One of the least understood forms of art in the world, budo requires faith to learn and courage to understand, as well as an array of physical skills and techniques. Among the fundamental teachings of budo is ninjutsu, the art of perseverance that forms the basis of the Japanese martial arts. The lessons in this book come directly from experiencing the living vitality of the world's foremost master of the ninja arts, Masaaki Hatsumi, who contributes the foreword. Through the use of stories, anecdotes, poetry, art, and thought-provoking quotations, Sleiman Azizi and Daniel Fletcher move beyond the stereotypical image of the ninja to offer a multifaceted reflection of the discipline, aesthetics, and philosophy that lies hidden within the martial way.
