Heaven and hell

Hi, I couldnt find it before. But what do you guys think about heaven and hell? Yami is called the lord of the land of darkness, but it is never called hell. The bestiary scrolls do mention hell many times, if okamiden is a canon, we have the demon market that seems to be another dimension, do you think that is hell? We also have talks of himikos soul ascending to the heavens, do you think that means the celestial plain? It doesnt seem to me that the fading celestials thought they were going there. Also the celestial plain is a physical location seen from nippon. Do you guys think the heavens os a different dimension afterlife separate from the celestial plain?
