So you are saying that, when someone makes the decision to meditate, it is the brain that is actually making that decision, and that the changes that occur to the brain, respiratory system, heart rate, pain, digestion, etc. are also controlled by the brain. If that is the case, why does the brain need consciousness in the form of a self to make that decision, or any decision? Does the brain decide to go biking, or have a martini after work, or go have a pizza on the spur of the moment? How does the brain learn to lie, or crack a joke, or create a scenario to put the make on a woman or a man, and then to top it all off, to sit back and reflect on all those decisions or experiences once it decides to go ahead with them? All via chemicals and electricity? Is it all electro-chemical when the brain decides to become a murderer or a nun? What determines that difference? The brain creates a persona and then creates scenarios for that persona to follow? If that is the case, then every brain is different, as each human is different.
Sorry, I don't buy it.
My brain does not control who I am. When I make the decision to strive for higher spiritual ground, that is to say, greater joy in my life, it is not the brain doing that. There's some other presence in my life that is subtlety prompting me to do so, and I know for certain it is not the brain. I do not experience consciousness only in my cranial area; I experience it throughout my body in different centers. These are called chakras, the most prominent ones being the heart chakra and the hara, just below the navel, unmistakable centers of conscious awareness. In fact, in the East, the center of consciousness is NOT in the cranium, but in the hara. It is the hara that is closely watched in martial arts to determine the next move the opponent will make. When I focus on the hara, there is a powerful sense of peace and balance that develops. There is something alive and conscious in the hara, nothing like the experience in my head. It is not intellectual at all, and feels like the seat of power, but not in the egotistic sense at all, but just power that is conscious, and that knows far more than my mind can possibly know, as if it is always far ahead of what the brain can come up with.
If it is the brain making the decision to gain higher ground, then why does it not just do that and stay in that state? Why is its default state that of ordinary life, with all its pitfalls and misery? If what you say is true, then the brain is a faulty piece of hardware, as the history of the world is testament to, the brain having made all those horrible decisions for war and greed.
