Brain in a jar and the kaleidoscopic universe

It occurs to me that since our brain creates a picture of reality based upon electrical impulses from our senses then who is to say that we are not just brains in a jar in some laboratory floating in some nutritive solution and hooked up to electrodes feeding us impulses from some sophisticated computer?

I assume that I have a body but I only seem to experience it based on sensory input. Similarly, I assume that the people and places I perceive are also so real but are they anymore real then the people and places I experience in my dream? Certainly there seems to be more consistency and longevity to 'waking state reality' but does prove anything in itself?

Following on from the previous posting there is a sense of a personal me which assumes it is responsible for my life, my choices and my actions but is this anything more than some kind of perceptual illusion?

Maybe I am not a brain in a jar but maybe the brain itself is part of the illusion and the programmer is some kind of superconscious nonmaterial intelligence playing its own game.

The Sages tell us that all manifestation has its source in one Unified Consciousness which has created this drama and has individuated itself into billions of seemingly separate conscious entities. To experience itself evolving in awareness and eventually reaching the point of awakening from the hypnosis of separate individual doership to the reality of the one Unified Consciousness again.

Consciousness awakening to Consciousness, and for what? Maybe just why not? Just the play and experience of diversity and the joy of reunion once again, time after time and each time unique.

About the kaleidoscopic universe; if it's all just a play and perhaps there have been an infinity of universes coming into being (successive Big Bangs) and imploding back to the source again then perhaps 'In the Beginning', 'God' shakes up the energetic elements and parameters which govern the unfolding of each universe, rather like a kaleidoscope, and then each creation manifests its own unique beauty and symmetry according to multidimensional inter-related cycles within cycles. It may get ugly at times but presumably everything balances out in the end.

From the individual point of view? Might as well adjust to the uncertainty of life, realise that it's not personal and enjoy the ride; if one has the good fortune for that possibility.
