Native reality is reality without any cognitive filters or constructs, it is the ground truth. We live and perceive the world through many degrees of mental separation, layers that make the world more comprehensible. I believe that most of us take it too far, and end up living in a mentally produced hologram of reality, heavily colored by biases and artificial perceptions (objects that exist in belief only).
It is better that you always stay as native to reality as possible, even as you learn, grow, and evolve, building upon yourself, it should feel like ultimately "lateral" movements, like sidegrades.
Less like operating in higher, greater modes, and more like switching to a better lane/turning to the correct road direction.
Think of "native objects", like objects that exist in native reality, rather than in your mind, which then need to be translated to native reality.
Even mental constructs (like any mathematical thing) should be thought of as an object in native reality, rather than an arbitrary, dreamed up object that exists separately to the world.
