“To become the enemy, see yourself as the enemy of the enemy”
“If you do not control the enemy, the enemy will control you”
“The primary thing when you take a sword in your hands is your intention to cut the enemy, whatever the means. Whenever you parry, hit, spring, strike or touch the enemy's cutting sword, you must cut the enemy in the same movement. It is essential to attain this. If you think only of hitting, springing, striking or touching the enemy, you will not be able actually to cut him.”
“When you decide to attack, keep calm and dash in quickly, forestalling the enemy...attack with a feeling of constantly crushing the enemy, from first to last.”
“Know your enemy, know his sword.”
“The important thing in strategy is to suppress the enemy's useful actions but allow his useless actions”
“Do not sleep under a roof. Carry no money or food. Go alone to places frightening to the common brand of men. Become a criminal of purpose. Be put in jail, and extricate yourself by your own wisdom.”
