Sosai Masutatsu Oyama summed up his entire Martial Arts philosophy in these eleven mottoes, also known as the Zayu no Mei Juichi Kajo, which are central in his teaching.
Miyamoto Musashi (1584-1645), also known as Shinmen Takezō, Miyamoto Bennosuke or, by his Buddhist name, Niten Dōraku, was a Japanese undefeated swordsman and ronin. Musashi, as he was often simply known, became renowned through stories of his excellent swordsmanship in numerous duels, even from a very young age. He was the author of The Book of Five Rings
(Go Rin No Sho), a book on strategy, tactics, and philosophy that is still studied today. Miyamoto Musashi is widely considered as a Kensei and one of the greatest warriors of all time.
Morihei Ueshiba believed that the real way of the warrior is based on the compassion, wisdom, fearlessness, and love of nature, and thus his teachings are not strictly for the warrior, they are for the human race.
