From inside fortifications, the gun has no equal among weapons. It is the supreme weapon on the field before the ranks clash, but once swords are crossed the gun becomes useless.

Do not regret what you have done

Generally speaking, the Way of the warrior is resolute acceptance of death.

To become the enemy, see yourself as the enemy of the enemy

Think lightly of yourself and deeply of the world

True warriors are fierce because their training is fierce.

When in a fight to the death, one wants to employ all one's weapons to the utmost. I must say that to die with one's sword still sheathed is most regrettable.
