Some time ago, I was sent the following question:
I have been researching the kuji/juji method, and one thing I could never understand is, how can koryu (classical Japanese martial training) training enable someone to switch to a state of muga almost instantly? With Shugendo, to which I already have been initiated, it’s more simple to understand, but not so with martial arts In the book The Deity and the Sword, Otake Risuke Sensei only mentions the difference between zen meditation and kuji very briefly, and doesn’t go into any real explanation how to achieve that, other than to mentioning the sanmitsu method itself. I have read anything I could on the subject, and even went to the Diet Library in Tokyo, but this question is difficult. Even though I have received transmission from another koryu, which includes such teaching, it’s still very hard to understand it could be done just by waking up every morning, and doing it towards the sun.
