Perhaps the Treaty of the most authentic martial strategy.

Gorin-no-sh (, The Treaty of Five Rings) is a major strategy Treaty in Japan, since it is neither more nor less than "will", inheritance, Miyamoto Musashi, widely considered around the world as the greatest samurai of all time.
When you know that, basic, ordinary samurai is an individual who devotes his entire life (and death ...) at swordsmanship, with a level of rigor and devotion much higher than in Most other civilizations, we say that the strongest of them could not be anyone, and reason: Musashi would indeed won, during his life, died at sixty duels.
But when such a man book, on the evening of his life, his advice, it would be very unwise not to listen.

Attention, however, the book is difficult to access. It will mainly concern insiders; others will probably be disappointed. The treaty mainly fencing itself, the mindset, positions, approaches, schemes, how to move, to hit, and all the ideas and martial values ​​dear to Musashi.
Ethics and the samurai spirit are more developed in other classics of this culture: the Hagakure, the indomitable spirit ... and more.
Most are curious find, unfortunately, that a reading somewhat understandable and heavy, at about hermetic and ultimately boring and disappointing.

In terms of publishing in itself, in this case, the editions Guy Trédaniel gratify us the most remarkable French version that I have seen to date, with a good quality translation and a book very beautifully illustrated.
If the book is very good quality and if the pages are in color, however, is not a large connected format but a medium format, paperback.
Note also that this edition, exhaustive, includes two other works Musashi less dense (the Hyoho Sanjû-gokajô (Thirty-five Instructions on Strategy) and the Dokkodo (The path of loneliness)) and is prefaced to situate its historical context.
However, it is expensive: the modest grants may prefer the very good version of Budo Editions, more sober, with a translation just as satisfactory and above almost twice the price.
