Even when your spirit is calm do not let your body relax, and when your body is relaxed do not let your spirit slacken. Do not let your spirit be influenced by your body, or your body be influenced by your spirit.
Generally speaking, the Way of the warrior is resolute acceptance of death.
Accept everything just the way it is.
If a warrior is not unattached to life and death, he will be of no use whatsoever. The saying that "All abilities come from one mind" sounds as though it has to do with sentient matters, but it is in fact a matter of being unattached to life and death. With such non-attachment one can accomplish any feat.
Resolve your mental energy into abstraction, your physical energy into inaction. Allow yourself to fall in with the natural order of phenomena, without admitting the element of self,—and the empire will be governed.
Accept everything just the way it is.
