大家好,我是青阳子,学习八字五年。

易经入门基础,说到底就是弄懂两件事:卦是怎么画出来的,以及卦象能用来做什么。很多人一翻开《易经》就被那些横线、卦名绕晕,其实只要抓住阴阳这条线,后面就顺了。

阴阳是画卦的根子

古人看世界,先分阴阳。白天为阳,黑夜为阴;天为阳,地为阴。阳用一条长横「—」表示,叫阳爻;阴用两条短横「--」表示,叫阴爻。爻就是组成卦的基本单位,读作yáo。

《易传》里讲「一阴一阳之谓道」,意思是说,阴阳的交替变化就是天地运行的道理。这句话不是玄谈,它直接决定了卦怎么画:三个爻叠起来,就是一个基本卦。

三个阳爻叠成乾卦,三个阴爻叠成坤卦。阴阳交错,就生出另外六个别卦。这八个三爻卦,叫「八卦」,也叫「经卦」。

八卦的名字和取象

八卦各有名字,也各有对应的自然物象。记不住名字没关系,先记象,再对名。

  • 乾:三阳爻,象天,性刚健。
  • 坤:三阴爻,象地,性柔顺。
  • 震:下阳上二阴,象雷,性动。
  • 巽:下阴上二阳,象风,性入。
  • 坎:中阳上下阴,象水,性陷。
  • 离:中阴上下阳,象火,性丽。
  • 艮:上阳下二阴,象山,性止。
  • 兑:上阴下二阳,象泽,性悦。

古人编了个口诀帮人记:「乾三连,坤六断,震仰盂,艮覆碗,离中虚,坎中满,兑上缺,巽下断。」这口诀念顺了,八卦的形状就印在脑子里了。

六十四卦怎么来的

八个经卦两两相叠,上卦加下卦,就得到六十四个六爻卦。比如上乾下乾,还是乾卦;上坤下乾,就是泰卦。

《系辞》说:「八卦成列,象在其中矣;因而重之,爻在其中矣。」意思是,八卦排定,物象就含在里面;再把八卦重叠,六爻的变化就出来了。

六爻卦从下往上数,初爻在最下,上爻在最上。读卦时,先看上下两个经卦的关系,再看每一爻的阴阳位置。这一步是易经入门基础里最实在的功夫。

举个例子。某人问事业,得「地天泰」卦,上坤下乾。乾为天、为健,坤为地、为顺。天在下、地在上,看似颠倒,实则天地之气交合,所以泰卦主通泰。但具体到某一爻,还要看爻位当不当。

卦象能用来做什么

传统命理认为,卦象不是用来断死吉凶的,而是帮人看清当下处境和变化趋势。古人说「善易者不卜」,不是不占,是不执着于占。

  • 看阴阳消长:哪一方在长,哪一方在消,心里先有数。
  • 看上下卦关系:上卦为外、为表,下卦为内、为里。
  • 看动爻:哪一爻在变,变化的关键就在哪一爻。

比如「水火既济」卦,上坎下离,水在火上,看似相克,实则各得其位,主事情已成。但既济之后紧跟着「火水未济」,说明成了之后还有未成之事。这种循环观,是学易要慢慢体会的。

入门该从哪里下手

学易经入门基础,不必一上来就啃六十四卦的卦辞爻辞。先做三件事:

  1. 把八卦的符号和取象背熟,做到看见符号就知道是哪一卦。
  2. 学会画六爻卦,从下往上,分清上下经卦。
  3. 找几个简单的卦,试着用阴阳、上下、动爻去读,不求断准,只求读懂结构。

《子平真诠》里讲八字重格局,学卦也一样,先看整体结构,再抠细节。卦象和八字不是一回事,但「先看全局,再论局部」的思路是相通的。

至于更深的纳甲、爻辰、卦气这些内容,需要结合具体命例反复推演,不是一两篇文章能说透的。这个方面还需要更多研究,读者可以进一步了解。
