As evolution shaped our current form, various parts came together to make a functional whole. While one can be alive without certain bits in our bodies, it usually takes all of our organs to live. The question often arises whether we are our bodies or brain because there is a certain degree of redundancy in our organs while the brain is irreplaceable (mostly). But the brain is also an organ like the others so what makes it special? It is said that it processes external stimuli and converts them into perception, perspective, emotions, reactions and a plethora of responses. But what if this is done by all the organs in tandem with the brain? The stimuli and resultant reactions are all a function of energy, be it mechanical, chemical or electric. This makes me believe that we are neither the brain nor the body, but we are energy. The manifestation of the summative energies is us. Energy cannot be bracketed in any categories, like positive or negative alone. These categories are relative to the person describing them. And for the same reason no one is entirely one type of person, the various energies that are changing within them at that time make them the person they are at that moment. As the law of conservation of energy states, energy can neither be created nor destroyed, but only changes from one form to another. I think we are a sum total of the various forms of energy that are manifested at that moment in time and space. The body and the brain are matter by themselves. Unless animated by energy they are just matter. So our brain is our body and our mind is what makes us human. The brain is a thing while the mind is abstract. It is energy.
