[317] Then the Venerable Ānanda, when that night had passed, having dressed in the morning and taken his bowl and robe, with the bhikkhu Cetaka as his attendant ascetic (pacchāsamaṇa), approached the residence of Subha the brahmin student (māṇava), Todeyya's son; and having approached, he sat down on the seat that had been prepared.
Then Subha the brahmin student, Todeyya's son, approached the Venerable Ānanda; having approached, he exchanged greetings with the Venerable Ānanda, and when the courteous and memorable talk was concluded, he sat down to one side. Seated to one side, Subha the brahmin student, Todeyya's son, said this to the Venerable Ānanda: "The worthy Ānanda was for a long time the attendant of that worthy Gotama, one who moved in his presence, one who lived close by him. The worthy Ānanda would know of which dhammas that worthy Gotama spoke in praise, and in which he caused this populace to undertake them, to become settled in them, and to become established in them. Of which dhammas, worthy Ānanda, did that worthy Gotama speak in praise, and in which did he cause this populace to undertake them, to become settled in them, and to become established in them?"
The Three Noble Aggregates
The Noble Aggregate of Virtue
"Young brahmin, it was of three aggregates (khandha) that the Blessed One spoke in praise, and it was in these that he caused this populace to undertake them, to become settled in them, and to become established in them. Which three? The noble aggregate of virtue (sīlakkhandha), the noble aggregate of concentration (samādhikkhandha), and the noble aggregate of wisdom (paññākkhandha). Young brahmin, it was of these three aggregates that the Blessed One spoke in praise, and it was in these that he caused this populace to undertake them, to become settled in them, and to become established in them."
