lot of words in the comments so i skimmed them but aura is not mass it's like steam and they hold the steam in as so i think density and that is what gives power while using ten and add ren for more it also is like energy because without it we wouldn't survive because without it we would be week. i think in hxh they have researched this because everyone their has a specialty and i'm sure someone was curious so that is how they learned more.
