“To become the enemy, see yourself as the enemy of the enemy”
“common enemies make enemies become friends!”
“To know your Enemy, you must become your Enemy.”
“The greatest enemy is conquered only in death. Your greatest enemy is yourself.”
“In order to know your enemy, you must become your enemy.”
“Know the enemy and know yourself; in a hundred battles you will never be in peril. When you are ignorant of the enemy, but know yourself, your chances of winning or losing are equal. If ignorant both of your enemy and yourself, you are certain in every battle to be in peril.”
