Define 'IT'?
Firstly I'll post the original but updated version [1], then the second instalment [2]. if it is too many concepts to assimilate at once then scroll down and view part 2 and see what you make of it.
1.
What is the universal meaning of 'it'.
Everything is an 'it'. consider the absolute, the distinct, specific and universal meaning of the term ‘it’ – it must be everything in the singular, the multiple and the universal – the given thing 'IT' itself, the holistic object and the meaning. Then 'it' has all that we are, all aspects of nature & the universe generally, multiplied by everything else one can possibly think of and what we cannot.

IT. As amorphous and anti-amorphous.
Firstly lets include the notion of everythingness & Omniverse [all universes eternity and etc], ok so we don’t know if there are many universes or one, I use the term ‘omniverse’ as a way to envelope any future understanding of the nature of all universes. IT is the form and the unformed natures of reality, IT is the illusory, the real the false and the true – equally.
if you took an infinite reel of cotton and threaded it through all quantum existences and through time, space and dimension, then through all connecting parts of the 'grand machine' of the omniverse, what do we have? Another indefinable nature that is beyond and including existence itself! We can see this simply as 'the universal' or specifically the reality and nature of 'IT'.

The end of things? If you take the universe away like as if it came to an end, what is there? Infinity itself is relative to the states or definitions of finite/quantum & infinitesimal. The infinitive however may be seen as infinity in its incomparative nature, as infinity when nothing else is present. This state of statelessness is also an 'it' then in a grander scheme of things can be included as an entity alongside existence as if of its own dimension, yet is still attached - as all things are – by the string of the universal. Here then we may see an apparently dichotomous reality that includes this nirvana like 'infinitive' as somehow inherent to the universe; the very 'nothingness' from whence quantum energies arise! Equally so IT the infinitive is the centre of our being and an epicentre of all life, when distinct it is a 'you' or 'inner-self', when indistinct it is the essence of life universal, kind of like a universal spirit – if you will, whereby everything from vegetation, insects and animals to micro organisms and the collectives thereof all co-exist and emanate.

Defining 'IT'_II.

It = everything

there cannot be a lack of extension to this as there will always be an 'it' beyond that described.
Thence

it = more that everything

i,e, it can be that which is not a thing e.g. statelessness. thence 'everything' is extended to 'everything' as its naturalised idea of all natures, even that which is not a thing nor an entity.
Thus

as It = limitless, then
It = omni-entities and non-entities, where an entity can also be that which cannot be described as a thing or as something which has no discernible or actual defining qualities.

It = nothing x everything x omni-entities x non-entities

the void is a state of statelessness, 'it' must have this quality or we have placed a constraint on that which cannot be constrained. we may also say that 'it' must be it, which itslef has no definition thence is stateless.
It also can be infinity, yet this is a comparative description relative to the quality of finite, which is a false quality as nothing has a definable limit.

'It' is equally all 'it's'

if you can find a quality of god that is an 'it' or set of 'it's', then it [god] exists or does not exist yet is equally 'it'!!!

so the question is; if an 'it' that does not exist is equally an 'it' as to an 'it' that does exist, then all 'it's' are equal. Thence the state of existence may only describe a different kind of 'it' and is thus no more real than any other state of 'it'.

It = the string by which all things and non-things are joined x the entities themselves. If we – an entity – are joined to 'it' the all and the string, then...

god = the 'it' that is the all of what we and any other given entity are. and 'it' must have this nature! [weather we call it 'god' or not]

Thus

whatever 'you' are god is!

...but that doesn't mean he exist




...anymore than you do!
