After listening to the Jill Bolte Taylor video I came to the conclusion that she is kinda crazy, but she does have a point when the language portion of your brain fails you reach this level of nirvana because your liner portion also fails so you don't think about the yesterdays or the tomorrows you only think about right here right now. With the lost of language you also lose your inner thought or that little voice in your head. or the way Jill Taylor puts it "But perhaps most important, it's that little voice that says to me, I am, I am." When that happen you become a single individual and separate being from all those around you, and when that inner voice is lost you meld with the world, and the energy around you becoming one sentient being.
We are a perfect example of yin and yang, our minds are two minds molded into one working in perfect unity but, when one fails we are left with only half of are self. If we choose our right side we become all, together, one energy flow, if we choose out left side then we become singular, I am here, I am.
