八、或问、七节之傍、中有小心或指下第七节命门穴为小心者有以小心为志心者、有以小心为少火、以少火为相火者、
何纷纷之不一耶、请为悉之
生生子曰∶此出《内经·刺禁论》，启玄子注曰∶“小心者，真心神灵之宫室也。”又注《阴阳类论
篇》。有曰新校正云∶按《太素》小心作志心，杨上善以志心为肾神，故乃倒数脊骨下七节认为小心，顾命
门穴乃十四椎间，即以下逆数之，亦在第八节矣，非第七节也。又不思《经》曰∶“伏鼓不浮，上空志心”
（此阴脉盛而阳气弱，故上控于心，如奔豚积气瘕疝之类是也）。启玄子注曰∶“脉伏鼓击，而不上浮，是
心气不足，故上控引于心而为病也。”此注良是。设为肾而言，则当无“上空”二字
矣。此杨上善之误，故后人即以命门为小心，认小心为少火，认少火为相火，颠倒无限，皆由此一
误也。或曰∶然则小心果为何物？余曰∶滑伯仁经度篇心经注下有云∶心系有二∶其一上与肺相连
，入肺两大叶间；其一由肺系而下，曲折向后，并脊膂细络相连，贯脊髓，正当七节之间，下与肾
相通。盖五脏系皆通于心，心通五脏系也。又按五内图，心系果如所云。据此观之，小心即心包络
也。何一阳亦谓手厥阴心包络发原正在心五椎下二节，七节之傍，正与膻中平对，井不可紊。设如
彼逆数之，则心当在十五椎，肺在十九椎下，自《素问》以来，未尝闻此倒数法也。《灵枢经》曰∶
“膻中者，心主之宫城也。”此与启玄子注真心神灵之宫室相孚，以心系并脊膂贯脊髓，正当七节之
间也。彼倒数下七节，始于杨上善，继而何一阳《医学统宗》已辩其非，余不复赘。

八、有人问：“七节之傍，中有小心”，有人指下第七节的命门穴为“小心”；有人将“小心”解释为“志心”；有人将“小心”解释为“少火”，又将“少火”解释为“相火”。为何说法如此纷乱不一？请详细解说。
生生子说：这一说法出自《内经·刺禁论》。启玄子（王冰）注释说：“‘小心’，是真心神灵居住的宫室。”他又在注释《阴阳类论篇》时提到，新校正说：按《太素》一书，“小心”写作“志心”。杨上善认为“志心”是肾神，所以从下往上倒数脊骨第七节认为是“小心”。但是，命门穴位于第十四椎之间，如果从下逆数，也在第八节了，并非第七节。而且他不思考《内经》中说：“脉伏而鼓动不浮，上部牵引至志心”（这是阴脉盛而阳气弱，所以上部牵引于心，如奔豚、积气、瘕疝等病证）。启玄子注释说：“脉象伏而鼓击，却不上浮，这是心气不足，所以上部牵引引致心病。”这个注释是正确的。如果是就肾脏而言，就不应该有“上空”这两个字了。这是杨上善的错误，所以后人就把命门当作“小心”，把“小心”当作“少火”，把“少火”当作“相火”，颠倒混乱无穷无尽，都源于这一个错误。
有人问：那么“小心”究竟是什么东西呢？我说：滑伯仁在《经度篇》心经注下有云：“心系有两个：一个向上与肺相连，进入肺的两片大叶之间；另一个由肺系向下，曲折向后，沿着脊柱和背部细络相连，贯穿脊髓，正当第七节之间，向下与肾相通。大概五脏的系带都通于心，心也连通五脏的系带。”又按照五脏内景图，心系的形状果然像所说的那样。据此看来，“小心”就是心包络（保护心脏的外围组织）。何一阳也说手厥阴心包络的发源处正在心下方第五椎下两节，即第七节旁边，正与膻中穴平对，绝不能混乱。如果像他们那样从下逆数，那么心就在第十五椎，肺在第十九椎下，自从《素问》以来，从未听说过这种从下逆数的方法。《灵枢经》说：“膻中，是心主的宫城。”这与启玄子注释的“真心神灵居住的宫室”相符，因为心系并连脊柱和背部，贯穿脊髓，正当第七节之间。那种从下逆数七节的方法，始于杨上善，后来何一阳在《医学统宗》中已经辩驳其错误，我不再赘述。

8. A question was asked: "Beside the seventh vertebra, there is the 'Xiaoxin' (Lesser Mind)." Some point to the Mingmen (Gate of Life) acupoint at the lower seventh vertebra as the "Xiaoxin"; some interpret "Xiaoxin" as "Zhixin" (Will Mind); some interpret "Xiaoxin" as "Shaohuo" (Ministerial Fire), and further interpret "Shaohuo" as "Xianghuo" (Ministerial Fire). Why are these interpretations so disparate? Please explain in detail.
