Although we
are not all in physical pain or mental anguish all the time, we do exist primarily
in a state of being ill at ease in the world, of being alienated, “made other.”
There are two sides of the brain. The left brain processes data in a differential way, while the right brain processes data in an integral way. Like in calculus, differentiation defines the slope at a point on a curve, while integration, defines the area under the curve from A to B.
The above statement is an artifact of the modern conscious mind being mostly conscious within the left brain. The right brain still works but is more unconscious. This situation will create conscious perception of being different and unique; we see ourselves as a unique slope at a point on the curve called humanity.
If the conscious mind was more centered in the right brain, one would feel they are a part of a larger integration.
Based on what we know, one could infer, that the pre-humans, defined as the more natural humanoids before civilization, where more right brained. They could not yet differentiate reality for the needs of civilization, but were still integrated with nature and instincts via right brain. As the brain gained energy (divine spark) and consciousness migrated toward the left brain, consciousness begins to see itself as separated and isolated, due to the way the left side of the brain processes data. The integration with instinct becomes less conscious and this begins to change.
In Judeo-Christian symbols the tree of knowledge of good and evil is left brained. This symbol is about the conscious migration. Law will help differentiate behavior, but it does not integrate the individual within themselves. Rather it attempts to integrate one outside themselves, via culture. The alienation remains since this is an internal feeling.
The tree of life is more right brained and integrated one within themselves. One feels internally and externally integrated, but not based on the differential of a culture but via the integration within the right brain. The next step in human evolution will be migration back to the right brain while retaining access to the left brain. This takes more brain energy. Theoretically, it brings the internal integration to the differential side of the brain, defining culture in ways that allows the feeling of alienation to disappear; paradise.
