Comparison between Aura and Essence

"Hm? What do you mean? It is equivalent to two levels of essence? How is that possible? You're not even talking about the second stage, but the first, where it is not yet possible to use your aura in combat. How can it be equivalent to those two levels?"

"It really is strange, but from what I was told, when you are in the process of accumulating aura inside your body, it is already strengthening your body."

"What? That can't be right. Before I got to the second stage of my aura, I have fought with people who were at the first two levels of their essence, and I never felt like I was at the same level as them."

"Well, what I said isn't wrong, but there's a reason you felt that way."

"There's a reason? What is it?"

"Do you know when you entered the first stage of aura?"

"The first stage? Hm ... I can't tell, after all, you can't use aura when you're in the first stage. How would I know when I entered it?"
