Light

Ālokasutta — Ābhāvagga — the fifteenth chapter of the Fours

Northern parallel
The awakening formula this word closes is shared across the collections; this reading guide does not assert a specific matching sutra number for this discourse
Difficulty
★★☆☆☆ — five lines, and the word they turn on carries more weight than the discourse uses

Why this discourse

The third filing of the same teaching, and the one word of the five with a career of its own. Āloka is not built on a root meaning to shine; it is built on the root for seeing, and it is the last of the five things the first sermon says arose: vision arose, knowledge arose, wisdom arose, realization arose, light arose.

Reading guide

The teaching in one sentence

The same teaching as AN 4.141, filed under the word for light-that-lets-you-see.

A word from the root for seeing

The other four words in the series describe what a source does. Āloka describes what an eye is given. Its root is lok-, to look, and the word means daylight, illumination, the condition under which things are visible.

That makes it the least metaphorical of the five when it is applied to wisdom, and also the most. Least, because saying ‘the light of wisdom’ with this word says wisdom is the condition under which something becomes visible, which is close to a plain description of what wisdom does. Most, because nothing about wisdom emits anything.

The compound with which the word is most often met in practice is ālokasaññā, the perception of light — a meditation instruction given for drowsiness, in which a practitioner attends to the perception of light so that the mind stays clear. That is a technique, and it is not what this discourse is about, but it is why the word will sound familiar to anyone who has sat through a nod.

‘Light arose’

The first sermon closes each turn of its account with a five-fold formula: cakkhuṁ udapādi, ñāṇaṁ udapādi, paññā udapādi, vijjā udapādi, āloko udapādi. Vision arose, knowledge arose, wisdom arose, realization arose, light arose.

Two things in that list are worth holding against AN 4.143. The first is that paññā and āloka both appear in it, as separate items — so the awakening formula does not treat wisdom and light as the same thing.

The second is that āloka comes last. Whatever the sequence in that formula is doing, light is where it ends, and it ends there in the account of the moment the tradition dates itself from.

AN 4.143 puts the two words together into one compound, paññāloko, and calls it the best of four. It is a much smaller statement than the first sermon’s, and it is made of the same two pieces. This reading guide does not claim the compound was built with the formula in mind; it notes that the vocabulary is shared and that a reader who knows one will hear it in the other.

What a light does that a fire does not

Since this is the word for illumination rather than for emission, it is the filing under which the comparison in the list makes the most sense.

Moonlight, sunlight, and firelight are all conditions under which things can be seen, and they differ in how much they show and for how long. Ranking wisdom above them is then a claim about scope: more is visible by it, and it does not stop.

That is as far as the discourse goes, and it is worth not going further. It does not say what becomes visible. It does not say the other three lights are false, or unnecessary, or that a person with wisdom needs no lamp.

A reader who wants the content supplied has to go elsewhere in the collection, and the chapter provides it seven discourses later. AN 4.150 names ethics, immersion, wisdom, and freedom as the heartwood, which is the same word paññā doing structural work rather than metaphorical work.

The middle of a series

Third of five, and the point at which a reciter is deepest into the repetition.

It is worth saying something about what that felt like, because it is easy to read a peyyāla as a list on a page and forget that it was a thing people did with their voices. Five discourses of five lines each, sharing every word but one, recited in sequence: the effect is not tedium but emphasis, and the single varying word stands out precisely because everything around it does not move.

The technique is the same one AN 4.123 to AN 4.126 used with the absorptions and the immeasurables, at a larger scale and with a doctrinal point riding on the variation. Here there is no doctrinal point riding on it. There is only the teaching, said five times, so that it cannot be lost.

Where it sits

Third of the five filings and third of the chapter’s ten. Two more filings follow, and then the chapter turns to the four times, to speech, and to the heartwood.

The next, AN 4.144, is the one filing in the series that needs a word of caution, because its head-word names something practitioners report seeing.

The one after, AN 4.145, closes the series by turning light into an object.

Key terms

āloka — “light” — from lok-, to look; the condition under which things are visible, rather than what a source emits.
paññāloka — “the light of wisdom” — the compound this discourse ranks first, built from two words that stand separately in the awakening formula.
ālokasaññā — “perception of light” — a standard instruction against drowsiness; not this discourse’s subject, but the reason the word sounds familiar.
udapādi — “arose” — the verb repeated five times in the first sermon’s closing formula, of which āloko udapādi is the last.
vijjā — “realization”, true knowledge — the fourth item of that formula, standing between wisdom and light.

The text

The discourse in full: four lights, and which is best. Translation: Bhikkhu Sujato (CC0, SuttaCentral).

Four lights

§1“Mendicants, there are these four lights. What four? The lights of the moon, sun, fire, and wisdom. These are the four lights. The best of these four lights is the light of wisdom.”
