As Quoted in The Gerorgian Times in 2008 http://www.geotimes.ge/index.php?m=home&newsid=12354.eng
“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.”
Hagakure (c. 1716)
Source: Hagakure: The Book of the Samurai
Context: 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.
