...go back to the Eiffel Tower image and, after having stood erect, 'but relaxed', and forwar over the insteps of the feet, we use .. the muscles of the insides of the thighs to pull our upper thighs and knees inward. Without tension, we have created, now, not only a vertical center, but a horizontal center (very much like the tower), and we are indeed grounded..
apart not together in order to hold balance. I don't need to keep pulling the legs together once they are standing together.
.. comment, please?
