When you point a camera at the world, it "sees" a unified field of view. In order to see a separate thing, such as a chair, the image of a chair would have to be created with a graphics generator and projected on a contrasting screen. This is why I tell people that a camera cannot take a picture of a chair; it can only capture the entire field of view. Most adults see the world through an imaginary grid that makes it appear to be composed of separate things. They do not see the world as it is; they see it as they imagine it to be. A camera sees "what is" whereas most adults think-see a surreal mixture of reality and ideas. All adults with an IQ above 90 realize that the words we use to represent the world are imaginary and arbitrary. Most adults DO NOT realize that all boundaries defining "things" are equally imaginary and arbitrary. That is the only point that seems to be relevant in a discussion about non-duality. How the brain initially organizes the sensory input in a newborn is another issue. By the time a child is a year old it sees the world as it is but without the imaginative overlay that will come later. It enjoys several years of substantially direct interaction with the world before it shifts from direct perception to imagination as a dominant mode of mind. Returning to a child-like state of being brings the same kind of joy and non-reflectiveness that anyone with a good memory and a happy childhood remembers so fondly. That state of being is what I'm pointing to.
