Ramatumula

“If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is temperamental, seek to irritate him. Pretend to be weak, that he may grow arrogant. If he is taking his ease, give him no rest. If his forces are united, separate them. If sovereign and subject are in accord, put division between them. Attack him where he is unprepared, appear where you are not expected .”
― Sun Tzu, The Art of War

“Thus we may know that there are five essentials for victory:
1 He will win who knows when to fight and when not to fight.
2 He will win who knows how to handle both superior and inferior forces.
3 He will win whose army is animated by the same spirit throughout all its ranks.
4 He will win who, prepared himself, waits to take the enemy unprepared.
5 He will win who has military capacity and is not interfered with by the sovereign.”
― Sun Tzu, The Art of War

“Supreme excellence consists of breaking the enemy's resistance without fighting.”
― Sun Tzu, The Art of War

“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, The Art of War
