Duality provides another rigid structure for 3D experience. Up/down. Left/right. Should/shouldn’t. Since the fall of Atlantis 12,500 years ago, we have become very fearful as a way of life, and in that fear we have learned to narrowly define good and bad, right and wrong, etc. Unconscious judgment permeates 3D thinking.
Moreover, we perceive our 3D experience predominantly with the left hemisphere of the brain, home of the rational mind, and so we use only about 5 to 10 percent of the brain’s capacity to play the 3D game. Most of us suspect the rest of our brain must do something but have no idea what it actually does and how it functions.
In fact, what the rest of the brain enables us to do is function in the higher 4th and 5th dimensions, and beyond.
