When we were discussing TMAHE in our Reading Workshop, I found this concise summary of the hemisphere differences as explicated by McGilchrist from this website very useful:

It is also really interesting to read what Laura wrote about the hemisphere differences in relation to desire, intent and anticipation in The Wave Chapter 23 (bold emphases mine):

The Wave Ch 23 said:Q: (L) Okay, so this realm changed, as a part of the cycle various choices were made: the human race went through the door after the gold, so to speak, and became aligned with the fourth density STS faction after the right-brain/female energy consorted with the wrong side, so to speak. This resulted in a number of effects: the breaking up of the DNA, the burning off of the first ten factors of DNA, the separation of the hemispheres of the brain…
Q: (L) What was the motivating factor for playing in the dirt? What essential thing occurred? You said once that it was “desire-based imbalance”. What was it a desire for?
A: Increased physicality.

Many scientists have studied the effects of head and brain injuries. The results have led to theories about two different modes of thinking or styles of thought, which are generally attributed to the left and right hemispheres of the brain. I think that we may find some clues in the comparison of the legend of Orion to the stories of King Arthur and the Quest for the Holy Grail. What does Orion have to do with the Grail Quest? A great deal, I think. The similarities between the stories of Orion and Arthur, in essential terms, are many. [...]
The story of the Grail is the story of the creative potential of the human race in very real, though esoteric terms — the power to re-create the Golden Age — a pathway to knowledge of an ancient technology that gave rise to the great megalithic monuments for which no rational explanation exists — a power that has been hidden from us for ages past. In discovering the true Grail we may also find the source of the Control System that has operated on our planet for the past many thousands of years, keeping humankind in bondage to time, history, misery, decay and suffering.
We note above that the left brain rules by conceptualization, imagination, and dogma. We then note that the right brain rules by sensing, perceiving directly via observation. When the story says that Orion raped his love, the meaning is clear: the left-brain took over the function of the right brain, which was the direct conduit to universal powers of creation within the individual. Eve consorted with the wrong side.
What [religion] is doing is developing mental boundaries. They are creating an image of the world in the left hemisphere mode of thinking. It is fixed, limited, and most of all, prevents discovery, change and spiritual evolution. Worse than that, it blocks creativity in a cosmic sense; it is the desire to possess knowledge in a limited form; to own what cannot be owned and place limits on something that is in reality infinite. What is wrong with wanting a return to God, or higher consciousness or any of the touted experiences that are guaranteed to initiate a person to whatever they desire?
The problem is anticipation. When you seek any of these things by holding the thoughts in the left-brain in anticipation of making it real, you are raping the maiden of the well. What if you are just trying to believe it is now? Belief is a function of the left brain; it blocks the manifestation of creativity because the creative right brain is also the empirical half of the brain that observes the dichotomy between the belief and the reality. Desire is anticipation. Anticipation is read by the right brain as in the future, therefore not right now, and the right brain can only create now. When we desire, we have a future object in mind. The right brain only knows now.[/url]
