@Qaf,
You appear to be taking a Kantian line on 'insight' ( his
transcendental unity of apperception). It is certainly the case that 'the observation of observation'..a phrase which might describe our
understanding of 'nonduality'(etc).... is certainly suggested from a level other than the 'pure reason' which was the subject of Kant's critique. But that level, although 'transcendent' need not imply
closure in the form of an absolutist entity which some might call 'God'. Such closure may be nothing more than psychological wish fulfilment...a safe cocoon to insulate the believer from 'the void'.
NB You might be interested in following up references to 'second order cybernetics' (the
Systems Theory term for 'observation of observation') in which Bernard Scott ( a believer) goes for closure, whereas Von Foerster argues for the possibility of unbounded levels of transcendent rationality.
