TL;DR: The I Ching is not a diagnostic tool for disease, but a philosophical system that helps us understand the operation of the body and mind. As Nhật Nguyệt reads them, the principle of balancing yin and yang and hexagrams like the Well point to nurturing life and cultivating inner resources for sustainable well-being.
Applying the I Ching to Health: From the Tỉnh (Well) Hexagram to Yin-Yang Balance
How are the I Ching and the body connected?
The I Ching (Kinh Dịch), with its system of 64 hexagrams, is likened to a mirror reflecting every law of movement in the universe. According to scholars of the I Ching, the two lines, yin (- -) and yang (,), are the two most basic symbols, representing two opposing forces that always work together to create all movement. This philosophy does not stop at explaining natural phenomena but is also applied broadly in the field of health care, viewing the human being as a miniature universe.
Health, from the perspective of the I Ching, is not merely the absence of disease but a state of harmony and balance between the opposing forces within the body. When this balance is broken, the body falls into a state of imbalance, creating conditions for illness to arise.
A summary table of the meanings of the I Ching hexagram pairs that the article relates to health states.
| Hexagram | Symbolic meaning | Health connection |
|---|---|---|
| Kiền | Fullness, abundant energy (pure yang) | Resilience, vitality |
| Khôn | Nurturing, sheltering (pure yin) | Rest and recovery |
| Ký Tế | Already complete | Illness will pass |
| Vị Tế | Not yet complete | Right after recovery, relapse or new problems may occur |
What does the Tỉnh (井) hexagram mean in health cultivation?
One of the most valuable images when speaking of health in the I Ching is the Tỉnh hexagram (hexagram number 48). This hexagram describes a well of clear water. The well stays where it is, never moving. The underground spring means the well never runs dry, full without overflowing. Whoever needs water simply comes to draw it, as much as they wish, and the more the water is drawn, the clearer and purer it becomes.
The spirit of the Tỉnh hexagram has been regarded by physicians past and present as a symbol of medical ethics and the method of health cultivation. Like a well, a healthy body needs an inner "underground spring," which is the source of life energy (khí) that is always abundant and properly nourished. Caring for one's health is not about selfishly hoarding energy but about maintaining a circulating flow, a smooth exchange of substances. When we know how to give, to help others, or simply to maintain physical and mental activities, our inner energy also becomes purer and more abundant, just as well water becomes clearer the more it is drawn.
What is synchronicity?
The psychologist Carl Gustav Jung spent many years studying the I Ching and introduced the concept of "synchronicity" to explain its working principle. Jung held that events occurring at the same moment are not merely coincidental but also carry a deeply meaningful connection to one another. He wrote: "The hexagram cast at a particular moment coincides with that moment not only in time but is also identical with the 'quality' of that very moment."
Applying this view to health, we can see that pathological symptoms do not appear as isolated events. They are closely connected to our psychological state, emotions and living environment at that time. A headache may be a manifestation of prolonged stress at work; a digestive problem may reflect anxiety and unease in relationships. This approach encourages us to view the body as a unified whole, in which mental states (C′ and D′) and physical events (A′ and B′) are all manifestations of the same "present circumstance."
Understanding and accepting synchronicity helps us not only treat symptoms but also investigate the deeper root causes of illness, from which we can make appropriate adjustments in lifestyle and thinking.
How do the 64 hexagrams correspond to the 64 states of body and mind?
Each hexagram in the I Ching is a symbol of a state, a specific situation in life. According to physician Nguyễn Chấn Hùng, the 64 hexagrams are precisely "64 situations of life, teaching us the character of the noble person, the conduct of the noble person." This can also be applied to understanding the ceaseless transformation of human health.
- The Kiền (☰) and Khôn (☷) hexagrams: Symbolizing the state of fullness, abundant energy (pure yang) and nurturing, sheltering (pure yin). A healthy body needs a harmonious combination of both elements: resilience, vitality (yang) and rest, recovery (yin).
- The Ký Tế (既济) and Vị Tế (未济) hexagrams: Ký Tế means "already complete," while Vị Tế means "not yet complete." As understood by Nhật Nguyệt, these final two hexagrams show that every health state is not a final stopping point. Illness will pass (Ký Tế), but right after recovery it may relapse or new problems may arise (Vị Tế). This teaches us not to be complacent about our health and always to maintain a cautious spirit, knowing how to adjust and adapt to change.
How does one cultivate health according to the philosophy of the I Ching?
From the above principles, we can draw practical lessons for caring for our health each day:
- Listen to the body: Just as casting a hexagram helps understand a situation, learn to "listen" to your body's signals. Fatigue, aches or negative emotions are all "hexagrams" telling us about an inner imbalance.
- Maintain balance: Seek harmony between work and rest (movement and stillness), between eating and exercise, between social relationships and private time.
- Nourish inner resources: Like the spirit of the Tỉnh hexagram, build a healthy lifestyle as a sustainable "underground spring": a balanced diet, regular exercise, enough sleep and an optimistic spirit.
- View illness comprehensively: When facing a health problem, do not focus only on taking medication to reduce symptoms. Consider the psychological, lifestyle and environmental factors that may have led to that condition.
The I Ching is not a medical textbook, and it should not be used to replace modern medical diagnosis and treatment. However, as a profound system of philosophy and psychology, it provides us with a comprehensive framework of thought for understanding health, from which to live a more balanced, meaningful and healthy life.
