I would say that the central pivot point of our Way is to ALWAYS have stillness within.
However, the meaning of "stillness" is perhaps a little special in a Zenny
sort of way ...
That's because it is a "Stillness" that expresses itself as both life's stillness and life's motion ... a Peace of One Piece
found in peace and even in sometime war and chaos.
It is a "Stillness" found both sitting quietly and unmoving on the Zafu or running toward the goal line on the football field or running like hell from life's hungry tigers!
It is a "Stillness within" that we may come to see is not limited by "within" or "without", but sweeps in and vibrantly dances all the world.
It is a "Stillness" that is perfectly still and always present when seen and sensed and when not seen at all at dark times ... much like the shining moon is always present in the sky even when hidden by clouds in the dark night.
So, this Practice is founded upon coming to know that Stillness on the cushion and off ... sitting, standing, walking, running or flying through the air
... sweeping in and sweeping out both inside and out
Something like that.
