[563] Then those bhikkhus, having delighted in and rejoiced at the words of the venerable Mahākaccāna, rose from their seats and approached the Blessed One; having approached and paid homage to the Blessed One, they sat down to one side. Seated to one side, those bhikkhus said this to the Blessed One: "Venerable sir, when the Blessed One had recited a summary (uddesa) in brief to us, without analyzing the meaning in detail, he rose from his seat and entered the dwelling:
'One should not run back to the past …
It is that one, truly, whom the peaceful sage calls "one who has one auspicious night (bhaddekaratta)."'
Then, venerable sir, not long after the Blessed One had departed, this occurred to us: 'Friends, the Blessed One recited this summary in brief to us, and without analyzing the meaning in detail he rose from his seat and entered the dwelling:
One should not run back to the past,
nor place hope in the future;
what is past has been abandoned,
and the future has not yet arrived.
Whoever sees with insight, here and now,
each presently arisen dhamma—
unshaken, unmoved—
having known that, let him cultivate it.
Today the effort must be made, ardently;
who knows whether death will come tomorrow?
For there is no bargaining for us
with Death and his great army.
One who dwells thus, ardent (ātāpī),
untiring by day and by night—
it is that one, truly, whom the peaceful sage calls
"one who has one auspicious night."
Who, then, might analyze in detail the meaning of this summary recited in brief by the Blessed One, whose meaning he did not analyze in detail?' Then, venerable sir, this occurred to us: 'This venerable Mahākaccāna is praised by the Teacher and esteemed by his wise companions in the holy life; and the venerable Mahākaccāna is capable of analyzing in detail the meaning of this summary recited in brief by the Blessed One, whose meaning he did not analyze in detail. Suppose we were to approach the venerable Mahākaccāna and question him about this matter.' Then, venerable sir, we approached the venerable Mahākaccāna and questioned him about this matter. And to us, venerable sir, the meaning was analyzed by the venerable Mahākaccāna in these ways, with these words, with these phrases."
