The concept of “Kannin Dokuson” (1), the Mutō Dori of 2017 involves the control of the center of space.
Since Albert Einstein, we know that time and space are interconnected. They are like inyō. There is no duality, only a space-time unity.
Sayû, the well-known Bujinkan principle of “left-right”, also means “control”. Once again, it is similar to “inyō” (the Japanese “yinyang”). Therefore controlling the space is to control the unified interaction of yinyang within time. (2)
Last November, Sensei said the Kaname was to control the centre of the space delimited by the two opponents. (3)
A few months later, I understand it better. He was preparing us to get the simple complexity of “Kannin Dokuson”: “mutual respect, self-respect, respect of the attacker”.
The moment you control the space between, and around, the two opponents, you are capable to control Time itself. Therefore we can see Uchû Sayû (宇宙左右), the “control of space-time” (4) , as Uchû Sayû (裏中左右), “to control the invisible center of a situation”. (5)
