My personal opinion is that Aura is like the magic in most epic fantasy seriess. It comes from the user. Therefore, it is affected by the user's personality and thoughts. If you really hate someone, your Aura might have more of an impact when punching them. To a certain extent, the stronger your convictions, the stronger your Aura. Of course, the amount of Aura a person has varies, so that would be hard to test.

As to the Dust part of this thread. We have clearly seen evidence that Dust comes in many forms, some of which are highly volatile. Ruby's sneeze likely set off some of the super-uber-insanely volatile stuff. Or it was already approaching its limit from something else, and the sneeze was just the final straw. Why wouldn't it be able to be set off by Aura?

And Aura was likely used in the Grimm war, even before Dust was discovered. I suspect that the use of Aura was the only way humans were able to stay alive until Dust was discovered. With the extra power of Dust, the balance of human:Grimm was finally tilted. Without Aura, the humans would have probably fallen to the Grimm long before Dust showed up.

For those who actually took the time to read this, sorry about it's length.
