The "true warrior" during the middle Samurai era belonged to the aristocratic class and was skilled in combat, strategy, the Chinese classics, calligraphy and other arts to produce a well-rounded individual. A combination of hard and soft. Miyamoto Musashi, a warrior of some note, also engaged in wood sculpture, painting and some poetry. To be immersed in an environment where violent death lurked in every corner, such training would help cope with the pressures of being a warrior, ready and willing to accept death at any time it was called for. Arts such as sumi-e ink painting and flower arranging require a spiritual calmness and emptiness that can aid in dealing with such a lifestyle. Yin + yang = balance and completeness.
