原文：脉之所居深不见者,刺之微内针而久留之,以致其空脉气也。脉浅者勿刺,按绝其脉乃刺之,无令精出,独出其邪气耳所谓三刺则谷气出者,先浅刺绝皮,以出阳邪;再则阴邪出者,少益深,绝皮致肌肉,未人分肉间也;已人分肉之间,则谷气出。故刺法》曰:始刺浅之,以逐邪气而来血气,后刺深之,以致阴气之邪最后刺极深之,以下谷气。此之谓也。 故用针者,不知年之所加,气之盛衰,虚实之所起,不可以为工也。 翻译:脉络分布在深部而不显现于外、不能用肉眼看见的,在针刺时,要轻微地进针,刺入其内,并长时间留针,以使孔穴中的脉气上行而产生针感。脉络分布在浅部而现于外的,就不能直接针刺,必须先按压隔绝其脉,避开血管,然后才可以进行针刺。只有这样,才不致出血,也就不使精气外泄,而只将邪气去除。所谓“三刺”就是可以使谷气出而产生针感的针刺法,就是浅刺进入皮肤,以宣泄卫分的阳邪;然后再刺入一些,以使阴邪能够外出,而其刺入的深度,也只是稍稍深一些,比皮肤的浅层略深,透过了皮肤,接近了肌肉,但还不能达到肌肉之间;最后再将针尖深入到分肉之间,这时就会使谷气出而产生酸麻肿胀等针感。所以古医书《刺法》中曾说“开始时浅刺皮肤,可以驱逐浅表的邪气,而使血气流通;此后再刺入较深,就可以宣散阴分的邪气;最后刺入极深,到了一定的深度,就可以通导谷气而产生针感。其内容说的正是这种“三刺”的针刺法。 所以运用针法来治疗疾病的医者,不知道每年风寒、暑、湿、燥、火六气增加的时期,每一节气中六气盛衰的情况,及因气候变化而引起病情的虚实变化,就不能成为良医。 英语翻译：If the vein is distributed in the deep part and does not appear outside and can not be seen by the naked eye, the needle should be inserted slightly and kept for a long time, so as to make the pulse gas in the hole go up and produce a needle sense. If the vein is distributed in the superficial part and appears outside, it can not be directly needled. Only in this way can we not bleed, nor let out the essence, but only remove the evil. The so-called "three needling" is a needling method that can make the valley Qi come out and produce a needling feeling. It is shallow needling into the skin to release the Yang evil of Weifen. Then it is needling into the skin to make the Yin evil can go out. The depth of needling is only a little deeper than the shallow layer of the skin. It passes through the skin and is close to the muscle, but it can't reach the muscle. Finally, it is needling into the meat, At this time, it will make the Valley gas out and produce the sensation of acid, hemp, swelling, etc. Therefore, the ancient medical book "acupuncture method" once said that "at the beginning, shallow pricking of the skin can expel the superficial evil spirit, and make the blood flow; after that, deep pricking can spread the evil spirit of Yin points; at last, deep pricking, to a certain depth, can dredge the Valley Qi and produce the needle feeling. The content of the acupuncture is exactly the acupuncture method of "three needlings". Therefore, doctors who use acupuncture to treat diseases can't become good doctors if they don't know the increasing period of six Qi of cold, heat, dampness, dryness and fire every year, the ups and downs of six Qi in each solar term, and the changes of the virtual and real conditions caused by climate change. 本文来源：https://www.wddqw.com/doc/79d74667df36a32d7375a417866fb84ae45cc3fe.html
