To realise that the sole reality is pure non-objective awareness is not to call on a reserve behind experience but actually to do away with any such reserve, with the possibility of any such possibility. Your objective existence, which can only be your existence for others since you cannot be your own object, is just such a reserve, a sort of option on immortality. That there can be nothing but experience abolishes this, and it is a sort of irony to refer to this realisation as emptiness. Whatever it is empty of was never there in the first place, was only a kind of thought, or not even that.
