There is surely nothing other than the single purpose of the present moment. A man's whole life is a succession of moment after moment. If one fully understands the present moment, there will be nothing else to do, and nothing else to pursue. Live being true to the single purpose of the moment. Everyone lets the present moment slip by, then looks for it as though he thought it were somewhere else.
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.
Meditation on inevitable death should be performed daily. Every day when one's body and mind are at peace, one should meditate upon being ripped apart by arrows, rifles, spears and swords, being carried away by surging waves, being thrown into the midst of a great fire, being struck by lightning, being shaken to death by a great earthquake, falling from thousand-foot cliffs, dying of disease or committing seppuku at the death of one's master. And every day without fail one should consider himself as dead.
The scenes of life are like the pictures in a magic lantern: we see them, one after another, with vivid distinctness; but as soon as one vanishes, it is utterly forgotten; and then the next appears, completely different from what went before — though at bottom it is always the same story.
To every thing there is a season, and a time to every purpose under the heaven: A time to be born, and a time to die; a time to plant, and a time to pluck up that which is planted; A time to kill, and a time to heal; a time to break down, and a time to build up; A time to weep, and a time to laugh; a time to mourn, and a time to dance.
Nothing is permanent in all the world. All things are fluid; every image forms, wandering through change. Time itself flows on in constant motion, just like a river, for neither the river nor the swift hour can stop its course; but as wave impels wave, and as each wave comes, the one before is both impelled by the next and impels the one ahead, so time both flees and follows and is always new.
