[527] The Blessed One said this:
"One should not run back to the past,
nor place longing upon the future;
what is past has been abandoned,
and the future has not yet been reached.
But whoever sees with insight the present phenomenon (dhamma)
just there, wherever it arises—
unfaltering, unshakable—
having known that, let him cultivate it.
Today itself the effort must be done;
who knows whether death will come tomorrow?
For there is no bargaining for us
with Death (Maccu) and his great army.
One who dwells thus, ardent (ātāpī),
untiring by day and by night—
it is he indeed whom the peaceful sage (muni) declares
'one whose single night is auspicious (bhaddekaratta).'"
