Scientists are now able to tease out how the 100 billion neurons and their interconnections in the brain create a world for you. Dr. Henry Markram "uses complex models to precisely simulate the human brain top layers in 3D..... it has been edging up on some deep, contentious philosophical questions about the mind ." You can have a peek at his work in the TED video at: Henry Markram: A brain in a supercomputer | TED Talk
Advaita philosophy tells in unequivocal terms that the perceived world is an illusion. The world we create is nothing more than a thought. It is merely a "castle in the air." We build the castle because of the force of our past impressions – the Vedantic term is vasanas. We trap ourselves in that bubble of a castle, our own creation. And being caught up in the imaginary world of ours is described as "bondage." You cannot even destroy this world because you cannot physically hammer to pieces a purely imaginary construction which is not really there. "Freedom" or "Moksha" is to jump out of it and just “Be.” Will modern neuroscience take us nearer to the Truth that advaita has been telling us for millennia of years?
