Zekko Arashi Ryu “The Benevolent Heart”
Designed by zekkoarashiryu
Zekko Arashi Ryu “The Benevolent Heart” JI-HI NO KOKORO is an ancient Japanese term which the Ninpo warrior reveres as the highest essence of the true warrior spirit, the ultimate weapon: “The Sword that is No-Sword.” * * * * * * * * * "For a samurai, a single word is important no matter where he may be. By just one single word martial valor can be made apparent. In peaceful times, too, one knows that by a single word his strength or cowardice can be seen. This single word is the flower of one's heart. It is not something said simply with one's mouth." --- from the Hagakure, The Book of the Samurai, --- by Yamamoto Tsunetomo, Japan, 1716
