We are taught that brain function must be this way, the dance between left and right brain. In the traditional yogic sciences, the brain and mind are trained to move in to more symmetry, more harmony. Then, at some point, a new processs begins. For some, it takes quite awhile. For others it is instantaneous.
Then, the brain works as the hologram it is designed to be, with both hemispheres firing simultaneously. Brain f unction moves from deep in the brain center to both hemispheres at once, and the side-to-side movement is actually quite disturbing to the body when it tries to replicate old patterns. When this began for me, I used to become nauseous and dizy when my brain tried to move in the old way.
If we move to center, and allow Source to do the navigating, the change takes care of itself.
I have written about this experience many times with regard to my stroke and what happened physically to reset what was already occurring energetically. I do not know how to make a story of it just now. Désolée.
I can say that my brain no longer works in the old way and my mind has learned to adapt. Merci.
