So why would a peaceful Buddhist want to practice martial arts? Well, there are a many factors. Martial arts is a great way of teaching oneself self discipline, and training the mind. When training the body, we also train the mind. Constantly focusing and being mindful of the body has many benefits not only in a martial aspect, but also of health. The ultimate goal is achieving 'No-Mind." Zen or mushin.

As far as action movies loaded with lots of violence, even involving martial arts, I'm not a fan. Though I do collect rare Martial Arts movies from China and Japan, I tend to stick with the ones that have a good moral message or a message about training.
It is my hope that folks don't associate martial artists as violent people, (the ones who truly practic The Way), but rather as peaceful people who know when to act upon a situation when called for. Whether it be something as small as making a decision, or as important as saving your life.
