In our studies of Buddhism and meditation, there's emphasis on stilling the mind, or understanding the nature of the thoughts that race through our mind. We talk also of 'being mindful', that is, awareness of everything around us, influencing us.
Where is the mind? I tend to think it's in our consciousness. It's in our brain, of course, but not in the part that's an extension of the central nervous system. It's in the brain that's active when we are making sense of our surroundings, making choices based on past experience or making decisions based on emotional state. That's our conscious mind.
Philosophers and scientists have tried to define and discover the nature of consciousness. I don't think that a universally accepted model has yet been found. Personally, I tend to come at the question from a scientific point of view. That may not be the best approach, because it excludes alternative mystical or spiritual angles.
A leading theoretical physicist, Dr Roger Penrose, has been looking at the question "What is Consciousness" for more than fifteen years, and his ideas are based on quantum theory. Within cells in the brain there are microtubules of tubulin protein. These contain electrons that can become entangled with each other. The theory goes on to suggest that microtubules in other cells can be affected, and that multiple brain cells can form a coherent whole, with quantum effects being responsible for that coherence.
The work of Penrose is by no means widely accepted. It may be partly right, but waiting for someone else to add some important refinement before it becomes digestible to some others working in the same field of research.
I would like to think that he's on the right lines by bringing quantum physics into the explanation. It's known and accepted that quantum effects can be detected over a distance. I think about 150 meters is the most that's been reliably measured. If that is so, I would like to think that it could lead to an understanding of telepathy or remote viewing, by the transmission of quantum effects from one brain to another. That would be an example of the transmission of consciousness from one being to another, over distance.
It would also provide a basis for communication between animals and humans. At present, humans who practise it say it's like sending thought-pictures to the animals and seeing what images the animals provide back to the humans.
I'm digressing. What I am saying is that there's no good theory of consciousness at present. It's time there was one. We suppress consciousness when we are asleep, and we turn off consciousness when administering an anaesthetic. The next step must be to see where and how the changes occur between those two states, conscious and unconscious.
A reliable theory of consciousness could lead us to a better understanding of the mind, and eventually lead to improvements in meditation.
