Very enlightening. I had previously only heard 'Kazushi' in martial arts used in the specific context of defeating Gracie Jiu-Jitsu (Sakuraba anyone?). LOL. Okay, okay, that was weak. I know. I know.
I was on the metro earlier, deep in meditation, when a ruffian came over and started causing trouble. He started pushing me with his bag, steadily increasing the force until it became very annoying. When I turned to him, before I could ask him to stop, he immediately started hurling abuse like a scoundrel. I performed a basic chin na - carotid artery strike combination and sent him to sleep. The rest of my journey was very peaceful, and passersby hailed me as a hero - Warrior Man
