I have learned a great deal from Asian philosophy and culture. I have not practiced martial arts, but I have studied their basic philosophy. Unfortunately, the Western interpretation and mutation of martial arts often blurs the lines between self defense to immobilize or fend off an aggressor and intentional or lethal harm to an aggressor.
There is power in living nonviolently, in my opinion. To firmly root oneself in nonviolent thought and nonviolent action takes practice. More practice for some than for others. Playing violent video games is not consistent with nonviolent practice. Supporting blood sports is not nonviolent practice. Joining the military is not nonviolent practice. Engaging in threatening speech or action is not nonviolent practice.
The key to nonviolent practice is the bridling of instinctive anger and conditioned anger. First, one must acknowledge the presence of anger in the moment. Then one must develop ways to deal with the anger immediately and consciously in the moment. Suppressing or repressing anger is not nonviolent practice. Acknowledging and channeling anger consciously and consistently is nonviolent practice. Exposing one's anger for what it is, accepting it and understanding its stimulus are essential conscious actions.
Many of us go through life experiencing habitual anger with roots in bad relationships in our pasts. This anger, if unexposed and left unattended to, will be an obstacle to many relationships. It will also inhibit personal growth.
Practice encompasses making conscious all the senses and all the emotions in our bodies. Then, moment by moment, mindful experience and channeling of our emotions builds a practice for personal growth. This is the central healing relationship we must build within ourselves before we can truthfully benefit the world around us in our practice as mindful, compassionate human beings in society.
