"The Way of the Samurai is found in death. When it comes to either/or, there is only the quick choice of death. It is not particularly difficult. Be determined and advance. To say that dying without reaching one's aim is to die a dog's death is the frivolous way of sophisticates. When pressed with the choice of life or death, it is not necessary to gain one's aim.
"We all want to live. And in large part we make our logic according to what we like. But not having attained our aim and continuing to live is cowardice. This is a thin and dangerous line. To die without gaming one's aim is a dog's death, and fanaticism. But there is no shame in this. This is the substance of the Way of the Samurai. If by setting one's heart right every morning and evening, one is able to live as though his body were already dead, and so he gains freedom in the Way. His whole life will be without blame, and he will succeed in his calling."
From the 2nd Chapter:
"Even if one's head were to be suddenly cut off, he should be able to do one more action with certainty. The last moments of Nitta Yoshisada are proof of this . Had his spirit been weak, he would have fallen the moment his head was severed. Recently, there is the example of Ono Doken. These actions occurred because of simple determination. With martial valor, if one becomes like a revengeful ghost and shows great determination, though his head is cut off, he should not die."
"At times of great trouble or disaster, one word will suffice. At times of happiness, too, one word will be enough. And when meeting or talking with others, one word will do. One should think well and then speak. This is clear and firm, and one should learn it with no doubts. It is a matter of putting forth one's whole effort and having the correct attitude previously. This is very difficult to explain but is something that everyone should work on in his heart. If a person has not learned this in his heart, it is not likely that he will understand it."
Again, from the 1st Chapter:
"There is something to be learned from a rainstorm. When meeting with a sudden shower, you try not to get wet and run quickly along the road. But in doing such things as passing under the eaves of houses, you still get wet. When you are resolved from the beginning, you will not be perplexed, though you still get the same soaking. This understanding extends to everything."
