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 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.
Our actual enemy is not any force exterior to ourselves, but our own crying weaknesses, our cowardice, our selfishness, our hypocrisy, our purblind sentimentalism.
The best time to stop a fight is before it starts.
The best vitamin for developing friends is B1.
The best way to destroy an enemy in to make him a friend.
