In perusing Youtube for worthy attention, I can always be engaged and transfixed by old recordings of Alan Watts, and his immensely accurate mental drawings of the reality of actual experience. I'm not sure they knew of each other, and Alan Watts certainly makes no mention of Alexander's technique that I know of. However, I think it is inevitable to cite and compare his innovative work to Alexander's because of the parallel descriptions they bring forth independently. This clip of a talk is a good example:
He discusses the possibility of "Ego" as being "a chronic habitual sense of muscular strain", for reasons that he lays out in the clip. Alexander said something like, "we translate everything physical, mental or spiritual, into muscle tension." In a way, we have very little choice given the language we are given for understanding: "A grasp on things", "Apprehending", "getting a handle on", even "making sense of" is an idea from nothing but impression. Our central coordinating system, for better or worse, works just fine without us. And our concept of who we are at any given moment, if bought into, can have unforeseen affects if we grasp too tightly onto anything that is not in front of you. So let go. For a second or a minute, or few days. Let it just operate. Do what you need, which is in front of you. And take as much time as it takes.
