I know that in many religions or in the work of many philosophers the ultimate truth or essence of existence is depicted monist. Some even argue further that all our experience is an illusion- which I could not agree more and that is backed by science as well. Again, science currently supports monist views on the origin of matter too.
However, does that really imply all of the illusions we experience are not tied to reality? Or does that have to be true that we "create" objects through our experience, which do not exist in the "absolute"? Do we have to reach "the Absolute" by reduction? Or even if we reach a monist essence we can describe the Absolute definitely?
To make the question, let me give an example:
This bottle in front of me is not a "bottle" if you use an instrument that can only detect baryons (reduction). The borders of it and its surrounding universe are of the same essence, which are made of atoms, and have no distinction (as we currently know of) in terms of essence. Here you see we reduced our object of its structure. However, their (the bottle and its surroundings) difference and its manifestation in my mind is caused by their organization and arrangement. Does this arrangement and organization have to be an illusion? Yes, everything is connected to each other and there are no distinction in terms of "essence" as we know of, but does knowing that essence makes us reach the absolute?
If we argue this in terms of the so-called "Absolute", isn't my experience of this illusion supposed to be a part of reality?
