"剮虛" It was a basic technique, one one first learns when you first hold a sword. It was simply the act of cutting a target into pieces. Yes, that was it, a technique that relied purely in your insticts. To call it a technique was absurd, but nonetheless, all the seven fundamental offensive stances ultimately harbor this so-called "technique". Indeed, it was intent. After you finally fold your Sword Art into 2 layers, the definition of "剮虛" changes completely. But is it truly just the intent left behind by [Sword Art]? It was not. Just as the "Sword Aura" those so-called Sword Sorcerers wield is not merely Sword Aura, 剮虛 is not merely intent: It was a principle. It is the principle left behind by your [Sword Art], its very essence. Indeed. Therefore, to fully manifest a Cut ( 剮虛), one must unfold your entire [Sword Art]. If in the 2nd Layer, you share your [Heart], then in the 3rd Layer, you share your [Essence] in the medium of the sword. Yes, indeed. Perhaps that is why at the apex of the 3rd Layer, your very [Essence] becomes your sword, an [Essence Sword]. Therefore, one can say the [Beginning Sword Realms] is meant to teach you basic speech, while [The 8 Divine Pathways] is meant to teach you how to express your emotions. In that case, the 3rd Fold is meant to teach you how to express your beliefs and opinions. It is a stage where you manipulate the world itself, imposing your Laws/Opinion (理). Perhaps.... [Sword Art] is a form of [Dialogue]
