理解知行合一有四重境界：

第一重知：知道,；行：做。

知道了才能做,，不知道就不曉得怎樣做,。

第二重知：知道；行：去做,。

知道了,，才會去做，不知道就不會去做。

第三重知行互輔

即如“學(xué)而不思則罔,，思而不學(xué)則殆”之意,，知道了再去做，做了會更知道下次該如何去做,。

第四重知行是同一個意思，而不是兩個階段

沒有先知后行，也沒有先行而后知,。任何事情都沒有分成知和行兩個環(huán)節(jié),，不（去）做，任何知道（包括學(xué)習(xí)）都是不知,。道理講的天花亂墜，就是沒有成果出來,，還是不知，正如很多專家教你如何炒股賺錢,，其實還是不知,，因為他們沒有做出來，也即如王陽明的學(xué)人中少有人能修的大果,，即便傳習(xí)錄背誦的再熟,，也是不知。

做了,，即知了；知了也是做了,。如果因為做了有新思考,，導(dǎo)致下次做更有效，那又是一次新的知行體驗,。

注：之所以很多書上把知行單獨分開論述，是因為得大成者通曉普通人的心理,，分成兩個階梯更容易讓人接受并見效,，一步登天的天分不是常人都能有的,。

There are four steps to know ‘knowledge and action are one’:

First, knowledge meaning know; action meaning do

You could do one thing after you know how to do it.

Second, knowledge meaning know; action meaning to do

You do one thing as you know how to do it, if you don’t know, you will not to do that.

Third, knowledge and action is helpful for each other

You do as you know how to do, and you will know how to do next as you did last time.

Fourth, knowledge and action are one, not two parts of one thing

Know and act should be one thing in one action when you do something, if you not to do, you must not know, as most professors teach you how to earn money by investing in stocks, you should not believe them, if they could succeed as they said there will be not any one to teach you as a honest teacher. Also as students of Yangming, no one reached his level after Yangming.

Only to do, you will know the real truth, and you will know how to do better next time, another knowledge and action are one feeling.

Ps: there is so many sage also said knowledge and action separately, as they know ordinary people could accept it easily, the guys could know the sages meaning directly is so few.
