User blog comment:Silver-Haired Seireitou/Sei-san's Classroom: Beyond the Spiritual Skies/@comment-3045936-20120625021316

I have no idea, but this is part of a remade quote from one William Shakespeare that in English dubbed Code Geass Episode 15 in season 2 or R2 said by Charles zi Britannia. " There are worlds without end." Now, if you were take that concept to the Bleach universe it could be that the sky of the Soul Society could be the gate to the Soul Palace. And maybe after that its like the Garganta which Kisuke Urahara says as nothing but a Chaos of reishi. My own point is that maybe the spiritual realms are worlds that possible together are a universe that truly has no end or maybe each separate world is without end as its well.... not a place in the physical plain and is a spiritual/ethereal realm.
