The unknowable subject

The 'I am' and 'the felt sense of being' are still objects in awareness and therefore not who I am. I am the empty, luminous, aware spaciousness in which they appear. This empty, aware spaciousness can never be an object, only the unknowable subject. Why? When empty, luminous awareness becomes aware of itself, all distinctions between the seer and the seen collapse, leaving only seeing/awareness.
