天下之妙理寓于跡象之中,實超于跡象之外,彼拘于跡象以索解者,縱于理能窺其妙,實未能窮其極妙也。如九十六號(紹興星期報)陳××,因研究剖gydjdsj.org.cn/wszg/解之學人于十二經(jīng)之起止莫能尋其跡象,遂言《內經(jīng)》所言十二經(jīng)無可考據(jù)。非無據(jù)也,因其理甚玄妙,超于跡象之外,非常識所能索解也。夫《內經(jīng)》之靈樞,原名《針經(jīng)》,故欲究十二經(jīng)之奧妙,非精針灸者不能得其實際。愚于針灸非敢言精,而嘗與友人盧××(遼陽人最精針灸得之祖?zhèn)?談及此事,盧××謂斯可即余針愈疔毒之案以征明之。庚申八月間,族妹左手少陽經(jīng)關沖穴生疔,至二日疼甚,為刺耳門二穴立愈。關沖為手少陽經(jīng)之所起,耳門為手少陽經(jīng)之所止也。又辛酉七月中,族中男孫七歲,在右足太陰經(jīng)隱白穴生疔,三日腫至膝下,疼甚劇,取右三陰交及公孫二穴刺之,立愈。隱白穴為足太陰經(jīng)之所起,公孫三陰交為足太陰經(jīng)之所歷也。設若刺其處仍不愈者,刺太陰經(jīng)止處之大包穴,亦無不愈矣。又于辛酉八月間,本村田姓婦在手陽明二間穴生疔,腫過手腕,為刺曲池、迎香二穴,當時疼立止,不日即消。二間雖非陽明經(jīng)起之處,距經(jīng)起處之商陽穴不過二寸,曲池則經(jīng)歷之處,迎香則經(jīng)止之處也。又于九月中,學生吳××在手太陰經(jīng)太淵穴生疔,紅腫之線已至俠氣戶,木不知疼,惡心嘔吐,診其脈象洪緊,右寸尤甚,知系太陰之毒火所發(fā),為刺本經(jīng)尺澤、中府及肺俞,患處覺疼,惡心嘔吐立止,紅線亦立回,半日全愈。太淵距本經(jīng)起處之少商穴不過三寸強,中府則本經(jīng)之所起也,尺澤則本經(jīng)之所歷也,肺俞則本經(jīng)之所注也。由是觀之,疔生于經(jīng)之起處,刺經(jīng)之止處;生于經(jīng)之止處,刺經(jīng)之起處,皆可隨手奏效。則經(jīng)之起處與止處非有一氣貫通之妙,何以神效如是哉?
