Consciousness, as ground of all experience, is erroneously understood via a sensory analogy, as a something knowing a something in a perspective, in which it immediately unfolds as a relation of three distinguished parts: seer, seen and seeing. Against this is the realisation that the senses could not function as they do if the underlying consciousness were itself a kind of sense. You must either refrain from thinking of consciousness at all, perhaps denying its existence, or else turn towards an unthinkable pure inwardness without space or time, an intimate positive negative and negative positive,, darkness of light and light of darkness.
