Here, we should suppose our very original ancestors' daily life in usage of words as language activity.
as I explained at Part1, our bodily sensation as pain or ached fact is never seen to other ones except us as each myself, then its thing is never similar to seen things e.g. trees we can watch there, or the third person for us there we can look at. Then we can know other one's pain only after the one confesses us it, unless the one has done, we could never know that fact.
At this meaning, our ancesotrs in supposed situation as tribal society to engage them in hunting or collecting toward games or fruits or so, members of society must have had the method to tell own pain or bad conditioned bodily situation to upper status one, then "Ouch!" or precise informing having some part of their body as painful or ached was probably the most fundamental words for them, adjective, painful, or so would have been the most fundamental vocabulary. 

In oother words, just tellintg own pain to other members must have had been so integral manner to survive the social function in terms of mission to survive all members' life secured.

Then, we can say that all our mind's internally held things as intrinsic matter could be susutained with substential our acting and social activity , in other words, mind itself could never be composed without practiically working habitual acts and social dutiful action and that object. Mind could never be set nor composed only by itself.This thing is very vitally important premise.

By the way, we all are staying home very almost hours a day, and we are now never contacting many otueur general citizens, then we are facing very long conscious hours to be conscious about our body, then we get easily to be delicate the physically sensention at our own body. As its evidence, when we are busy at working, unless we are so bad bodily condition, we cab hardly feel our body sensation so particularly.
Otherwise, when we confront the very limited term un til the date for payment or the agreed date for bdelivery or so, we are apt to be anxious about doing it so well, then we can have the experience to nbe ached at some part of our own body or so.
In other words, our bodily pain or aching must be connected with our daily missioned things' proceeding condition. Then if we can have unsolved thing around no brain working, but only aching or pain is existing, that gapped thing is not so enigmatic. 

These analysis is just so down to earth analysis. 
Then, here we can judge that words of our informing of own thing as intrinsic bodily sensation must be impacted by many things in our life matter. Eventually only our pain or own body sensation could nnever be seen to other ones, then with that implicit very dundamental premise, we just tell some abnormal state of our body sansation  at our particular occasion, with that act, we can understand each distinct bodily sensation's presaence. That factual truth must tell us that eventually our personal thing as pain or so has no way but dealing with care to other one's physical condition. 
And that thing could be easily either apllied to emolional mind as emotion, feeling or anything. And these things are essentially black box to anybody, but we are usuallyevading that thing's indication, in other words, we implicitly intend never to mention that thing.
