A newly translatedsamurai textcalled " Twelve Rules of the Sword " let on the enigma of a sword - fighting school that control a proficiency that seemed to give supernatural power .
date back to the 17th century , the text contains noesis passed down from a samurai distinguish Itō Ittōsai ( born around 1560 ) , who fought and won 33 duels in Japan . Researchers are n’t sure when he die , but historical records suggest he may have exist to be over eld 90 . Ittōsai never write down his " Twelve Rules of the Sword , " and alternatively passed them on by word of mouth to his students at the One Cut blade - fighting school . The descendants of his scholarly person by and by recorded them in writing .

A Japanese samurai warrior, around 1880.
The text describes rule for flap an opponent as well as two magical prayers to heighten a samurai ’s spirit and psyche , fit in to Eric Shahan , who recentlytranslatedthe textbook . Shahan is a Japanese transcriber who specializes in translatingJapanese martial - arts texts . He also hold a San Dan ( third - degree black belt ) in Kobudō , a Japanese soldierly graphics .

The two magical prayers are wispy and hard to interpret . One of them states that a samurai should draw several Sanskrit character on their palms , including a persona that represents Oni , a type of demon . The samurai then joins their palm tree together , says a prayer , and rotates their hands one clock time while making a loud " Un ! " sound , before clap their hands once and itch them together , the prayer indicates .
Observing with your spirit
One of the dominion in the schoolbook is called " eyes of the heart " ; it say , in Shahan ’s version , that " you should not look at your opponent with your eyes , but consider them with your spirit … If you attend with your eye you may get cark , however by looking with your mind you stay focused . " Two wizard prayers that may have aid samurai of the One Cut school to view opponents with their " intent " and " head " were also translated into English in the text .
multitude living in seventeenth - century Japan who saw a samurai who had mastered the " centre of the warmness " rule may have been daze . " At the time , it may have seemed to an commentator that someone who had mastered this techniquehad supernatural powers , " Shahan say . However there is a scientific account for how they used their " intellect " and " spirit , " rather than eyes , to watch their opponent . [ Photos : nineteenth - Century Martial Arts for bull ]
harmonize to Shahan , " [ The ] account is you react faster to things moving in your peripheral vision as opposed to your center of stress . Looking now at an opponent ’s sword , consciously registering a trend and then attempt to respond will not end well for you in a blade affaire d’honneur . "

Shahan sum up , " Conversely , allowing your opposition to be in your field of vision without concentrate on any one part allows your peripheral vision to react to any effort or onrush , " and " you will react faster than you could by staring directly at the foeman . "
The magical prayers in the text were likely some eccentric of self - hypnosis or meditation ritual : " If your mind is in a jumble before battle , licking would be sealed . There could certainly be a connection to the eyes of the center in the sense that you want to set aside your body to react freely and unconsciously to the opponent ’s attack , " Shahan enjoin .
Heart of the fox
Another pattern , address " marrow of the slyboots , " warns samurai against being too cautious . The principle notice that fox are cautious and suspicious by nature , something that can get them pop . " Instead of fleeing in one direction , they break off here and there checking what is behind them . During one of these delays , the hunting watch circle around and drink down the slyboots . The moral here is that an excess of caution lead to the fox ’s downfall , " the prescript states .
If a samurai mean about what they should do and hesitates , " the adversary will choose that bit to chance upon " fit in to that formula . " Therefore , it is all important that you remove all doubt from your technique . You must vigorously check yourself so that you are empty , the void . "
The other prescript let in " pine tree in the current of air , " whichteaches samurainot to get trap by the opposite ' rhythm , but to use no rhythm at all . Another , called " cutting down , " involves attain split - second timing and " forestall extraneous thoughts . "

Shahan say that samurai who learned the One Cut schooltime of brand - fighting techniques " trained all their lives in the sword arts so the techniques were ingrained into their bodies ; they want the genial fortitude to earmark their body to respond without their judgement secondly guessing the situation .
