So the principles of warfare are: Do not depend on the enemy not coming, but depend on our readiness against him. Do not depend on the enemy not attacking, but depend on our position that cannot be attacked.
To demand of strength that it should not express itself as strength, that it should not be a desire to overcome, a desire to throw down, a desire to become master, a thirst for enemies and resistances and triumphs, is just as absurd as to demand of weakness that it should express itself as strength.
To his enemies the householder must be a hero. Them he must resist. That is the duty of the householder. He must not sit down in a corner and weep, and talk nonsense about non-resistance. If he does not show himself a hero to his enemies he has not done his duty.
You may have enemies whom you hate, but not enemies whom you despise. You must be proud of your enemy: then the success of your enemy shall be your success too.
