本无病也，而疑之成病，积想成因，悬拟成象，则无病者真以为有病矣。彼疑之，我亦疑之，何以名之为
医？本无病也,而诈之为病，困顿其状，呻吟其声，则无病者，真以
为有病矣。彼诈焉，我受其诈焉，何以名之为医？而欲使疑者知其为疑，多方以解其疑，而疑者不疑；诈者知
其为诈，直言以指其诈，而诈者不诈。亦惟决于脉，视其缓而已矣。盖有莫解之症，必有莫解之脉，疑则必疑
为莫解之症，而何以诊其脉无恙也，其为疑必矣；有莫起之 ，必有莫起之脉，诈则必诈为莫起之 ，而何以
诊其脉如常也。其为诈必矣。杯中蛇影，挂弓即解，疑者无所施其疑；灸难分痛，见艾即愈，诈者无所用其诈。
精与脉理者，又何疑诈之我欺也哉？！
代脉关乎寿，结脉因乎寒，促脉因乎热。平脉歇止，则不关乎寿与寒热，亦自有说。盖一呼一吸，脉来
六寸，血营气卫，息数一万三千五百通，脉行五十度，是为一周。稍为痰气所凝，则脉为之一止。非如代之止
有常数，结促之止由迟数而得也。天地万古不老，而有岁差之数；日月万古长明，而有相食之时。岁差、相食，
曾何损于天地日月也哉！
万物之生，负阴而抱阳，阴阳调和，谓之无病。亦
有生来脉旺，谓之纯阳，名曰寿脉，此《脉经》所以言者。有纯阳，则有纯阴，此《脉经》所未言者。余弱冠
时。常至一地，见二妇人，一妇二子，一妇三子，家皆饶裕。余切其脉，按之至骨，丝微欲绝，问其体，一毫
无病。过十年，再至其地，二妇之子，皆入胶庠，家亦丰浓。再诊其脉，依然故吾也。过十年，三至其地，一

本来没有疾病，却因为怀疑而将其当作疾病，长期思虑形成病因，凭空想象形成病象，于是原本无病的人真的以为自己病了。别人产生疑虑，我也跟着疑虑，这怎么能称为医生呢？本来没有疾病，却故意伪装成疾病，装出困顿痛苦的样子，发出呻吟的声音，于是原本无病的人，真的被当作有病的人。别人进行欺骗，我却受其欺骗，这怎么能称为医生呢？要想让那些疑心重的人知道他们是在疑神疑鬼，就要用多种方法来解除他们的疑虑，从而使他们不再多疑；要让那些装病的人知道自己在装病，就要直言不讳地指出他们的欺诈行为，从而使他们停止装病。这一切的判断最终都取决于脉诊，只要观察脉象是否从容和缓即可。因为如果有无法解释的症状，必然有无法解释的脉象；如果说是疑病，那一定是怀疑为无法解释的症状，但为什么诊察脉象却安然无恙呢？这必定是疑病；如果有无法治愈的疾病，必然有无法治愈的脉象；如果说是诈病，那一定是伪装成无法治愈的疾病，但为什么诊察脉象却如常人一样正常呢？这必定是诈病。就像杯中的蛇影，看到弓就解除了疑惑，疑病者就无法施展他们的疑心；就像艾灸难以区分疼痛（指诈病者假装怕痛），见到艾草就痊愈了，诈病者就无法使用他们的欺诈手段。精通脉理的人，又怎么会被我这种疑诈所欺骗呢？！
代脉关乎寿命长短，结脉因于寒邪，促脉因于热邪。平和之人的脉象出现间歇，则与寿命、寒热无关，自有其道理。大概一呼一吸之间，脉气运行六寸，血行营内，气行卫外，呼吸次数共一万三千五百次，脉气运行五十周，这是一周天。稍微被痰湿或气机阻滞，脉气就会出现一次停顿。但这不像代脉那样有固定的常数，也不像结脉、促脉那样由迟脉或数脉衍生而来。天地万古长存而不老，但有岁差的现象；日月万古长明，但有日食月食的时候。岁差和日食月食，对天地日月有什么损害呢？
万物的生长，背负阴而怀抱阳，阴阳调和，就称为无病。也有生来脉象旺盛的，称为纯阳，名为寿脉，这就是《脉经》中所说的。有纯阳，就有纯阴，这是《脉经》所未曾言及的。我二十岁左右时，常去一个地方，见到两位妇人，一位有两个儿子，一位有三个儿子，家境都很富裕。我切她们的脉，按到骨头处，脉象细微几乎要断绝，询问她们的身体状况，毫无病痛。过了十年，再次来到这个地方，两位妇人的儿子，都进入了官学读书，家境也更加丰隆。再次诊察她们的脉象，依然和以前一样。又过了十年，第三次来到这个地方，一位妇人的儿子已经考中举人，家业比昔日加倍丰厚，诊察她的脉象，依然如初。距今又十多年过去了，两位妇人头发花白齐眉，满眼都是穿着青衫的学子（指子孙有成），她们的发达更是不可估量。《脉经》注解说纯阳是寿脉，却不知道纯阴也是富贵、福寿的脉象。

There is no disease originally, yet suspicion transforms it into a perceived illness. Accumulated thoughts become the cause, and hypothetical scenarios form symptoms, so that those who are actually healthy truly believe they are ill. If others suspect, and I also suspect, how can this be called medicine? There is no disease originally, yet one feigns illness, portraying a state of exhaustion and making groaning sounds, so that those who are actually healthy are truly treated as if they were ill. If others deceive, and I accept their deception, how can this be called medicine? To make those with suspicions realize they are merely suspicious, one must employ various methods to resolve their doubts, so that the suspicious cease to doubt; to make those who feign illness realize they are deceiving, one must point out their fraud directly, so that the deceivers cease their pretense. All this depends on pulse diagnosis: observe whether the pulse is slow and relaxed (Huan Mai). For there are symptoms that cannot be explained, and necessarily there are pulses that cannot be explained. If it is suspected illness, it must be suspected as an unexplainable symptom, yet why is the pulse diagnosed as safe and sound? It must be suspected illness. For there are illnesses that cannot recover, and necessarily there are pulses