I really struggle to follow your reasoning sometimes... :P
I know, you're not alone. Many people have said this but it's actually good for you. It gives you something to get your head round :)
Probably the trouble is that what I'm saying is very simple, it's not terribly intellectually difficult or technical. Most of the time it's simply the obvious and for some reason it seems to elude us.
Let's do it again. It'll be longer because I'll have to explain everything.
Can you prove then, that it is possible that there is some existence without knowledge?
First, what do you mean by prove? Either you mean with reasoning and argument like philosophers do, or using equations, symbols, and all that. Or you mean actually experiencing, discovering for yourself that there's something beyond the mind.
I only do the last one. I can't do the first one, it has no meaning for me; I wouldn't know where to start. Also I don't believe that reasoning alone is actual proof of anything because it would have to be verified by experience anyway.
Then what do you mean by existence? I don't think you mean physical existence or aliens etc. I think you just mean is there anything, any state, outside what we call the mind.
Then, what is the mind? This is more complex.
What we normally call the mind is our thinking process, right? We use the mind to calculate a maths problem, work out a shopping list, and so on. It's a process of thought.
In that area are not only the everyday practical things but also our psyche, our dreams, our desires, all the psychological issues and problems. We actually live in our minds. Our thoughts are there, our actions come from there.
Now that area is actually quite small, isn't it? Each one lives in their own 'bubble' as it were. They have their own knowledge, experience, thoughts. It's not an unlimited space, it's very limited. We only know what we've read or experienced ourselves and it's circumscribed, it has definite limits.
We can't think beyond what we know. You know your phone number, for example, but if I asked you what mine is you'd just go blank - and that's just phone numbers. So there's lots and lots we don't know and we don't even know we don't know it.
HOW is it possible that, through your mind, you can prove the existence of something outside of it?
Now you're asking if there's anything beyond that. I think that's your question.
First, if any area is circumscribed there has to be something outside it. A circle has a circumference, a perimeter, a boundary. The boundary is only possible because
it exists in a wider area. Isn't that clear? Life or existence is immense, it's not just the little psychological world that we live in.
You're asking whether it's possible to prove that there's something outside and whether it's possible to do that without some kind of knowledge.
If you only mean theoretically, using knowledge of philosophy, logic, and so on, then the answer is yes, it would be necessary. But have you actually proved anything? One can only surmise, come to some kind of conclusion based on reason. It would still have to verified, wouldn't it?
If we start theoretically we end theoretically so we haven't moved away from the area of the mind as knowledge and thought. We're where we started, still in that limited area. So, through knowledge and thought we can't go beyond knowledge and thought. That's clear too, I think.
Now is that all there is to the mind? Please follow this carefully!
As long as the mind is occupied, moving, its space is limited. The very activity defines its limitation. The activity is
the limitation! If that activity stops there's silence and that silence has no border, it's limitless. Then the mind is itself the limitless.
That's how you do it.
