"Sit like an old frog by the river, softly quiet and immobile, hunkered down on the smooth surface.
Do not force immobility. Sit just to be sitting, to be still for a while, to catch your breath. And when you need to flash your tongue out to catch a fly, do so.
Action will come from that space of alert deep stillness that does not preclude action, but rather prepares you for effective action. "
Hugh Milne, The Heart of Listening
