 Generally Zen describes the freedom of bodily movement as “stillness in motion” (dōchū no sei) and is contrasted with “motion in stillness.” It is noteworthy that “stillness in motion” cannot accurately be analyzed by appealing to the active-passive scheme, which presupposes a dichotomy as a proper method for understanding. However contradictory it may seem, this is a description of how Zen understands its freedom as expressed through an integrated mind and body. In order for this sense of freedom to be embodied, however, Zen emphasizes that a performer of any kind repeatedly undergoes mind-body training. Takuan calls this the “body’s learning,”—that is the core meaning of self-cultivation—because in the “body’s learning,” both the mind and the body are brought to action in one integrated whole. (The “body’s learning,” neurophysiologically speaking, is closely related to an activity of the cerebellum in conjunction with the hippocampus, although it is not only that.) When a skill or performing technique is learned through this method, one’s own body moves freely as it is habituated to move without waiting for a command from the mind. This describes a freedom of action in a Zen person for whom the mind is completely assimilated into the object-body, while the body is equally rendered into the subject-body. They are one. At such a time, Takuan says, a spiritual life-energy of psychophysiological nature, called “ki,” permeates “one’s body”—an energy that cannot be delineated by either the mind or the body (Yuasa, 1993). In this connection, Zen also speaks of Zen’s free action as a purposeless purpose, as an actionless action, for neither the purpose nor the action arises from the everyday consciousness which sets up a purpose or a goal for action. Zen calls it “samādhi-at-play,” where there is no individual qua the trans-individual, but what there is is just “play,” for the Zen person is absorbed in the activity when engaging a thing of the everyday lifeworld. In short, Zen freedom designates a term of achievement. What Zen says about freedom of action has an implication for every action people perform in daily life, from the simple act of opening a door to the magnificent play of a great athlete or performer of any kind. In them, Zen contends however, the spirituality of a performer must be expressed. Zen extends an invitation to all of us to act in this way, so that our quality of life will be enhanced with a sense of satisfaction and fulfillment, free from stress and anxiety.
