Re his Technique, the Hitotsu-Tachi – One Stroke Then Death
“A sword can be divided into three spheres. The first is time of the heavens; the second is the advantage of the earth; the third is combination of the earth and the heaens. This is the secret of hitotsu-tachi.”

Re the Hitotsu-Tachi (this advice makes no sense to me except that one should mind the ma/distance and just avoid strokes like the “moon in the water” instead of blocking so that one can attack at that moment.
“…a swordsman must first position himself directly opposite his opponent’s sword. He can place his sword either aloft before him or at his side; the only essential point is that he must look unprotected, provoking the opponent to a conventional attack. If the opponent’s sword is more than one inch away from his body, the swordsman should not parry his attack. When the sword is only a half inch away, however, the swordsman should take one step forward and slay his opponent. The essential factor is the ability to distinguish the narrow margin which separates and inch from a half inch. Because man is my nature a coward, he will almost always try to dodge an attacking sword. He may be able to resist a space of an inch but half an inch indubitably causes a response. Since your opponent expects a defensive posture. A dodge at even one inch, your lightning fast attack takes him completely off guard. The attack at this final point entails that after deal the hitotsu-tachi the swordsman must touch his opponent’s body.” – Masaki Masahide (1727)

Here is a story about the preliminaries to a duel that is very interesting due to the psychological manipulation involved.

Bokuden was once challenged to a dul with steel swords by a swordsman who wielded two swords so skillfully that he had never lost a match. Before accepting the challenge Bokuden amassed every shred of informnation that was available about his opponent. He sent a letter objecting to his opponent’s style saying that wielding a swrod skillfully with the left hand as well as with the right was unfair. Since this thinking was totally illogical and unreasonable, the challenger become angry and sent back a letter saying, “If you think my using a sword with my left hand is unfair, renounce the match.” Before accepting the challenge, Bokuden sent another ten letters on the same subject to hisopponent. By the day of the duel, the challenger was firmly convinced that his left hand would strike the victorious blow. Assured that Bokuden would be paying strict attention to the second sword, the challenger stepped up to the famous swordsman. But in a flash, Bokuden slashed the opponent’s arm and the duel was over.

He has a book of 98 poems called Bokuden Hyakushu and if anybody knows where to get it in English or even in Japanese, I’d like to know.
