The Martial Way, there is a very nice article describing Kyokushin Karate which was developed by the famous Mas Oyama.
An excerpt is below. The full post may be read here.
Kyokushin (極真) is a style of stand-up, full contact karate, founded in 1964 by Korean-Japanese Masutatsu (Mas) Oyama.
Kyokushin is Japanese for “the ultimate truth”, developed from the
determination of the pursuit of ultimate truth of mind, technique, and
body. Kyokushin is rooted in a philosophy of self-improvement,
discipline and hard training. It is grounded in both the Okinawan
Shuri-te traditions (such as Shorin-ryu and Shotokan) and hard and soft
characteristics of Naha-te and Tomari-te styles, such as Goju-ryu, and
also includes realistic fighting.
The founder, Sosai Masu Oyama, often said that the difference between
sports and Budō, or The Martial Way, is the path of self-discipline.

founded by a man who was dedicated to the Budō Way. Read more about this
