It was written as a guide for the samurai Yagyu Munenori, who was a great swordsman and rival to the legendary Miyamoto Musashi. Takuan was a giant in the history of Zen; he was also a gardener, calligrapher, poet, author, adviser to samurai and shoguns, and a pivotal figure in Zen painting. He was known for his brilliance and acerbic wit. In these succinct and pointed essays, Takuan is concerned primarily with understanding and refining the mind—both generally and when faced with conflict. The Unfettered Mind was a major influence on the classic manifestos on swordsmanship that came after it, including Miyamoto Musashi's Book of Five Rings and Yagyu Munenori's Life-Giving Sword .","forthcoming":false,"isbn13":"9781590309865","publication_date":"20120612","publisher":"Shambhala","slug":"the-unfettered-mind","subtitle":"Writings From a Zen Master to a Master Swordsman","title":"The Unfettered Mind"},"discovery":{"categories":{"all":[{"bisac_code":"PHI025000","confidence_band":"high","label":"Zen","score":1,"source":"onix_publisher_code"},{"bisac_code":"REL092000","confidence_band":"high","label":"Zen Buddhism","score":1,"source":"onix_publisher_code"},{"bisac_code":"SPO027000","confidence_band":"high","label":"Martial Arts","score":1,"source":"onix_publisher_code"}],"hint":[],"publisher":[{"bisac_code":"PHI025000","confidence_band":"high","label":"Zen","score":1,"source":"onix_publisher_code"},{"bisac_code":"REL092000","confidence_band":"high","label":"Zen Buddhism","score":1,"source":"onix_publisher_code"},{"bisac_code":"SPO027000","confidence_band":"high","label":"Martial Arts","score":1,"source":"onix_publisher_code"}]},"genres":[{"label":"Zen","score":1,"slug":"zen"},{"label":"Zen Buddhism","score":1,"slug":"zen-buddhism"},{"label":"Martial Arts","score":1,"slug":"martial-arts"}],"reader_fit":["Good for readers interested in buddhism","Good for fans of Philosophy","Good for readers who enjoy Zen and Zen Buddhism."],"related_lists":[],"series":null,"similar_books":[{"authors":["Charlotte Joko Beck","Brenda Beck Hess","Barbara Barnes","Shambhala Publications"],"book_id":"9781611808773","cover_image_url":"https://img.bookfrontier.com/9781611808773.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":17.3967,"title":"Ordinary Wonder","url":"https://bookfrontier.com/books/9781611808773"},{"authors":["Philip Kapleau Roshi","Philip Kapleau"],"book_id":"9780385260930","cover_image_url":"https://img.bookfrontier.com/9780385260930.jpg?v=20260402T191500Z-bisacv2site-fullset%3A2026-04-05T10%3A13%3A18Z","score":10.4542,"title":"The Three Pillars of Zen","url":"https://bookfrontier.com/books/9780385260930"},{"authors":["Alan Watts","Alan W.
