The teaching in one sentence
The same four are also powers.
Faculty and power
The distinction the tradition draws is this. An indriya governs: within its own domain it is what is in charge. A bala is unshakeable: it cannot be overthrown by its opposite.
So faith as a faculty is what decides where a person commits; faith as a power is faith that doubt cannot dislodge. Energy as a faculty is what keeps a person at something; energy as a power is energy that laziness cannot break. Mindfulness against forgetfulness, immersion against distraction.
That is a commentarial formulation and should be labelled as one. The suttas give the two names and, in the great majority of cases, the same four or five items under each, without defining the difference. What the later tradition supplied is a way of accounting for why both terms exist.
What can be said from the texts alone is weaker and still useful: the collection thought the same items were worth two names, and it consistently keeps both.
Why a peyyāla is not the right description here
AN 4.141 to AN 4.145 gave one teaching under five near-synonyms for light, and this reading guide called that a filing operation. It would be easy to say the same thing here and it would be wrong.
Ābhā and pabhā are ordinary words that overlap. Indriya and bala are technical terms with separate places in the standard list of the things that lead to awakening — the five faculties and the five powers are two of the seven sets, listed separately, and a scheme that treated them as synonyms would not have kept both.
The test is whether anything elsewhere depends on the distinction, and here something does. That is the difference between a synonym-series and a genuine pair, and it is worth having a rule for, because the Aṅguttara contains a great many of both.
The three discourses that follow
AN 4.153, AN 4.154, and AN 4.155 also announce four powers, and none of them gives this list. They give: wisdom, energy, blamelessness, inclusiveness; then mindfulness, immersion, blamelessness, inclusiveness; then reflection, development, blamelessness, inclusiveness.
So bala is being used for two different things in one chapter. AN 4.152 is the power-version of the faculties. AN 4.153 to AN 4.155 are a separate set with a fixed second half.
A reader going straight through will meet four consecutive discourses that all begin ‘there are these four powers’ and give three different lists, and it is worth being told in advance rather than discovering it as a confusion.
It is also worth noticing that nothing in the text marks the change. The compilers filed everything called a set of four powers together and left the reader to sort it out.
What the second name is for, practically
Setting aside the technical question, the pairing has a use.
A quality one has is not the same as a quality one can rely on. Most people have some faith, some energy, some mindfulness, and some capacity for collection; far fewer have any of them in a form that survives contact with its opposite.
The two words name that difference. Whether or not the commentarial definition is the original one, it identifies something real, and the identification is the reason to read AN 4.151 and AN 4.152 as a pair rather than as a duplicate.
The diagnostic question changes accordingly. AN 4.151 asks whether the four are present. AN 4.152 asks what happens to each of them under pressure.
Where it sits
Second of the chapter’s ten and second of its five short filings.
Three more discourses on powers follow, and then the chapter breaks into cosmology at AN 4.156 and into its substantial run at AN 4.157.
The title given to this discourse in the Pāli is Saddhābalasutta, after its first item, which is the usual convention: a discourse takes its name from the first thing in it.
