In his writings compiled under the title “The Unfettered Mind,” Takuan Soho talks about the mind that does not fixate on anything—not it’s own thoughts or intentions, not on any action of the body, nor on anything happening in one’s external environment. He says about this state “When this No-Mind has been well developed, the mind does not stop with one thing nor does it lack any one thing. It is like water overflowing and exists within itself. It appears appropriately when facing a time of need. The mind that becomes fixed and stops in one place does not function freely.”
In taiji, we practice standing post in the wuji posture. The goal of this exercise is just like that of Takuan’s “No-Mind,” but applied to the body as well.We seek to develop a state of body in which we do not fixate on any particular shape, motion, or intention—not our own nor that of anyone else. Wuji is often thought of as the void, the center, or neutral. These terms however have a certain static quality. They make wuji sound like a thing. As a thing, it can be fixated on. What makes wuji the essence of fluid response and effortless interaction is that it isn’t static. Wuji is a constant state of unmanifested potential.
My favorite analogy for wuji, as it applies to both mind and body, is the smooth surface of calm water. In its resting state it is shapeless, motionless. However, the moment a pebble drops into it, it makes ripples. When you put it into a container it takes the shape of that container. When no more pebbles drop, when you pour it out of its container, it returns to its calm, smooth state. This notion of going from stillness to motion, shapeless to shape, then returning to stillness and shapelessness is in the very nature of water. It is always in a state of potential. The potential for motion remains a part of its stillness. The potential for stillness remains a part of its motion.
You could say, that water is always discovering what motion and what shape it will take, in accordance with external forces and shapes. It has no particular intention, no desire. It isn’t trying. Water doesn’t do anything. This is the idea of Wuwei (non-doing). In the same way, our bodies should always be discovering what movements, shapes, and forces they will make, in accordance with that of the other person or persons we’re interacting with.
So, to say no-mind is to say no particular mind, or the mind that has yet to manifest any thought or intention. To say no-body is to say the body that has yet to manifest any action. Yet this mind and this body are suffused with potential for thought, and potential for action. Even when in the midst of thought and action, the mind of no-mind and the body of no-body still have the potential for instantly and spontaneously changing thought and action according to the external circumstances. That is because the actions of such a mind and body are manifested by, for, and with the external circumstance, and never imposed upon them.
This mind of no-mind and body of no-body are the goal of all taiji practice.
