“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. No one seems
to have noticed this fact. But grasping this firmly, one must
pile experience upon experience. And once one has come to this
understanding he will be a different person from that point on,
though he may not always bear it in mind.
When one understands this settling into single-mindedness
well, his affairs will thin out. Loyalty is also contained within
~ from Hagakure – The Book of the Samurai by Yamamoto Tsunetomo (William Scott Wilson’s translation)
and from the same source, different translation;
“All that matters is having single-minded purpose (ichinen), in the here and now. Life is an ongoing succession of ‘one will’ at a time, each and every moment. A man who realizes this truth need not hurry to do, or seek, anything else anymore. Just live in the present with single-minded purpose. People forget this important truth, and keep seeking other things to accomplish.”
~ Yamamoto Tsunetomo, Hagakure: The Book of the Samurai (Alexander Bennett translation)
