The Book of Five Rings: A Classic Text on the Japanese Way of the Sword by Miyamoto Musashi

informative mysterious reflective medium-paced

3.5

If you want to learn how to fight with a sword, boy is this not the book for you! As Miyamoto Musashi and Yagyu Munenori are at pains to repeatedly state, these texts are not a practical guide to swordplay; rather they are philosophical texts that underpin the essentials of sword mastery.
And it's really two books in one. Musashi's Book of Five Rings is a spartan text that simplifies the practice of swordsmanship to base principles; Munenori takes a poetic approach (which Musashi would probably dismiss) which expands more on the mentality of the sword. 
Both are very interesting if you have an interest in kendo or other martial arts, but if you're starting from base principles don't expect to become a master swordsman just from reading this book.
