"From the beginning of the year to the end, day and night, morning and evening, in action and repose, in speech and in silence, the warrior must keep death constantly before him and have ever in mind that the one death [which he has to give] should not be suffered in vain. In other words [he must have perfect control over his own death] just as if he were holding an intemperate steed in rein. Only he who truly keeps death in mind this way can understand what is meant by [Yamaga Soko's maxim of] "preparedness.""
