[552] Then, soon after the Blessed One had departed, those bhikkhus considered thus: "Friends, the Blessed One, having recited this summary in brief without explaining its meaning in detail, has risen from his seat and entered his 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.
And whoever sees with insight each presently arisen dhamma
just where it occurs —
having known that which is unfaltering, unshakable,
let him cultivate it.
Today itself the effort (ardour) must be made;
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 he, indeed, whom the peaceful sage declares
"one who has an auspicious night (bhaddekaratta)."'
Who, then, could explain in detail the meaning of this summary that the Blessed One recited in brief without explaining its meaning in detail?"
Then those bhikkhus considered thus: "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 explaining in detail the meaning of this summary that the Blessed One recited in brief without explaining its meaning in detail. Suppose we were to approach the Venerable Mahākaccāna and, having approached, question the Venerable Mahākaccāna about this matter."
