I see the brain as 3 different organs. huh?
First brain is every part of the brain excluding the Limbic system.
The second part of the brain is the limbic system, spinal cord. and your Sympathetic and Parasympathetic system. Flight Fright Fight System.
The third part of the brain is the celiac plexis. That is a collection of nerves in the gut and i believe it is what the Chinese call Qi (Chi). Core. From where you are supposed to breathe. Think of your body like a tree. The trunk is the Qi. it’s where your strength lies. Do the daily program every day and breathe to balance your Qi.
