I see you are still using a quote from me in your sig where I state, "I know my brain cannot tell me what to think"
A lifetime of fighting for my sanity against the processes of schizophrenia, most of the time without medication, tells me this is true. I am the thinker, not my brain, and chemical chaos in my brain cannot make me less than my own master.
As far as I am concerned that is because thought is free, and not controlled by our brain chemistry. The reason for that is we are a spirit linked to the brain by the etheric body.
