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.
