AN8.63 — Saṅkhittasutta
Then a certain disciple approached the Blessed One... and having sat to one side, he said to the Blessed One: Venerable sir, may the Blessed One teach me the Dhamma in brief, so that having heard the Blessed One's Dhamma, I may dwell alone, withdrawn, diligent, ardent, and resolute.
Some foolish men here ask me for this. And when the Dhamma is spoken, they think they should follow me.
Please teach me, venerable sir, the Dhamma in brief. May the Blessed One teach me the Dhamma in brief. Perhaps I may understand the meaning of the Blessed One's words, perhaps I may become an heir to the Blessed One's words.

Then that disciple, having been advised by the Blessed One with this advice, rose from his seat, paid homage to the Blessed One, and departed, keeping him on his right.
Then that disciple, secluded, diligent, ardent, and resolute, not long after, realized for himself with direct knowing, here and now, the ultimate goal of the holy life for which sons of good family rightly go forth from the household life into homelessness, having attained it, he dwelled in it.
He understood: Birth is destroyed, the holy life has been lived, what had to be done has been done, there is no more of this state of being.
And that disciple became one of the arahants.
