The only religion that ought to be taught is the religion of fearlessness. Either in this world or in the world of religion, it is true that fear is the sure cause of degradation and sin. It is fear that brings misery, fear that brings death, fear that breeds evil. And what causes fear? Ignorance of our own nature.
I do not now so much as wish to have the Strength of Youth again that I wish'd in Youth for the Strength of an Ox or Elephant. For it is our Business only to make the best Use we can of the Powers granted us by Nature.
If your enemy is secure at all points, be prepared for him. If he is in superior strength, evade him. If your opponent is tempermental, 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.
All the strength and succour you want is within yourselves. Therefore make your own future. "Let the dead past bury its dead." The infinite future is before you.
