The ontological difference results from a quirk in functioning which splits it in manifestation into noetic and noematic poles. The mental self or persona is a subsequent effect, a back-projection of noesis in the context of this distinction. Non-dual functioning in its manifestation brings about these two poles with equal and opposite weight, and in so far as it is intuited it can be regarded as the veritable self, or subject. The projected mental self is variable, discontinuous and inconsistent and deficient in relation to its world which is thoroughly noematic. This deficiency is felt and is deeply pervasive, there is no place that this self can stand secure of it; it appears as judgement of the personal self, where the genitive is alternately subjective and objective. Judgement swings between high and low, guilty and innocent, good and bad, and can never be final. Effort and strain are always present, attempting to bring it right. When you look within for the subject, and foolishly that is where you look, as if inside and outside were a real distinction, you only find traces of the personal self which are always too small, mismatched to the conception. The self's failure to be subject is measured in sin, which is a reality only for this self. It invents the project of improving and purifying itself. States arise, often of tremendous positivity and almost success which point out to you the direction of the true self. None of this is in the least appropriate, or, as they say, 'fit for purpose', the directions are wrong from the outset, but the production of cultural values justifies it. And indeed things do go better with this unreal thing.
