Saying humans are embodied spirits is just another way of saying humans are indefinabilities that become conscious of their own existence. We can comprehend what a human is because we know everything that we do and everything that happens to us. But we can’t define or explicate what a human being is. 

The word "level” implies a hierarchy or cardinal system: level 1, level 2, level 3. The human mind has four such levels: observation, inquiry, reflective judgment, deciding what to do with our bodies. The human mind either observes things or asks questions. The human mind does not have a function that lies between observing and asking questions. 

The metaphysical definition of self-awareness is that it is the ability to turn in on yourself and catch yourself in the act of your own existence. Defining self-awareness as being able to recognize your self in the mirror is the scientific definition of self-awareness.
