This Chapter is a dialogue from the Yellow Emperor's Classic of Internal Medicine, exploring the physiological basis of health, illness, and courage. The Yellow Emperor and Shao Yu discuss how susceptibility to illness varies based on skin, muscle, and complexion, attributing differences in responses to weather and pain to physical constitution rather than solely bravery or cowardice. Shao Yu explains that courage stems from a well-organized internal structure and strong organs, while cowardice results from imbalances and weakness. Finally, they examine how alcohol can temporarily mask cowardice.

This Chapter is an excerpt from The Yellow Emperor's Classic of Internal Medicine, specifically Chapter 49, "The Spiritual Pivot – The Five Colors."

This Chapter is a dialogue from the Yellow Emperor's Classic of Internal Medicine, specifically Chapter 48, "The Spiritual Pivot – Prohibitions on Transmission." It details a student's request for simplified medical knowledge and the master's response, which involves a sacred oath and instruction on acupuncture techniques. The teachings emphasize understanding pulse diagnosis to determine the location and nature of illness (excess/deficiency, tension, etc.), and appropriate treatments using acupuncture, moxibustion, and herbal medicine. The master stresses the importance of mastering the complete system before simplifying it for teaching, highlighting the dangers of incomplete knowledge. The text underscores the secretive and ritualistic nature of knowledge transmission in ancient Chinese medicine.

This Chapter from the Yellow Emperor's Classic of Internal Medicine explores the relationship between organ variations and health. Qi Bo, responding to the Yellow Emperor's inquiries, details how size, position, and firmness of the five zang organs (heart, lungs, liver, spleen, kidneys) and six fu organs influence susceptibility to illness. He explains that these variations, totaling 25, manifest externally and can be observed to diagnose internal conditions. The text further examines how these organs correlate with other bodily components, such as skin, muscles, and bones, to provide a holistic understanding of health and disease. Finally, it discusses the relationship between the five zang and six fu organs and their external manifestations.

This Chapter is a dialogue from the Yellow Emperor's Classic of Internal Medicine, exploring the causes of illness. Shao Yu, a physician, explains that illness arises not solely from external factors like wind and cold, but also from individual vulnerabilities. He uses the analogy of different types of wood reacting differently to weather to illustrate how internal constitution affects susceptibility to disease. Shao Yu describes physical indicators that correlate with a predisposition to various ailments, such as wind conditions, emaciation, chills, fever, and obstructions. The discussion emphasizes both the external triggers and the internal predisposition in the development of disease.

This Chapter from The Yellow Emperor's Classic of Internal Medicine explores the principles of Nine Needles acupuncture. The dialogue between the Yellow Emperor and Qi Bo reveals that mastering these needles mirrors governing a nation, requiring an understanding of yin and yang balance and the interconnectedness of inner and outer states. The text emphasizes observing and understanding the subtle relationships between seemingly disparate elements to achieve harmony and efficacy, whether in acupuncture or governance. Successful practice necessitates discerning inner states from outer manifestations, and vice-versa. The ultimate goal is achieving a state of clear perception akin to a perfect reflection in a still, clear mirror.

This Chapter from The Yellow Emperor's Classic of Internal Medicine explores the relationship between the human body's Qi and the cyclical nature of the four seasons. It explains how daily fluctuations in health correlate with these seasonal patterns, with mornings mirroring spring, noon summer, evenings autumn, and night winter. The text further details a theory of "five transformations," linking the five internal organs to specific colors, sounds, tastes, and seasonal times, informing acupuncture treatment strategies. This system uses the timing of the five elements to guide the selection of specific acupuncture points for optimal healing. Ultimately, the text advocates for aligning treatments with natural rhythms for effective healthcare.

This Chapter from The Yellow Emperor’s Classic of Internal Medicine details the relationship between dream manifestations and imbalances of qi within the body. Qi Bo explains that excess or deficiency in specific organs, or the overall dominance of yin or yang energy, leads to distinct dream imagery. For example, excess liver qi manifests as dreams of anger, while excess lung qi may cause dreams of flying or fear. The text further categorizes dreams based on the location of “rebellious qi,” offering a comprehensive system for diagnosing internal imbalances through dream interpretation. Treatment, according to Qi Bo, involves addressing these imbalances through either draining excess or supplementing deficiencies.

This Chapter is a dialogue from the Yellow Emperor's Classic of Internal Medicine, specifically Chapter 42, "The Spiritual Pivot – Disease Transmission." The Yellow Emperor questions Qi Bo about various healing methods and the progression of disease. Qi Bo explains that while numerous techniques exist, understanding the principles of yin and yang is crucial. He details specific timelines for disease transmission between organs, emphasizing that sequential progression signifies a fatal prognosis, while irregular transmission allows for treatment. The passage highlights the importance of holistic understanding and the limitations of solely relying on individual therapeutic methods.

This Chapter from The Yellow Emperor's Classic of Internal Medicine explores the correspondence between macrocosmic principles (heaven/earth, sun/moon) and the human body's meridians and organs. Qi Bo explains how the twelve leg meridians relate to the twelve months, and the ten hand meridians relate to the ten sun cycles, reflecting yin and yang distribution. The text details specific meridian associations with months and describes how this knowledge guides acupuncture treatment, emphasizing seasonal variations in qi flow. Finally, it clarifies that these correspondences reflect the dynamic interplay of yin and yang, rather than a strict adherence to the five-phase theory.
