Sun Tzu says: The Art of War is of vital importance to the state. It is a matter of life and death, a road either to safety or to ruin. The Chinese Art of War by its author Sun Tzu is one of the most influential books in history. Throughout the centuries it would accompany generals, statesmen, and philosophers alike. Those who follow his teachings, who safeguard themselves against defeat and make sure of victory before the battle is fought, will triumph. Those who know everything about themselves and their enemies will achieve supreme excellence.
