仲景六經(jīng)之法．一經(jīng)有一經(jīng)之證．先要分看．分看宜在有字句處精研．而或此經(jīng)雜彼經(jīng)之癥．又要合看．合看全在無字句處善悟．而尤要在于辨似．有陽中之陰．有陰中之陽．有陽中之陽．有陰中之陰．有陽證似陰．有陰證似陽．有陽證轉(zhuǎn)陰．有陰證轉(zhuǎn)陽．有陽證雜陰．有陰證雜陽．有陰陽錯雜非細(xì)心體認(rèn)．惡能窺其萬一．今人輒畏仲景書難讀．而從事于后世之方書．是猶涉海問津．從仲景傷寒入手．始覺甚難．久之則其易焉者至矣從后世方書入手．始覺甚易．久之則其難焉者至矣．總之凡病不外此六經(jīng)．能解仲景六經(jīng)辨證之法．可以識傷寒．即推此六經(jīng)辨證之法．可以識萬病．傷寒既了然無遺．于雜證乎何有．此一以貫之之道也．故曰萬病莫逃乎傷寒．
