There is neither duality nor nonduality in Consciousness, since both are nothing but concepts. This means that Consciousness cannot be objectified, but is transcendent to all objectification. Consciousness includes all existence, all absence of existence, and all that transcends both existence and non-existence. Even though it cannot be described, we attempt to represent it by the structure shown below. This structure is conceptual only, not real, because, in fact, there is no separation of any kind.
All separation is conceptual, thus, all objects are conceptual.
Since no object is real, no object exists. We use concepts in order to be able to communicate with each other about Consciousness. In actuality, there is only Consciousness and there is nothing but Consciousness. Indeed, the manifestation itself, including the illusion of physical causation, appears completely spontaneously. For the purposes of communication, we may sometimes say that all that appears to happen, including all thinking, feeling and doing, is done by Consciousness, Totality, or God.
