Like many people recently I havn't been able to get much martial stuff in, except for footwork exercise's and leg stretches so a lot of my stuff has been directed to a lot of reading. Last night I was glancing through 'Yagyu Munenori's' - Heihō kadensho, promoted by a recent comment by Jaydub on Mushashi's Book of the 5 Rings, so I decided to compare them seeing as they are seen still in Japan as fundamental to Samurai martial arts. This prompted me to reread The Demon's Sermon on the Martial Arts and other tales by Issai Chozanshi, which is probably my favourite. The Heihō kadensho is certainly very interesting for me seeing as it's the principles of swordsmanship as applied to Statecraft (He was very close to the Shogunate) as I studied political science at Uni. But what was interesting is the admonition like the other two which is an admonition that true martial arts is the ability to reach 'no mind' and let the techniques manifest themselves spontaneously rather than them be attached to the mind. In short Mushin: Mushin (mental state) - Wikipedia When I left Uni I was deeply influenced by Mihály Csíkszentmihályi book Flow, which detailed the mental state of 'Being in the zone' : Flow (psychology) - Wikipedia , which as a fencer on the circuit was seminal reading - how to try and reach the sweet spot where you are totally engaged on the strip and techniques and tactics through a total autotelic experience where you reach a state of Effortless hyperfocus . I think I even reached that bliss once or twice, but was always elusive, much the same experience I had with Taijiquan. (I guess I ruminate too much). Recently I finally got round to belatedly reading Timothy Galway's Inner game of Tennis, which is treads kind of the same path, but from the point of view of a Coach that is trying to get out of the athlete's way. They are often conflated as peak experiences.... But are they the same thing? Are there mappers who have achieved Mushin and do they believe it to be the same as Flow?
