Your brain is a great separator. It separates stuff into categories. It separates good from bad. It separates likes from dislikes and desires from repulsions. We need it to survive. We need the thinking mechanism of the brain tool to keep us well and safe and fulfilled. It is not however a good tool for waking up, enlightenment, satori, salvation, being born again or any other way of describing the experience of heaven on earth or nirvana. You can't discover ultimate truth with a conditioned brain.
What you are is not just your story. You are the source of your story. You are the consciousness that is aware of your story. Jesus would say you are spirit and flesh, source and manifestation. You are already complete exactly as you are including everything you think you are not...
The divine only knows one thing because the divine is all there is. God is all there is and there is no other. The natural state of awareness is to be intently aware. The natural state of consciousness is to be fully consciousness. God only knows oneness because oneness is all that there is.
By design, the formless manifests as form to experience the formlessness of form. God becomes a character in a dream to know dreaming in a dream. Awareness becomes form to experience awareness as awareness. In our moments of Attention! Attention! Attention! we are experiencing our true nature...only one.
