''The school of Zen associated with Rinzai (d. 866) is known
for its dynamic style and its emphasis on the body: all activity
can be meditation; wisdom must manifest in every action
of the realized person.
The Rinzai school became the dominant school of Zen
in China, and was eventually transmitted to Japan''.
