Passage 6-9

故形人而我無形, 則我專而敵分. 我專爲一, 敵分爲十, 是以十攻其一也.

Make the enemy take shape while I remain formless—then I am concentrated while the enemy is divided. Concentrated as one against their scattered ten, I strike with ten-to-one advantage.

"I am formless... I am concentrated, the enemy is divided" (形人而我無形). The strategic doctrine of formlessness — be unknowable while making the enemy knowable.
