A couple of concepts side-by-side. I think they have something to say about each other.
Gus diZerega, in Beyond the Burning Times [paraphrase]: in pagan thought, the immanence of God has, of necessity, to mean a diverse and multifarious world, each immanent expression offering a unique perspective on God as transcendent being, without which the whole would not know itself completely.
Beatrice A. Wright and Shane J. Lopez, in Chapter 3, Handbook of Positive Psychology: 'labeling groups leads to a muting of perceived within-group differences and a highlighting of perceived between-group differences' (p.27)
The second concept implies that from the perspective of a single self-aware observer, everything else would appear different, but allows that if the observer defines him or herself as part of a whole, differences disappear, and self awareness becomes awareness of the whole group, and awareness of any part of the group becomes awareness of the self.
