34th Grandmaster of the Togakure Ryu Ninpo, Soke - Head Master - of Bujinkan's 9 Martial Traditions
One never knows when a fight might start. That is why in Budo one keeps prepared, so that should a fight arise, one can settle it as quickly as possible. In a dangerous situation, you act swiftly, without any hesitation. That is the secret of winning. If you have to fight, remember that you have been entrusted with a mission and are serving a greater purpose, you must KNOW that you can win, and use this energy in your encounter.
In Shinto there is a word "Nakaima", which literally means "in the middle of now." It teaches us that the correct moment embodies the whole of time, and consequently, that how you live the current moment is of supreme importance. In the martial arts too, including Ninjutsu, each individual moment is important. It is important to live through each moment to the full, without wasting time on the pointless.
