Sun Tzu (Chinese strategist and philosopher, 6th-5th Century BCE)
“Be rushing as a wind;
Be stately as a forest;
Be ravaging as a fire;
Be still as a mountain.
Be inscrutable as night;
Be swift as thunder or lightning.”
- From Sun Tzu’s The Art of War (Chapter 7), translated by John Minford (Penguin Classics, 2009).
