User blog comment:VedranTheII/Pretentious Diaries 2: What tricks would you teach your Aura?/@comment-24994749-20150718160146

What I wonder is, can you track don someone by their aura? (You know, like in Bleach you can track down someone by their reiatsu.) If so, can you suppress your aura to avoid being detected? Could someone with a larger amount of aura project it to crush down someone with their presence?

(Basically, what I always wonder when concepts like these are introduced in a show.)
