Consciousness is its own activity. It veils and colours itself with its own activity. It pretends that it is different and holds differences much like a screen showing a beautiful sunrise is actually its own activity. 

This is not a screen observed by another, but it is a self-aware screen with the ability to watch the movie that is playing on itself. 

Consciousness is a dimensionless field of pure knowing. In the act of colouring itself and assuming shapes and activities it may appear to be something other than itself, but in ultimate reality everything is, in itself,  consciousness.
