[The Japanese practice of] SHIZUKA: "Peaceful stillness." In the varied Japanese Ways, a still and peaceful state of mind is valued. When the mind is calm and immovable — even in the midst of physical activity — then the body relaxes and each body part settles naturally into its proper position. Most traditional Japanese art forms simultaneously unearth, cultivate, and express this condition of dynamic serenity.
