In my opinion, one of the worse things to happen to contemporary martial arts is MMA. By this standard, popular opinion has it that a given martial artist is boastful, crude, and violent. That may be true in some cases, but it does not apply to Budo, which is dependent on Bushido and the concept of Bunbu Ryodo. Bushido is a code of ethics and behavior, appropriate for the warrior class and analogous to chivalry in the West. Bunbu Ryodo is the way of the sword and the pen. It is an approach to life that blends martial and cultural arts. By this standard, the Bujustsuka is far from the archetypical professional wrestler presented by the mass media.
The best reference to Bushido is the book by Inazo Nitobe, Bushido: The Soul of Japan
A good reference to Bunbu Ryodo is the following article on Web Dojo
The best way to understand these concepts is to practice them.
