I know, but but the fact that reality isn't accesible without intermediates, doesn't mean that is not accesible at all, or that "nothing is real". Of course we can't directly observe atoms, but indirectly we can know how they behave, and in their behavior we can imagine it's properties. Otherwise we wouldn't know that they are mostly void, like you said. The fact that reality seems solid to us has no relevance to the fact that matter is mostly void. We can understand that "experience" and "matter" are two different components of reality, because we relate to reality in some way. The fact that matter and experience are different instances of reality doesnt mean they are mutually exclusive, it's when they happen TOGETHER that reality emerges. It would be of no use to disregard everything as "unreal" just because we can't directly access reality and everything we know appears to us veiled through our senses and our rationality. Our experience of matter - and spirit - IS what makes reality happen, so instead of saying "ALL IS NOTHING, EXPERIENCE IS FLAWED SO THERE IS NO COMMON GROUND, THE ONLY TRUTH IS BEYOND THIS WORLD" i would rather take care of my own experience of this world and the way other people experience it, and do my best to build a meaningful world in THIS earth, that you call an illusion, that you call vacuity, that you call a deception of our senses and a lie.
If everything were an illusion, then why call it illusion? Concepts can only be defined by it's boundaries, that's why absolutes are impossible. For an objectivity to become "positive", it must be surrounded by it's own negation.
I would combine the two! I do believe all this is illusion with no agreed commonality beyond the basics and even that is up to interpretation. That said there is enough of 'agreed' reality to navigate this existence and have a meaningful experience it is just that that experience is rooted in illusion and as such can only be a shadow of its true form. I have no idea whether or not there is a 'beyond this world' so tend to operate under the belief that what I see is what I get and I work with that within my current understanding.
