Since our invention of words, we have given priority to beliefs in words instead of our direct experience.To invent the first word, such as "river" for a river, it was necessary to invent the assumption the universe is separate parts. Only then could we invent a sound and symbol for a river that was different from the sound and symbol for every other object, such as "tree" for a tree and "rock" for a rock. As you will see when you answer the 7 questions at the beginning of this book, it is obvious in plain sight the universe operates as an indivisible whole, the most fundamental fact in physics. It was not necessary to be aware we unconsciously (without choice) invented the assumption the universe is separate parts when we invented words. Not knowing we did this is our mutual blind spot. The evidence for it is most of us still think our accurate self-definition is "I am my physical body." This is not true. The accurate self-definition for each of us is "I am first the indivisible universe that will not die and secondly my physical body that will die." This makes it obvious there is something more important than our lives. It is described herein.Today, most people on Earth are unaware of this mutual blind spot. This makes it difficult to correct. However, we cannot master the last two of the seven layers of maturity of the skill of human self-consciousness until we do. You probably already know the first five. The last two are not difficult to master, and you will be guided into mastering them in this book.This will mature everything we do. We will learn how to have our marriages be a joy for our entire lives. We will elder our children to full maturity in this skill before they leave home and marry. We will create and give priority to our freely chosen agreement nations while still being responsible citizens of our geographic nations. We will mature capitalism into common good capitalism. The latter could also have China join the US and the rest of the world in it. This would end our movement toward a conflict between our two nuclear powers that, if led by immature people, could be horrendous. We will end poverty for the common good of all. We will end war by agreement. And we will manage our environment for the health and sustainability of life on Earth.It is 2019. Our discovery of this mutual blind spot reveals we are now overly ready to master the last two layers of maturity of the skill of human self-consciousness.
