To be or not to be...

Are we actually there or are we not?? Is the universe governed by materialism? Materialists say we are actually there i.e matter rules. According to them matter is eternal: it has been forever & will stay forever. But let us look into some very befuddling mysteries first.
First of all let go of all bias & emotion. The computer before which u are sitting is the computer u r seeing inside a dark place in ur head called the brain. Although no light ever reaches the brain, we are still able to see a brightly lit world. Consider a hypothetical situation…If the nerves which carry the vision impulses from ur eyes to the brain are suddenly severed, would u be able to see the computer??? I think not. Not just vision, all the senses are formed & processed in ur brain. The table u touch is a “table” as told to u by the brain. If the brain is somehow manipulated to process the table u are touching as say, a chair, u would say the table is a chair.
Consider another situation. This one is good material for science fiction movies. If the sensory nerves to ur brain are severed & replaced with (by exchanging) those of ur friend sitting home enjoying a movie, u wud be the one now watching the movie while ur friend stares at the boring computer screen. All ur thoughts & feelings will be correspondingly interchanged. U wud no longer be you, u wud be ur friend….
Take a long breath, I know this is not easy to digest but it is a fact nevertheless. You & ur surroundings are what ur brain tells u they are. Nothing less, nothing more. The consciousness of the brain surpasses the material aspect of things. I do not claim to understand every bit of the mysterious thing called the brain but I want to make people think & decide for themselves…
