There is a school of thought that claims individual consciousness does not emanate from the human brain. It believes, instead, that brains merely act as receivers for consciousnesses residing elsewhere, somewhere "out in the ether" as old-time folks used to say.
So I suppose you can imagine your brain as some sort of transistor radio, or perhaps even a ghetto-blaster depending on the size of your skull.
If this school of thought is correct, and my radio analogy appropriate, then our individual understandings of reality are obviously predicated upon the particular consciousness station on the subjectivity dial to which our brains are tuned: Voice of Atheism, Jesus World Service, Commercial-Free Buddha Cafe, Islam Talk-24, or just static for some sorry souls.
Are you a short-wave conscious, a long wave conscious, an FM or AM conscious? How strong is the signal? How easy or difficult is it to change the consciousness broadcast you're receiving? And more importantly, if our consciousnesses do not abide in our heads, then where do their transmissions come from?
Are they just random entities floating around in the atmosphere like mobile disc jockeys spinning their favorite Akashic records? Or are they cosmic beings seeking experiences in the material world that only flesh and blood incarnations can provide?
Alas, I doubt we shall discover the truth until it's time for each of us to trade in our corporeal consciousness receivers for newer models, if, indeed, such an exchange scheme exists.
