Okay, here's an easy question: how are humans able to stand on two feet without falling over? There are several complicated ways to answer this, but the simplest and most basic truth is, we balance. This ability to be bipedal is an evolutionary miracle, but it's so automatic that we take it for granted. Until an injury or illness makes that impossible or difficult, we don't typically appreciate this balancing act. Partly it's because we do not understand what balance is. People who come for Alexander lessons anticipate that their balance will improve, and that's almost always a predictable result. Yet most students are surprised to learn that balance is dynamic, not static. One doesn't maintain balance by holding on, but by letting go. Or, to be more precise, by letting flow. Balance is a series of continual adjustments, tiny micro-motions that can only occur when there is openness and ease in the body. The minute we hold to a fixed posture or become rigid, we lose our balance. When tension and gripping is released, dynamic adjustments automatically flow throughout the system.
You may be thinking, "I'm pretty tense a lot of the time, but I don't fall over. I stay balanced." Well, you might stay upright, but that's not the same thing. Holding a fixed pattern in the body comes at a cost, in terms of muscle overwork and discomfort, reduced respiration, and the muting of feeling and reliable sensory feedback (to name just a few of the downsides).
Bodymind Experiment: Stand in a comfortable way, with your feet hip-width apart. (If you can do this without shoes, all the better.) Check in with your knees, make sure they are not hyperextended or locked. Relax your lower back, your belly, and your chest. Allow your arms to hang easily at your sides. Do a quick scan to see where there are pockets of tension (forehead, jaw, shoulders, thighs -- all popular spots for tightness). Invite these places to soften. Take a few full breaths, in through the nose, out through the mouth. Now, with your eyes closed, begin to notice the movements happening in the soles of your feet. There will be little shifts back and forth, or side to side, or in circles. Don't do anything about this, just notice it. You will observe that even when we are "standing still" there is movement. Open your eyes, and sense the same micro-movements happening.
This is your body doing its best to balance. Keep scanning the body and the mind for little pockets of tension, and as you stand there, see what happens when you keep releasing wherever you are holding. How does this affect the motion you noticed in your feet? You can also try tensing up a bunch, to see what that does to the balancing act. Grip, then let go. Let go some more. Breathe.
Are you in the dance of dynamic balance?