Shengshengzi said: This statement originates from the *Stinging Forbidden Points* chapter of the *Neijing* (Classic of Internal Medicine). Qixuanzi (Wang Bing) annotated: "'Xiaoxin' refers to the palace where the true heart spirit resides." In his annotation of the *Yin Yang Lei Lun* chapter, he mentioned that the New Corrections state: According to the *Taisu*, "Xiaoxin" is written as "Zhixin". Yang Shangshan considered "Zhixin" to be the kidney spirit, thus counting backwards from the lower end of the spine to the seventh vertebra to identify it as "Xiaoxin". However, the Mingmen acupoint is located between the fourteenth thoracic vertebrae; if counted backwards from below, it would also be at the eighth vertebra, not the seventh. Moreover, he failed to consider that the *Jing* (Classic) states: "If the pulse is deep, thumping, and does not float, it affects the upper part, reaching the Zhixin" (This indicates excessive yin pulses and weak yang qi, causing upward traction to the heart, similar to conditions like Ben Tun [running piglet], accumulated gas, or hernias). Qixuanzi annotated: "When the pulse is deep and thumping but does not float upwards, it signifies insufficient heart qi, leading to upward traction and disease in the heart." This annotation is correct. If this were referring to the kidney, the words "affects the upper part" would not exist. This is an error by Yang Shangshan; consequently, later scholars equated Mingmen with "Xiaoxin", "Xiaoxin" with "Shaohuo", and "Shaohuo" with "Xianghuo", creating infinite confusion and inversion, all stemming from this single error.
Someone asked: Then what exactly is "Xiaoxin"? I replied: Hu Bo Ren, in his annotations on the Heart Meridian in the *Jing Du Pian*, stated: "The Xin Xi (Heart Connections) has two parts: one connects upwards to the lungs, entering between the two large lobes of the lungs; the other descends from the lung connections, curves backward, connects via fine networks along the spine and back, penetrates the spinal cord, lying exactly between the seventh vertebrae, and communicates downward with the kidneys. Generally, the connections of the five zang organs all connect to the heart, and the heart connects to the connections of the five zang organs." Furthermore, according to the diagrams of the internal organs, the shape of the Xin Xi is indeed as described. Based on this, "Xiaoxin" is the Xin Bao Luo (Pericardium). He Yiyang also stated that the origin of the Hand Jueyin Pericardium Meridian is precisely two segments below the fifth thoracic vertebra of the heart, beside the seventh segment, level with the Tanzhong (Conception Vessel 17) acupoint; they must not be confused. If one were to count backwards as they did, the heart would be at the fifteenth vertebra, and the lungs below the nineteenth vertebra. Since the *Suwen* (Basic Questions), no such method of backward counting has ever been heard of. The *Ling Shu Jing* (Spiritual Pivot) states: "Tanzhong is the palace city of the Heart Master." This aligns with Qixuanzi's annotation of the "palace where the true heart spirit resides," because the Xin Xi connects to the spine and back, penetrating the spinal cord, lying exactly between the seventh vertebrae. The method of counting seven segments downwards from the bottom originated with Yang Shangshan, and He Yiyang had already refuted its errors in his *Yi Xue Tong Zong*; I will not add further details.
