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.
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.
In the words of the ancients, one should make his decisions within the space of seven breaths. It is a matter of being determined and having the spirit to break right through to the other side.
Be detached from desire your whole life long.
You have power over your mind — not outside events. Realize this, and you will find strength.
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.
