The Book of Five Rings
Musashi spent many years studying Buddhism and swordsmanship. He was an accomplished artist, sculptor, and calligrapher. Records also show that he had architectural skills. Also, he seems to have had a rather straightforward approach to combat, with no additional frills or aesthetic considerations. This was probably due to his real-life combat experience; although in his later life, Musashi followed the more artistic. He made various Zen brush paintings, calligraphy, and sculpted wood and metal. Even in "The Book of Five Rings" he emphasizes that samurai should understand other professions as well. It should be understood that Musashi's writings were very ambiguous, and translating them into English makes them even more so; that is why so many different translations of "The Book of Five Rings" can be found. To gain further insight into Musashi's principles and personality, one could read his other works, such as "Dokkōdō" and "Hyoho Shiji ni Kajo".
