考，岂不是灵机在脑之证据乎！
关于“灵机（精神意识）和记性（记忆力）不在心而在脑”这一观点，本来不应该多谈，即使能讲清楚，也必然难以被世人接受。如果不想谈论，但有许多疾病，人们不知道是因为“灵机”在前（即脑部功能），而将其归并到心脏上。
有一条管道，进入心脏，从心脏向左转出来，经过肺部进入脊柱，名叫“卫总管”。它前方连通气府和精道，后方连通脊柱，上方连通两肩，中间连通两肾，下方连通两腿。这条管道是储存元气与津液的地方。气的出入，经过心脏，心脏只是气出入的道路，怎么能产生灵机、储存记忆呢？
灵机和记忆力在脑中的原因，是因为饮食化生气血，生长肌肉，其中精汁中清纯的部分，转化为髓，由脊柱骨上行进入脑部，名叫脑髓。盛放脑髓的，名叫髓海。其上方的骨头，名叫天灵盖。两耳与脑相通，所听到的声音归于脑。如果脑气虚弱，脑就会缩小。脑气与耳窍之气不相接应，所以导致虚聋；如果耳窍通向脑的道路中有阻滞，所以导致实聋。
两只眼睛是由脑汁生成的，两眼的眼系像线一样，长在脑中，所见到的事物归于脑。瞳孔呈现白色，是脑汁向下注入眼中，名叫脑汁入目。鼻子与脑相通，所闻到的气味归于脑。如果脑受到风热侵袭，脑汁会从鼻流出，鼻涕浑浊且气味臭秽，名叫脑漏。
看刚出生的小儿，脑尚未发育完全，囟门柔软，眼睛不灵动，耳朵不知道听，鼻子不知道闻，舌头不会说话。等到一周岁，脑逐渐生成，囟门逐渐闭合，耳朵稍微知道听，眼睛稍微有点灵动，鼻子微微知道香臭，舌头能说出一两个字。等到三、四岁，脑髓逐渐充满，囟门长全，耳朵能听，眼睛有灵动，鼻子知道香臭，言语能成句。所以小儿没有记忆力，是因为脑髓未满；老年人没有记忆力，是因为脑髓逐渐空虚。
李时珍说：“脑为元神之府。”金正希说：“人的记忆力都在脑中。”汪庵说：“现在的人每当回忆往事，必定闭上眼睛向上瞪视来思索。”
脑髓中一旦暂时没有气，不仅没有灵机，而且必死一时；一刻没有气，必死一刻。
试看痫症，俗名羊羔风，就是元气一时不能上转入脑髓。抽搐的时候，正是活人有着死的脑袋。所谓活人，是指腹部先没有气，胸中的气不知如何出入，突然向外发散。正在抽搐时，胸中有漉漉的声音，是因为津液在气管中，脑中没有灵机之气来使津液吐纳吞咽，津液逗留在气管中，所以有此声音。抽搐后出现头疼昏睡，是因为气虽然转入脑中，但尚且不足。小儿久病后元气虚弱导致的抽风，大人突然得的气厥，都是由于脑中无气，所以病人毫无知觉。以此参考，这难道不是灵机在脑的证据吗！
Regarding the proposition that "the spiritual mechanism (Lingji, referring to mental activity and consciousness) and memory reside in the brain rather than the heart," this topic arguably should not have been discussed; even if explained clearly, it would likely be difficult to implement or accept. If one wishes not to discuss it, there are many diseases where people fail to recognize that the "spiritual mechanism" originates from the head/brain, instead attributing them solely to the heart.
There is a vessel entering the heart, turning left out of the heart, passing through the lungs into the spine, named the "Wei Zong Guan" (General Manager of Defensive Qi). Anteriorly, it connects to the Qi Fu and Jing Dao; posteriorly, it connects to the spine; superiorly, it connects to both shoulders; medially, it connects to both kidneys; inferiorly, it connects to both legs. This vessel is the repository for Yuan Qi (Original Qi) and Jin Ye (Body Fluids). The entry and exit of Qi pass through the heart; the heart is merely the pathway for Qi's movement, so how can it generate the spiritual mechanism or store memory?
The reason why the spiritual mechanism and memory reside in the brain is as follows: Diet generates Qi and Blood, which nourish muscles. The purest essence of fluids transforms into Marrow (Sui), which travels up the spinal bone into the brain, named Brain Marrow (Nao Sui). The container holding the brain marrow is named the Sea of Marrow (Sui Hai). The bone above it is named the Tian Ling Gai (Heavenly Spirit Cover). The two ears connect to the brain, and all sounds heard return to the brain. If Brain Qi is deficient, the brain shrinks. If the Qi of the brain does not connect with the Qi of the ear orifices, deficiency deafness occurs. If there is obstruction in the pathway connecting the ear orifices to the brain, excess deafness occurs.
The two eyes are generated from Brain Juice. The optic nerves are like threads extending into the brain; all visual objects perceived return to the brain. The whiteness of the pupil is due to Brain Juice flowing downward into the eye, a process named "Brain Juice Entering the Eyes." The nose connects to the brain, and all odors perceived return to the brain. If the brain is affected by Wind-Heat, Brain Juice flows out through the nose; the nasal discharge becomes turbid and foul-smelling, a condition named Nao Lou (Brain Leakage).
Observing newborn infants, their brains are not fully developed; the fontanelle is soft, their eyes lack agility, they do not hear, they do not smell, and their tongues cannot speak. By one year of age, the brain gradually develops, the fontanelle closes, they begin to hear slightly, their eyes show slight agility, they faintly perceive smells, and their tongues can utter one or two words. By three or four years of age, the brain marrow is nearly full, the fontanelle is completely closed, they can hear, their eyes are agile, they perceive smells, and their speech forms sentences. Therefore, children lack memory because their brain marrow is not yet full; the elderly lack memory because their brain marrow gradually empties.
Li Shizhen stated: "The brain is the mansion of the Primordial Spirit." Zheng Jingxi stated: "Human memory resides entirely in the brain." Wang An stated: "People today, when recalling past events, must close their eyes and look upward to ponder."
If there is temporarily no Qi in the brain marrow, not only is there no spiritual mechanism, but death ensues momentarily; if there is no Qi for even an instant, death occurs instantly.
Consider Epilepsy (Xian Zheng), commonly known as Sheep Lamb Wind (Yang Gao Feng); this is precisely when Yuan Qi temporarily fails to ascend and enter the brain marrow. During convulsions, it is as if a living person has a dead brain. The term "living person" refers to the fact that Qi first leaves the abdomen; the Qi in the chest does not know how to enter or exit and suddenly rushes outward. During convulsions, a gurgling sound is heard in the chest because Body Fluids are trapped in the airways. Since the brain lacks the Qi of the spiritual mechanism to facilitate the swallowing and expectoration of fluids, the fluids stagnate in the airways, causing this sound. Headache and drowsiness after convulsions occur because although Qi has entered the brain, it is still insufficient. Convulsive wind in children after prolonged illness due to deficient Yuan Qi, and sudden Qi Jue (Qi Syncope) in adults, are both caused by a lack of Qi in the brain, resulting in the patient having no awareness. Based on this reference, is this not evidence that the spiritual mechanism resides in the brain!
