"If you know the enemy and know yourself, you need not fear the result of a hundred battles. If you know yourself but

not the enemy

, for every victory

gained you will

also suffer a defeat.

If you know neither

the enemy nor yourself,

you will succumb

in every battle." -Sun Tzu

"Be extremely

subtle

, even to the point of

formlessness

. Be extremely mysterious,

even to

the point of soundlessness.

Thereby you can

be the director of the

opponent's fate

." -Sun Tzu
