The final episode left me with the sensation of understanding nothing and everything at the same time.

I guess that is the beauty of this anime. The fights are not real fights because there is something more important behind them: values, beliefs, convictions, and purpose.

It is so weird, yet at the same time so real, that a big fight or an imposing enemy can disappear when you simply understand something. When you become what you believe, because the conflict is internal.

And most of the time, the enemy is yourself, your fears, your emotions, and your ego.

The only thing I can say after finishing it is this: if you decide to watch this anime, I suggest watching it a second or even a third time. I know it was a whole experience, but there is way more to it than the toothbrush scene.
