The Bio-electromagnet inside you head
The human condition comprises of two states of being. One is the physical state. This is the material body that emerges out of a Darwinian struggle and repeated adaptations to become what it is today. This state is created out of blueprints stored in the DNA of our chromosomes and provides the ‘recipe’ for what the physical body contains. By physical one is referring to, in addition to the visible physical body, blood, tears, urine, lymph, bile, hormones, neurotransmitters and neuromodulators, vitamins and minerals, nerves and brain, the air in our lungs – oxygen and carbon-dioxide, etc. In other words, everything that has physical ‘presence’ and can be observed, analysed, measured and categorised.
The other state is consciousness. This used to be known as mind, spirit or soul in previous times. Some say that this refers to an emergent property of the interactions between the physical constituents of the material body. However, this state is non-material. Whilst one can map changes in EEG (electrical activity of the brain) fMRI (flow and volume of blood utilised by various components of the brain and the rest of the body), PET (indicates use of glucose as a source of energy in various parts of the brain and the body), GSR (measures the changes in electrostatic energy across our fingertips), etc., there is no way of observing consciousness directly much as one would observe other aspects of the body and the brain with its constituents. Consciousness remains hidden. What emerges on the various electrical and electro-magnetic activity-mapping tools is just that – evidence that certain parts of the human brain is active; more active than other parts and that this activity moves around from each thought to another, each feeling to another and each movement to another.
The question is whether this is all there is to consciousness or whether what we observe is just parallelism, i.e. its merely an analog to what happens in our minds. Much like the dashboard of your car which reads out a lot of information that guides you in your use and maintenance of your car. The dashboard readouts are however not the real thing under the bonnet and underneath the car. The fuel readout for example is not fuel itself, the speed readout is not equal to the sense of movement at a particular velocity. The distance covered is not equal to the topography of the land you have come through. But what one does know is that it is powerful - much as magnetism is although you cannot trap it into a jar, visualise it, or even touch it. You can feel its power and you can measure it. Consciousness is that. A powerful field inside our minds that generates all that we think, sense, intuit, feel, intellectualise, intend, create, inspire, emote, act, behave, comprehend and express. And its all bio-electromagnetism!!
The bigger quesion is not what it is but what its contents are.

"Consider yourself. I want you to imagine a scene from your childhood. Pick something evocative... Something you can remember clearly, something you can see, feel, maybe even smell, as if you were really there. After all, you really were there at the time, weren't you? How else would you remember it? But here is the bombshell: you WEREN'T there. Not a single atom that is in your body today was there when that event took place. Every bit of you has been replaced many times over... The point is that you are like a cloud: something that persists over long periods, whilse simultaneously being in flux. Matter flows from place to place and momentarily comes together to be you. Whatever you are, therefore, you are not the stuff of which you are made."
