The classical budo, or "martial ways" are not combat systems like their forerunner, bujutsu, or "martial arts"; nor are they sports like modern judo, kendo, or karate. They are first and foremost spiritual disciplines, whose ultimate goal, achieved through the most rigorous mental and physical training, is self-realization in the tradition of Zen Buddhism. The author details the history, philosophy, and methods of a variety of these "martial ways," some using weapons, and some weaponless.