indicating non-recovery. If it is feigned illness, it must be feigned as an incurable illness, yet why is the pulse diagnosed as normal? It must be feigned illness. Like the shadow of a snake in a cup, seeing the bow resolves the suspicion, leaving the suspicious person with no basis for doubt; like moxibustion where pain cannot be distinguished (in cases of feigned pain), seeing the mugwort leads to recovery, leaving the deceiver with no use for their trickery. Those proficient in pulse theory, how could they be deceived by such suspicions or deceptions?!
The Dai Pulse (Intermittent Pulse) relates to longevity, the Jie Pulse (Knotted Pulse) arises from cold, and the Cu Pulse (Rapid-intermittent Pulse) arises from heat. In a healthy individual, pulse interruptions do not relate to longevity or cold/heat, but have their own explanation. Generally, during one exhalation and one inhalation, the pulse travels six cun. Blood nourishes the Ying (Nutritive) level, while Qi guards the Wei (Defensive) level. Over 13,500 breaths, the pulse circulates fifty times, completing one great cycle. If slightly congealed by phlegm or qi stagnation, the pulse may pause once. This is not like the Dai Pulse which has a fixed constant interval, nor like the Jie and Cu pulses which arise from slow or rapid rates. The heaven and earth exist eternally without aging, yet there is the phenomenon of axial precession (Sui Cha); the sun and moon shine eternally, yet there are eclipses. Do axial precession and eclipses harm the heaven and earth at all?
All things are born carrying Yin and embracing Yang. When Yin and Yang are harmonious, it is called health. Some are born with vigorous pulses, called Pure Yang, named as a pulse of longevity; this is what the *Mai Jing* (Pulse Classic) states. If there is Pure Yang, there must be Pure Yin, which the *Mai Jing* did not mention. When I was young (around twenty years old), I often visited a place where I saw two women: one had two sons, the other three sons, and both families were wealthy. I palpated their pulses; pressing to the bone, the pulses were thread-like and nearly imperceptible. Upon asking about their physical condition, they reported no illness whatsoever. Ten years later, I returned to that place. The sons of both women had entered the government schools (Jiao Xiang), and their families were even more prosperous. I re-diagnosed their pulses, and they remained exactly as before. Another ten years passed, and I visited a third time. One woman’s son had passed the provincial examination (becoming a Xiucai/Juren), and her family wealth had doubled compared to the past. Diagnosing her pulse, it remained unchanged. More than ten years have passed since then. Both women now have white hair reaching their eyebrows, and their eyes are filled with scholars (Qing Jin, referring to successful descendants). Their future prosperity is incalculable. The *Mai Jing* annotates Pure Yang as a pulse of longevity, unaware that Pure Yin is also a pulse of wealth, honor, and longevity.
