"At the still point of the turning world. Neither flesh nor fleshless;

Neither from nor towards; at the still point, there the dance is,But neither arrest nor movement. And do not call it fixity,Where past and future are gathered. Neither movement from nor towards,Neither ascent nor decline. Except for the point, the still point,There would be no dance, and there is only the dance."

---T S Eliot, Burnt Norton

Polarity and the still point....where opposites exist and do not exist.  Isn't this the place we need to find in all of our lives?  The partners must be present for the dance, but we rest in the stillness.  Applications are everywhere.  If only one of the partners fills our consciousness, the dance does not take place and neither does the stillness and the rest......
