healthy Life-Force. Your Essential Chi flows in order and harmony.
- For example… The practice Tai Chi improves your health and therefore can be practiced for preventative care.
