There are eight kinds of major anguish in human life, namely, the so-called eight kinds of suffering - life, old age, sickness, death, grievances, meeting, asking for nothing, love being apart, five bulging radiance - among them, old, sick, dead These four items are basic pains that cannot be escaped. As long as they are sentimental, they must be experienced. Therefore, let us come together from the Buddhist scriptures to understand the causes of illness.
Sickness is a very important experience in life, and the Dharma specifically designed to solve many painful lives has a complete explanation of the causes of the disease.

Sickness is a very important experience in life, and the Dharma specifically designed to solve many painful lives has a complete explanation of the causes of the disease.
Dharma view
In the "Golden Light, Diseases, and Other Diseases", three types of pathogenic factors are mentioned:
1. Four major root causes: The problem caused by the body's own physical factors (or basic elements);
2. Dietary factors: problems caused by diet;
3. Seasonal seasonal factors: Problems caused by the environment.
In the "Non-Viewing and Treating Nine Diseases", we also discuss three causes of illness:
1. Four major lesions: discuss the different phases caused by the four elements;
2. The phase of five internal organs: to describe the different manifestations of diseases caused by dysfunction of the five internal organs;
3. The disease caused by the ghosts and gods: that is, the disease caused by the devil's deeds.
The part discussed in the "Non-Viewing and Treating Nine Diseases" seems to be more focused on the description of "disorders" and "diagnosis". Therefore, it is quite different from the part of "The Golden Light". The "Ghosts and Gods" section discusses the cause of the disease in the spiritual and even the spiritual realm. This is the less commonly talked about part.
In addition, the cause of the disease is also described in the "Zha Ai Jing Jing" volume 15:
Because of the wind
2. From Yin Yin;
3. Speak up;
4. The public cold;
The four major issues lie in the detailed analysis of the diseases caused by the four disharmony.
5. Because of the current incident;
This item is an emotional or spiritual illness.
6. Seasonal seasons; like the aforementioned seasonal factors.
Because the treatment of suffering is really a pressing need for all beings, the field of medicine, which is already very developed in world law, is also trying to solve this problem.
The currently known disease factors can be analyzed as follows:
a. Pathogenic microorganisms: such as various viruses, bacteria, molds, etc.
b. The body's immune function: It means the so-called resistance or constitution.
c. Environmental pollution: toxic waste, chemical substances, radiation, etc.
d. Aging: Many diseases are caused by "aging".
e. Diet (Nutrition): The state of the diet can have many deterministic effects on health.
f. Mental illness: This is a weaker link in the current medical field, but it can be identified with genetics.
g. External injuries: Including many accidents and other injuries.
If we discuss it again, we can classify a and c as environmental factors; b, d, and f can be attributed to gene expression, which is called physical factors.
If we consider e (diet) again, we can find that it is very closely related to the four points a, b, c, d and even to f; because apart from breathing, diet can be said to be the interaction between human and environment. The most common route is that the energy comes in and out, and the communication of material elements depends on the diet, and the performance of the gene is known to have a great relationship with the environment.g This is not only related to the environment, but also often to the personality of the individual ( (Gene) is concerned. In this connection, we can get a concept first, that is, human beings and the environment are inseparably integrated. So then let us look at the Chinese medicine.
TCM theory
Chinese medicine theory believes that the causes of diseases can be divided into -
1. External factors: The "six obscenities"-based wind, cold, heat, humidity, dryness, and fire. This is the "season seasonal factor."
2. Internal factors: This is based on seven emotions: hi, anger, worry, thought, sadness, fear, and panic. Explain the influence of human emotions on physiology.
3. Internal and external factors: Including diet, sexual intercourse, gold edge (this can include trauma or accidents), insects and beasts (including microbes), etc., and widely point out that other factors besides sex and sex.
It can be seen that Chinese medicine is very careful in explaining the seasonal influence on humans and the theory that mental emotions affect health. Maybe in some parts we can find direct evidence (especially bacterial viruses, etc.) to illustrate, but there are also some Some are currently unable to know what their association is. In other parts, in general, Chinese medicine is not far from Western medicine.
From the above explanation of Buddhism and medicine, we can clearly summarize several important factors that affect health:
1. The condition of the environment;
2. Conditionality of genes;
3. The condition of the diet.
If these three conditions are not problematic, and they can be properly matched with the other two conditions, people can live healthily and longevity.
Karma and blessings
In fact, whether it is the Buddhism born in the world, or the medicine of joining the world, the analysis of sickness is very thorough and thorough. In particular, the explanation of matter in medicine is more and more complete due to technological progress.
However, if light depends on medicine, the problem cannot be completely solved because we cannot help but ask: What are the factors that determine the performance of these three conditions or are sufficient?
The answer is: The balance between karma and blessings is growing.
In addition to this answer, how can we find a more complete and more accurate answer? The probability, the chance, the luck, and the Creator? Who can accept this kind of answer with conviction? These are parts of medicine that are difficult to answer. Because of good fortune or small karma, someone grows in a good environment, inherits excellent genes, and enjoys a healthy diet, so they live longer and healthier lives. Because the blessings are shallow or the karma is deep, someone was born in a bad or even war-torn country, or it inherited a defective gene, or it became sick early because of three meals. This kind of answer is simple and complete. It is most consistent with the requirements of the ideal theory in science—simple, with a large scope of application, and with few exceptions. Therefore, to correctly understand the question of why people are sick or healthy, apart from the technical and materialistic answers mentioned above, it is necessary to return to the level of causal karma. Where we have grasped the core of the comparative core, we will not be confused by many complicated phenomena - at least not being deceived by false advertising - and we can get the focus. Knowing where to start and correct efforts can really prevent diseases and improve health.
