Putting Your Awareness down in both "Bubbling Wells"

In the style of Tai Chi I practice it is important to train to place your awareness down in the bubbling wells of both feet. Even being accurate in "placing your mind" down in both bubbling wells is a difficult thing to maintain (in my experience). Anatomically it is quite a small point so constant care and sometimes visual checking is needed to see if you are indeed "focusing & feeling" that point at the soles of your feet. You might be accurate for one foot but because of slight anatomical differences (e.g. - an old sprain, an old injury, one leg being slightly different than the other, etc) which can result in one sole not sitting as flush with the ground as the other sole; hence being accurately aware of both simultaneously can be difficult.  When one leg/foot is different from the other, there may be a tendency to favour (grounding and rooting) and lean (distribute the weight and the Yang force) through one leg more than the other. For years I didn't realize that in my standing post exercises I favoured one leg over the other, and that my weight and force was not distributed evenly. This can lead to the hips not being level, which leads to other structural instabilities etc ... you get the point. In addition, when (and I do say "when") you can find some Tai Chi books that actually explain the "Bubbling Well" - they can be vague in their diagrams or differ in their anatomical positions (i.e - the middle, two-thirds etc). Once successful in being aware of both bubbling wells in the horse stance/standing post position (where the weight's distributed evenly), it can feel like a different ballgame when changing to the Tai Chi archer/bow and arrow stance. And in this stance it is arguably more important to sink the forces through the bubbling wells of both feet down into the ground.  So all in all, when you really work on practicing your bubbling well awareness, it might sound simple but it shou
