天有五行御五位，以生寒暑燥湿风，人有五脏化五气，以生喜怒忧思恐。故五运之气，内应人之五脏。诸
风掉眩，皆属于肝；诸寒收引，皆属于肾；诸湿肿满，皆属于脾；诸气 郁，皆属于肺；诸痛痒疮，皆属于心
是也。诸厥固泄，皆属于下，谓下焦肾肝之疾也。诸痿喘满，皆属于上，谓上焦心肺之疾也。此皆五脏之疾，
病机由于内动者也。天之三阴三阳化六气，以生寒暑燥湿风火，内应人之六腑，外引十二经络。诸热瞀 ，皆
属于火，手少阳三焦经也；诸禁鼓栗，如丧神守，皆属于火，手少阴心经也；诸逆冲上，皆属于火，手厥阴心
包经也；诸痉项强，皆属于湿，足太阳膀胱经也；诸腹胀大，皆属于热，足太阴脾经也；诸躁狂越，皆属于火，
足阳明胃经也；诸暴强直，皆属于风，足厥阴肝经也；诸病有声，鼓之如鼓，皆属于热，手太阴肺经也；诸病
肿，疼酸惊骇，皆属于火，手阳明大肠经也；诸转反戾，水液混浊，皆属于热，手太阳小肠经也；诸病水液，
澄澈清冷，皆属于寒，足少阴肾经也；诸呕吐酸，暴注下迫，皆属于热，足少阳胆经也。此皆十二经络之邪，
病机由于外入者也。刘河间以此着书，漫然不分所属，殊不深考，何也？楼氏但纠其治法之偏，而未及乎此，
故并为正之云尔。
Heaven possesses the Five Phases (Wood, Fire, Earth, Metal, Water) that govern the five directions, thereby generating Cold, Heat, Dryness, Dampness, and Wind. The human body possesses the Zang Organs (Heart, Liver, Spleen, Lung, Kidney) that transform the Five Qi, thereby generating Joy, Anger, Worry, Thought, and Fear. Thus, the Qi of the Five Movements internally corresponds to the human Zang Organs. All wind-related tremors and dizziness belong to the Liver; all cold-related contraction and pulling belong to the Kidney; all dampness-related edema and fullness belong to the Spleen; all qi-related stagnation belongs to the Lung; all pain, itching, and sores belong to the Heart. This is the case. All jue (cold extremities/reversal) and retention or incontinence belong to the Lower Jiao (Lower Burner), referring to diseases of the Kidney and Liver in the Lower Jiao. All wei (flaccidity syndromes), panting, and fullness belong to the Upper Jiao (Upper Burner), referring to diseases of the Heart and Lung in the Upper Jiao. These are all diseases of the Zang Organs, where the pathogenesis arises from internal movement. Heaven's Three Yin and Three Yang generate the Six Qi (Wind, Cold, Summer-Heat, Dampness, Dryness, Fire), thereby producing Cold, Summer-Heat, Dryness, Dampness, Wind, and Fire, which internally correspond to the human Fu Organs (Hollow Organs) and externally influence the Twelve Meridians. All heat-related mao (dizziness/mental confusion) belong to Fire, corresponding to the Hand-Shaoyang Sanjiao (Triple Energizer) Meridian; all jin (stiff mouth/jaw clenching), drumming shivers, and loss of spiritual control belong to Fire, corresponding to the Hand-Shaoyin Heart Meridian; all counterflow rushing upward belong to Fire, corresponding to the Hand-Jueyin Pericardium Meridian; all spasm and neck stiffness belong to Dampness, corresponding to the Foot-Taiyang Bladder Meridian; all abdominal distension and enlargement belong to Heat, corresponding to the Foot-Taiyin Spleen Meridian; all restlessness, mania, and unruliness belong to Fire, corresponding to the Foot-Yangming Stomach Meridian; all sudden rigidity belong to Wind, corresponding to the Foot-Jueyin Liver Meridian; all diseases with sounds, where percussion yields a drum-like sound, belong to Heat, corresponding to the Hand-Taiyin Lung Meridian; all swelling, painful soreness, fright, and alarm belong to Fire, corresponding to the Hand-Yangming Large Intestine Meridian; all twisting, reverse flexion, and turbid fluids belong to Heat, corresponding to the Hand-Taiyang Small Intestine Meridian; all clear and cold fluids belong to Cold, corresponding to the Foot-Shaoyin Kidney Meridian; all vomiting of sour fluid, sudden diarrhea with tenesmus, belong to Heat, corresponding to the Foot-Shaoyang Gallbladder Meridian. These are all pathogens affecting the Twelve Meridians, where the pathogenesis arises from external invasion. Liu Hejian wrote books based on this but indiscriminately failed to distinguish their respective meridians, lacking deep investigation. Why? Lou Ying only corrected the bias in treatment methods but did not address this issue, so I hereby correct it accordingly.
