The teaching in one sentence
The same teaching as AN 4.141, filed one last time, under the word for a lamp.
A noun among adjective-nouns
The grammatical shift is small and the effect is not. To speak of the moon’s brightness is to speak of something the moon has. To call the moon a lamp is to speak of what it is for.
Pajjota comes from a root meaning to blaze, and the ordinary sense of the word is a light you can point at — the oil lamp in a room, a torch carried down a road. It is a household object.
Applied to the sun and moon it makes them instruments: two very large lamps, lit for the benefit of whatever is under them. Applied to wisdom it makes wisdom an instrument too, and that is a different figure from the one the series started with.
None of this is stated. The discourse is the same five lines. The shift is entirely in the head-word, which is exactly the sort of thing a synonym-series makes visible and a single discourse would not.
The lamp that goes out
A lamp is the tradition’s standing image for something that ends when its fuel ends, and the vocabulary of the goal is built on it: nibbāna is the going out of a flame.
The resonance is available and it should be handled carefully. AN 4.145 does not make that move. It calls wisdom the best of four lamps and stops, and reading the extinguishing of a lamp into a discourse that is about which lamp is brightest is reading in.
What can be said without straining is that the series has now placed wisdom in a category of things that burn while they are fed, and left it there without comment. The three physical lamps in the list all go out. The discourse does not say whether the fourth does.
That silence is more interesting than any answer that could be supplied for it, and a teacher is better off pointing at it than filling it.
The series, complete
Five discourses, five words, one teaching. Counting them together: four items each time, twenty item-mentions, five superlatives, and not one sentence of explanation anywhere in the sequence.
That is what a peyyāla looks like from the outside, and the Fours contain far larger ones. The collection ends in two abridged blocks in which sets are crossed with sets to generate hundreds of nominal discourses, and by comparison this chapter’s five are almost conversational.
The pedagogical value of a small one is that a reader can hold the whole thing at once. Anyone who has read AN 4.141 to AN 4.145 in order knows what the mechanism is and will recognize it at any scale afterward.
It is also worth saying what the mechanism costs. Five separate numbered discourses which are one teaching inflate every count anyone makes of the collection, and a reader who takes the Aṅguttara’s discourse-count at face value is counting filings, not teachings.
What the four lights add up to
Across the five filings the list has been given twenty times without a single word about why the moon, the sun, and fire were chosen and not, say, lightning or a jewel.
The likeliest answer is the plainest. These are the three lights a person in that time and place lived by: the one that governs the night, the one that governs the day, and the one you make when neither is available. Between them they cover every hour a human being is awake.
Read that way the list is not a set of impressive things but a complete inventory of ordinary illumination, and adding wisdom to it is a claim that something else belongs in that inventory — not above it, in it.
That is a smaller and better claim than the metaphor usually gets stretched to carry, and it is the one the five discourses actually make.
Where it sits
Fifth and last of the filings, halfway through the chapter.
AN 4.146 and AN 4.147 follow with the four times — for listening, for discussing, for serenity, for discernment — and the second of those pairs the list with a simile of rain filling a mountain down to the ocean.
Then two discourses on speech, and then AN 4.150 closes the chapter by naming ethics, immersion, wisdom, and freedom the heartwood.
