Final Participation (thinking from the real self: from that which is divine in us - God Immanent) is inhibited or blocked by many habits, assumptions and convictions that are nearly-universal among modern adults.
To an atheist-materialist; real self thinking is childish, psychotic, demented or merely wishful fantasy.
To an orthodox- (i.e. Not Romantic) Christian; real self thinking is pagan, demonic; contradicts church tradition, church authority, The Bible and mainstream theology.
To almost everyone; it is contradicted by mainstream institutions, officialdom and the law, economics, science, medicine and the mass media.
That is to say: in this mortal life of today; the thinking of our real self is socially maladaptive (and very probably biologically maladaptive).
For all these reasons; thinking from the real self tends to be incomplete, unintegrated or brief in duration. Soon we will cease to attend to our real self in face of one or several of these other factors.
Consequently, the tendency is to ignore it altogether - especially when intuitive heart-thinking contradicts whatever other factors to which we give primary authority and to which we accord validity.
But we can choose consciously to attend to the thinking of our real self; and give it primacy over other sources of thinking. We can choose to allow it to dominate.
And, in a world of loving creation - such as Heaven - thinking from the real self (Final Participation) is wholly (indeed necessarily) adaptive; it both fits-into and contributes-to that world.
