Understanding true martial arts.
Many people in the Western world practice martial arts as a sport, without the spirit of Zen or the Bushido as their foundation.
Without a foundation in Zen, one can hardly understand the full extent of the philosophy of the practice of martial arts. Without Zen, the practice of martial arts is a meaningless practice, and it becomes simply a sport like hockey or baseball. Of course, there is nothing wrong with sports, but they are only games that function as a form of amusement. However, the tradition of Budo, or Japanese martial arts, is of a higher dimension and is certainly more than a game.
Budo is a way to find peace and self-mastery. It is a teaching that enables you to perfectly understand the nature of your own mind and self, and to grow spiritually as a human being.
