quantum physics tells us:

[genep]

Quantum Physics tells us that physics and life is fiction. Reality's fiction.
It tells us the exact same story as did the study of thoughts "the Supreme Science" told the Indus River sages over 5000 years ago: the observer is the observations.
Take physics for anything more than fiction and you are on a wild goose chase to expand the universe just as fast as the thoughts that expand it to create it.
Accept that life and physics is fiction, just thoughts, and literally everything adds up PERFECTLY -- far far beyond our wildest dreams -- to the Unified Field: the timeless NOW, Samadhi, Atman, Nirvana.

I don't think it means reality is fiction - it's just not real in the way it's percieved to be real.  If you were to see things as they really are, you would see it's not reality that is the illusion, it's your perception of reality.

I think (for me, of course) that is demonstrates that physical reality is completely relative, that since everything changes and needs to be perceived ( for example: there isn't a 'point' in space unless someone assigns it) then it means that reality is changeable, therefore 'Not Ultimate'.  So the Atman, would be primordial, unchanging, and there is nothing  in reality that is primordial, unchanging, therefore it depends where you assign your reality: In the primordial, where your changing physical self doesn't exist, or in the relative, physical reality, in which your primordial self doesn't appear to exist.

I'm sorry if this is hard to understand- I've had very little sleep and am not very articulate at the moment.
