The teaching in one sentence
The scale of the world is stated in three multiplications, and the last word of the discourse is about somebody’s confidence rather than about the cosmos.
Asking three times
The question is asked and refused twice with the same reply: he was a disciple, Ānanda. Realized Ones are immeasurable. That is not evasion so much as a category objection — the comparison Ānanda is trying to make has no upper term.
On the third asking the Buddha changes tack and asks whether Ānanda has heard of a thousandfold lesser world system, and Ānanda gives the formula that invites teaching: now is the time, Blessed One! The same phrase Sāriputta uses in AN 3.33.
Asking three times is a recognized pattern in the canon and it usually marks a request as serious rather than idle. It is worth noticing that here it works — persistence is rewarded, where in AN 3.60 Ānanda’s three askings of Saṅgārava produced only silence.
Three scales
A galaxy — a thousandfold lesser world system — contains a thousand moons, a thousand suns, a thousand Mount Merus, a thousand of each of the four continents, four thousand oceans, four thousand great kings, and a thousand of each heaven up through the Brahmā realm.
A thousand of those is a galactic cluster, a millionfold middling world system. A thousand of those is a galactic supercluster, a billionfold great world system.
This is the scheme that entered Chinese as 三千大千世界, the thousand-cubed great thousand world — a phrase any reader of Mahāyāna sūtras has met dozens of times, usually without being told that it names a specific arithmetic rather than a poetic immensity. Anyone who has read the Lotus or the Diamond Sūtra has been counting these.
A word about the translation is owed here. Sujato renders the three as galaxy, galactic cluster, and supercluster, which is an interpretive choice: the Pāli says cūḷanikā lokadhātu, a lesser world element, and so on. The rendering makes the scheme vivid for a modern reader and it also imports a modern cosmology the text does not have. A class should be told this, and told that the underlying claim — a thousand of these, a thousand of those, and a thousand again — is unaffected either way.
The answer, and the method
If he wished, Ānanda, a Realized One could make his voice heard throughout a galactic supercluster, or as far as he wants. Then Ānanda asks how, and gets a two-step procedure: fill the whole system with light; and when beings see the light, project the call so they hear it.
The light comes first. Whatever one makes of the claim, the sequence is worth noticing: the voice does not arrive unannounced. Something is made visible, attention is drawn, and then the sound is sent. It is a description of how anybody gets heard at scale.
The passage sits oddly with AN 3.60, twenty discourses earlier, where the demonstration of psychic power was ranked last of three and let stand as such. The Threes evidently did not regard the powers as embarrassing; they regarded them as ineffective for convincing anybody, which is a different objection and is not contradicted here. Nobody in this discourse is being convinced of anything.
Udāyī, and the last paragraph
Ānanda says: I’m so fortunate, so very fortunate, to have a teacher with such power and might!
And Udāyī says: what is it to you, Reverend Ānanda, if your teacher has such power and might?
That is a hard sentence and the discourse does not explain it. It can be read as a rebuke — your teacher’s attainment is not yours — which would be a defensible point badly timed, and Udāyī elsewhere in the canon is often the one who says the tactless thing.
The Buddha’s reply is the strangest part of the discourse. Not so, Udāyī, not so! If Ānanda were to die while still not free of greed, he would rule as king of the gods for seven lifetimes, or as king of the Black Plum Tree Land for seven lifetimes, because of the confidence of his heart. However, Ānanda will be fully extinguished in this very life.
So the defense of Ānanda is that his confidence in his teacher is itself worth an enormous amount — and then that the calculation does not apply, because he will finish. Two answers to Udāyī, and the second cancels the first.
It is also a prediction made about a named living person in his presence, which the canon does not do lightly, and it is the answer to the question Udāyī asked: what is it to you? It is this much.
Using it
Teach the cosmology for the Chinese connection, which is immediate and useful: a class that has read 三千大千世界 in a Mahāyāna sūtra can be shown where the phrase comes from and what it counts.
Teach the last paragraph for the human material. A student expresses delight in his teacher, a colleague makes a cutting remark about it, and the teacher defends the student by putting a value on the delight itself. Very little in the canon is more recognizable than that exchange, and it is preserved without any comment on who was right.

§1Then Venerable Ānanda went up to the Buddha, bowed, sat down to one side, and said to him: “Sir, I have heard and learned this in the presence of the Buddha: ‘Ānanda, the Buddha Sikhī had a disciple called Abhibhū. Standing in the realm of divinity, he could make his voice heard throughout the thousandfold galaxy.’ I wonder how far a Blessed One, a perfected one, a fully awakened Buddha can make their voice heard?” “He was a disciple, Ānanda. Realized Ones are immeasurable.”
§2For a second time …
§3For a third time, Ānanda said to the Buddha: “… I wonder how far a Blessed One, a perfected one, a fully awakened Buddha can make their voice heard?” “Ānanda, have you heard of a thousandfold lesser world system, a galaxy?” “Now is the time, Blessed One! Now is the time, Holy One! Let the Buddha speak. The mendicants will listen and remember it.” “Well then, Ānanda, listen and apply your mind well, I will speak.” “Yes, sir,” Ānanda replied. The Buddha said this:
Three scales
§4“Ānanda, a galaxy extends a thousand times as far as the moon and sun revolve and the shining ones light up the quarters. In that galaxy there are a thousand moons, a thousand suns, a thousand Sinerus king of mountains, a thousand Black Plum Tree Lands, a thousand lands west of Godāvarī, a thousand lands north of Kuru, a thousand lands east of Videha, four thousand oceans, four thousand great kings, a thousand realms of the gods of the four great kings, a thousand realms of the gods of the thirty-three, of the gods of Yama, of the joyful gods, of the gods who love to create, of the gods who control what is created by others, and a thousand realms of divinity. This is called a thousandfold lesser world system, a ‘galaxy’.
§5–6A world system that extends for a thousand galaxies is called a millionfold middling world system, a ‘galactic cluster’. A world system that extends for a thousand galactic clusters is called a billionfold great world system, a ‘galactic supercluster’.
How far, and how
§7If he wished, Ānanda, a Realized One could make his voice heard throughout a galactic supercluster, or as far as he wants.”
§8“But how would the Buddha make his voice heard so far?” “First, Ānanda, a Realized One would fill the galactic supercluster with light. When sentient beings saw the light, the Realized One would project his call so that they’d hear the sound. That’s how a Realized One could make his voice heard throughout a galactic supercluster, or as far as he wants.”
What is it to you?
§9When he said this, Venerable Ānanda said, “I’m so fortunate, so very fortunate, to have a teacher with such power and might!” When he said this, Venerable Udāyī said to Venerable Ānanda, “What is it to you, Reverend Ānanda, if your teacher has such power and might?” When he said this, the Buddha said to Venerable Udāyī, “Not so, Udāyī, not so! If Ānanda were to die while still not free of greed, he would rule as king of the gods for seven lifetimes, or as king of the Black Plum Tree Land for seven lifetimes, because of the confidence of his heart. However, Ānanda will be fully extinguished in this very life.”
