Buddhism & the Samurai
The helmets, suits of armor, and weapons in Samurai: Armor from the Ann and Gabriel Barbier-Mueller Collection (on view through June 5) are exemplars of fine craftsmanship and functional protective gear. But there is another factor to these great works of art that helped shape, quite literally, the forms you see in this exhibition at the Denver Art Museum: Buddhism. Various forms of Buddhism played a major role in the life of the samurai, and we find this influence throughout several pieces on display.

Buddhism arrived in Japan during the sixth century and quickly became a powerful force for the ruling class. Though the indigenous practice of Shinto never disappeared (and, in fact many Shinto traditions merged with Buddhist ones), Buddhism and its various deity figures, rituals, and scriptures became quite influential. Pure Land Buddhism and the esoteric sects of Shingon and Tendai all contributed to the religious beliefs of the samurai.

Zen Buddhism & “the Way of the Warrior”

However, it was Zen Buddhism that best suited the warriors and complemented bushidō, the strict code of the samurai’s practice, or, “the way of the warrior.” Zen Buddhism eschewed the elaborate rituals and scriptures of Pure Land and the esoteric sects for the idea that all things are fleeting and enlightenment may be attained through spiritual and physical discipline. There was no concern for death, and this suited the samurai’s practice. The samurai must be ready to die at any moment—though the armor hopefully delayed that moment.

Seppuku (切腹, 'cutting [the] belly'), sometimes referred to as hara-kiri (腹切り, lit. 'abdomen/belly cutting', a native Japanese kun reading), is a form of Japanese ritual suicide by disembowelment. It was originally reserved for samurai in their code of honour but was also practised by other Japanese people during the Shōwa period (particularly officers near the end of World War II) to restore honour for themselves or for their families.
