“If you know yourself but not the enemy, for every victory gained you will also suffer a defeat.”

“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.”

“Hence the saying: 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.”

“If you seek Truth, you will not seek to gain a victory by every possible means; and when you have found Truth, you need not fear being defeated.”

“If you know the enemy and know yourself, your victory will not stand in doubt; if you know Heaven and know Earth, you may make your victory complete.”

“Hate is your enemy; you must defeat it! Anger is your enemy; you must defeat it! Violence is your enemy; you must defeat it! Death is your enemy; you must defeat it! Know well your real enemies!”
