The two eyes of a human being are like the sun and moon in the sky; they observe all things and perceive the minutest details, reaching everywhere. When the sun and moon experience temporary obscuration, it is caused by wind, clouds, thunder, and rain; when the eyes experience temporary blindness, it is caused by harm from the six desires (liù yù) and seven emotions (qī qíng). The eyes are the essence of the five Zang organs (wǔ zàng) and the master of the whole body. Therefore, the five Zang organs are divided into the Five Wheels (wǔ lún), and the Eight Trigrams (bā guà) are divided into the Eight Palaces (bā kuò). The Five Wheels correspond to the Five Elements (wǔ xíng): Metal, Wood, Water, Fire, and Earth. The Liver belongs to Wood, named the Wind Wheel (Fēng Lún), located at the cornea (wū jīng) of the eye. The Lung belongs to Metal, named the Qi Wheel (Qì Lún), located at the sclera (bái jīng) of the eye. The Spleen belongs to Earth, named the Flesh Wheel (Ròu Lún), located at the upper and lower eyelids. The Heart belongs to Fire, named the Blood Wheel (Xuè Lún), located at the canthi (liǎng zī) of the eye. The Kidney belongs to Water, named the Water Wheel (Shuǐ Lún), located at the pupil (tóng shén). As for the Eight Palaces, they have names but no fixed positions. The Gallbladder's Fu organ corresponds to the Heavenly Palace (Tiān Kuò), called Qian (Qián). The Bladder's Fu organ corresponds to the Earthly Palace (Dì Kuò), called Kun (Kūn). The Gate of Vitality (Mìng Mén)'s Fu organ corresponds to the Water Palace (Shuǐ Kuò), called Kan (Kǎn). The Small Intestine's Fu organ corresponds to the Fire Palace (Huǒ Kuò), called Li (Lí). The Large Intestine's Fu organ corresponds to the Mountain Palace (Shān Kuò), called Gen (Gèn). The Sanjiao (Triple Burner)'s Fu organ corresponds to the Marsh Palace (Zé Kuò), called Dui (Duì). The Spleen and Stomach's Fu organ corresponds to the Thunder Palace (Léi Kuò), called Zhen (Zhèn). The Lung's Fu organ corresponds to the Wind Palace (Fēng Kuò), called Xun (Xùn). These constitute the root of the eyes, relying on the eyelid collaterals (bāo luò) for function. Thus, if the five Zang organs accumulate Wind-Heat (fēng rè), or if the Qi of the seven emotions becomes stagnant and does not dissipate, it attacks upward to the eyes, manifesting according to the respective Zang organs. Symptoms may include swelling, itching, photophobia, and excessive tearing, or opacities causing dim vision. There are seventy-two types of eye diseases; one must investigate their source. If it is Wind pathogen, disperse it; if it is Heat, cool it; if it is Qi stagnation, regulate and smooth it. One must absolutely avoid using needles, knives, hooks, or cutting procedures lightly. Occasional cures are merely luck; any error will lead to lifelong affliction. Furthermore, one must not overuse cold/cooling medicines, lest they freeze the Blood Wheel, causing blood to coagulate and stagnate, thereby forming chronic diseases. One must also consider the patient's age and assess the deficiency or excess of Qi and Blood before prescribing medication, ensuring efficacy. For instance, if a person's eyes lack luster due to excessive consumption of raw or cold foods, tonifying medicines should be used to warm the Lower Yuan (xià yuán) and benefit Kidney Water. People in the North suffer from eye diseases most frequently because they are exposed to wind and sand during the day and sleep on heated kang beds at night; the interaction of these two energies causes this condition. Treatment should employ cooling medicines. This is because the innate constitution and climate of the North differ from those of the South. After children suffer from smallpox or chickenpox, toxic vapors stagnate in the Heart and Liver meridians, erupting in the eyes and damaging the pupil. Traditionally, there was no effective treatment. However, if the toxicity floats to the Lung meridian, causing opacities to cover the pupil, it is treatable. I have heard that Sun Taizhen (Sun Simiao) transmitted an immortal prescription that cured one patient's eye disease, leading to nine generations of prosperity for his family. This book truly possesses the miracle of turning stone into gold and the subtlety of clearing clouds to reveal the sun. Those suffering from eye diseases should examine the Five Wheels: if there is excess, purge it; if there is deficiency, tonify it. For example, the Liver belongs to Wood. Wood generates Fire; Fire is the child of Wood. Wood is the mother of Fire. If the Liver meridian is deficient, one should "tonify the mother when deficient." If it is excess, one should "purge the child when excess." This is a sound method. Treating eye diseases essentially involves examining the deficiency and excess of the Mother-Child relationships among Metal, Wood, Water, Fire, and Earth, understanding their generation and restriction cycles, and determining whether to tonify or purge. That is all. The Q&A regarding the seventy-two symptoms is concise and clear; it should be cherished. It truly possesses divine efficacy, curing diseases with a mere touch of the hand.
