In the change of the whole everything can be discerned by one another. So this whole change is what makes everything be what it is. Thus, it can be said to be a principle that penetrate everything. And this change enables everything to be distinguishable as it is, from behind the disctinction. so it can be said it is beyond every distinction. This is why the principle of the whole change cannot be a part of a knowledge. Now then, I wish you can understand the reason that an enlightened man only knows everything, whereas he can say nothing correctly.
Let me comment on the stress given on the necessity of mind and body. Since Descartes had said 'I think, so I exist", the tradition of western philosophy have been focussing only on the mind as consciousness. Then everything about physical body came to belong to mysterious riddle that we cannot be sure of its existence in spite of our evident daily experience with it. On this matter, I think we can solve this problem only when we move to another standpoint of philosophical reflection on mind and body. This is why I stress the necessity of mind and body, in the first sentence. of the text.
