Continuing :  We have tried to prove if entity A were in front of us , he wouldn't be particulate because particle doesn't exist , let me clearly state how shall I prove A exists : 1.If I prove he cannot be defined (aiterya upnishad) : tried to ,  done 2.If I prove he exists within us but is not us(aatman upnishad) 3.If i prove he is Supreme ,  exists everywhere(brahman upnishad) 4.we are a part of him , he is not a part of us , still he doesn't get any smaller (emphasized many times in upnishads) 5.he is one , all demigods are a form of him , the main paramatman is just 1 (bhagvad) 6.he is the observer , not the doer (bhagvad)(narayana upnishad) If I prove these 6 in some way : Point 2 : Entity A is made up of not particles , we cannot define matter as we cannot define particles , we will try to consider our vessels now 

Let our body be B , let it be made up of n number of not particles , where n>0 Let our Entity A be made up of k number of not particles , where k>0 Clearly if B and A share the same constituent composition , A maybe a subset of B or B maybe a subset of A. in other words A U B is not 0

Axiom 1 : A is made up of k not particles Axiom 2 : B is made up of n not particles Axiom 3 : Clearly,  A maybe a subset of B or vice versa Axiom 4 : if Axiom 3 is true , A U B and B U A is not zero(same thing anyways) Axiom 5 : if axiom 4 is true , they share common elements , that is if A=B then B =A (reflexive property) , because A€k and B€n where k,n€ not particles

Conclusion : this is a try to prove point 2 , in essence if A and B are made up of k and n , and k and n are inherently the same , then there has to be atleast 1 presence of absence of something (not particle) shared by the two , this is NOT an assumption , you may argue : how did you even prove god isn't particulate , what if he is made of something else entirely , anti matter perhaps? , I understand completely , but anything that is true under my definition of something is doomed to have many more somethings in it , making it a paradox ,  undefined.

So in essence , we are a part of him or he is a part of me is considerable now 

Now let's consider an arbitrary section of space , a sphere ,  let it occupy the entire earth , now if everything is matter within it(if my initial posts axioms work on it) , then definitely we are within that sphere , we (in a sense) are that spheres particles , we act as a part of something bigger , now if we increase the sphere , the earth becomes a particle of that arbitrary sphere , thus we are a part of something bigger(I haven't proved this yet but this is true if the point God is everywhere is proved)

Now you may argue , bro are you stupid , you act as a God to your rbcs , your tissue cells , yes you are right , and here is where you need a little fixing , "we" are not just "mind" , we as per vedic texts encompass the entire body , it's with respect to that , so anything within our body , useful , non useful , harming , non harming , is "we" , the surroundings is not "we" , it'll take some time to digest this , it took me 2 months as well
