Consciousness as you know it, or as you conceive it, may or may not have an object but must have a substrate, something on which its natural confidence in its own continuity is based. In the first instance this is the body, and going further it might be the soul or the self, or God, something unknowable on which it rests, something of a different nature, say pure self-sufficient being. If consciousness were a computation it would be the 'computer' actually running that computation. The computation itself is a piece of abstract mathematics, existing only for consciousness without distinction from any other such computation, lacking the 'fire' which instantiates it. 'Consciousness only' teachings lack this element, it is only tacitly assumed. What could a consciousness e that was its own substrate? Is the notion coherent? All thought breaks off at this point.
