By having both of these hemispheres work together inside of one head, we experience a natural duality.
It is normal for us to endure an ongoing internal conflict, based completely on the two uniquely autonomous perspectives of our left and right brains.
Our right and left brains would forever evolve on separate yet parallel tracks of consciousness and exist in duality. Our right brain would evolve to be the home of our feminine, yin, and grace of the cosmic right here, right now, while our left brain would develop masculine, yang, and ego-centered traits based on our individuality.
