Trace consciousness back to itself, unmixed with bodily sense-reports, emotional moods, or mental thoughts. This can be done successfully only by withdrawing it inwards as you analyse. The process becomes a meditation. In the final term you are aware of nothing else, that is, of nothing but being aware. But at this point you cannot know it as a second thing, an object, but only by being it.
