Cāga as a Faculty of Stream-Entry

I. Introduction

For many Western Buddhist readers, the word merit arrives with a vague unease. It sounds too much like accounting, too much like transaction, too much like the commercial grammar by which one puts in A and expects to receive B. Among more sophisticated readers, this kind of language has been quietly retired from Western Buddhist discourse: mindfulness courses don't talk about merit, meditation teachers don't talk about merit, even in Mahāyāna academic settings merit appears mostly when the textual material forces it, rarely in the speaker's own voice. In the English-speaking dharma scene, "merit" is a term politely avoided.

But an awkward fact hangs over this avoidance. In the earliest layer of Pāli texts, one of the terms that can occupy the fourth slot in the standard definition of a stream-enterer (sotāpanna) — the fourth sotāpattiyaṅga, the fourth "limb of stream-entry" — is precisely the word later translated as "giving" in English and woven into the language of merit throughout the later tradition. That word is cāga. If cāga were really just "giving with meritorious intent," how could it stand, in the earliest formulas, alongside the ethical conduct of a noble one (ariyakantehi sīlehi) as one of four inner marks that identify a being who has entered the stream? If giving is a transaction, how could it simultaneously be a fruit?

The tension is not a small problem. Resolved, it shows us where early Buddhism actually located the act of giving; left unresolved, the entire teaching on giving reads as a religiously sanctioned theory of spiritual investment — you put capital into the field of merit, expecting to recoup stock in the heavens — and this is exactly the most persistent Western misreading of the Chinese Buddhist tradition, a misreading which, to be fair, is not always unjustified by actual conditions on the ground.

This paper's thesis: cāga is not a merit-accumulator. It is a faculty of path (sotāpattiyaṅga in the technical sense) — a cultivation function with independent structural standing, of equal rank with sīla and paññā, irreducible to any transactional frame.

The argument proceeds in five moves. First, three adjacent suttas in the Puññābhisandavagga of the Saṃyutta Nikāya (SN 55.31, 55.32, 55.33) rotate three different qualities through the fourth slot of the four-limb formula: sīla (ethical conduct), cāga (letting-go), paññā (wisdom). This is not the binary substitution discussed in P01 (where sīla and cāga were shown to hold equal weight); it is a triple rotation — a structural slot opened from three angles. Second, these three rotating qualities are not isolated candidates. They are three of the five qualities recorded at SN 55.21 and AN 6.25 as the foundational inner structure of the noble disciple (saddhā / sīla / suta / cāga / paññā); the four-limb rotation is what happens when the five-virtue foundation is compressed into teaching form. Third, SN 55.39 presents the Sakyan laywoman Kāḷigodhā self-declaring stream-entry by way of the cāga formula, with the Buddha's immediate approval — empirical demonstration that cāga as a limb of stream-entry is not doctrinal hypothesis but a cultivation function available to direct verification. Fourth, SN 55.40 reveals that even possession of all four limbs does not of itself set in motion the causal sequence of gladness, rapture, tranquility, bliss, concentration, and the manifestation of dhammas; that sequence requires heedfulness (appamāda) to activate. Fifth, a dual-track reading of the Chinese Saṃyuktāgama (T0099《雜阿含經》Saṃyukta-āgamaT2, No. 99Guṇabhadra (Liu Song, ca. 435 CE)View on CBETA online reader ↗, fascicle 33) shows that the Chinese translation tradition systematically softens the cāga track: the Buddha's definitive ruling on the four limbs takes only the sīla track (sūtra 935), and the "cāga" position in the five-virtue lists is repeatedly replaced with "giving" (施, sūtras 930, 931, 932). The softening itself — not arbitrary, not incompetent, but selective — retrospectively confirms the doctrinal tension this paper is excavating from the Pāli side.

Joined up, these five moves land on a single claim: cāga in early Buddhism is a direct countermeasure to the root construction of "mine" that drives the saṃsāric cycle. Other wholesome mental factors work on downstream operations (patience handles the emotional response, energy handles motivation, loving-kindness handles interpersonal bias); only cāga works at the root, on the mine-making operation itself. That is why, among the many wholesome factors, it is cāga — and not patience, not energy, not loving-kindness — that is selected into the stream-entry candidate sequence. Stream-entry is the first structurally irreversible breach in the saṃsāric cycle; its inner marks must point at the root construction.

Read this way, the word "merit" does not need to be defended — it simply relocates. Merit is not the goal of giving; it is something giving produces as a side-effect, the way a walker's shoes wear on the soles. No one walks in order to wear out their soles. Something real is happening; meritorious fruit is one of its traces. Read in reverse: Western readers' unease about merit-language is not prejudice. It is a legitimate refusal of the transactional reading of giving. This paper's work is to extract cāga from that transactional reading and return it to its proper position — a limb of the path.

II. Canonical Foundation

The evidence runs in two registers. Register A is the discourse layer (the sutta material), presented in four groups corresponding to the four strata of argument. Register B is the commentarial layer, anchored in the Visuddhimagga's Cāgānussati-niddesa. In keeping with the NIAN-A discipline of this volume, every Pāli citation is paired with the corresponding Chinese canonical reference where one exists, so that readers can see the different shapes the cāga teaching took in the two traditions.

2.1 Register A: Discourses (Pāli with Chinese parallels)

Group 1: The triple rotation in the fourth limb

The Puññābhisandavagga ("Chapter on the Overflows of Merit") of the Saṃyutta Nikāya is composed of ten adjacent suttas. Its opening three (SN 55.31, 55.32, 55.33) share an identical structural frame: "Mendicants, there are these four overflows of merit, overflows of the wholesome, nutriments of bliss. What four?" — followed by a listing of four limbs. The first three limbs are constant across all three suttas: unshakable confidence (aveccappasāda) in the Buddha, the Dhamma, and the Saṅgha. The fourth limb differs in each:

• SN 55.31 Paṭhamapuññābhisandasutta¹: the fourth limb is "accomplishment in the noble's ethical conduct" (ariyakantehi sīlehi samannāgato — the conduct that is beloved of the noble, unbroken, unflawed, unblemished, unblotched, conducing to concentration).
• SN 55.32 Dutiyapuññābhisandasutta²: the fourth limb becomes cāga — "the noble disciple dwells at home with a mind freed from the stain of stinginess, with letting-go loosened (muttacāgo), with hand washed clean (payatapāṇi), delighting in relinquishment (vossaggarato), responsive to those who request (yācayogo), delighting in giving and sharing (dānasaṁvibhāgarato)."
• SN 55.33 Tatiyapuññābhisandasutta³: the fourth limb becomes paññā — "the noble disciple is wise, endowed with wisdom directed to the arising and passing away, noble, penetrative, leading to the complete destruction of suffering" (udayatthagāminiyā paññāya samannāgato ariyāya nibbedhikāya sammā dukkhakkhayagāminiyā).

Three adjacent suttas, identical structural frame, with only the fourth position varying. This is not a variant of a single text. It is an editorial decision by the compilers of the Puññābhisandavagga to treat "the fourth position of the four limbs" as a structurally rotatable slot, filled across three consecutive suttas with sīla, cāga, and paññā in turn.

P01 cited the sīla ↔ cāga swap of SN 55.31/55.32 as evidence that cāga holds equal weight with sīla within the candidate field of three terms dāna / cāga / yāga. With SN 55.33 brought into view, the structure completes: the fourth position is a triple rotation (sīla / cāga / paññā), not a binary swap. It is "one window that can be opened from three angles," with the angle of approach determined by the teaching context.

Group 2: The second witness — Kāḷigodhā and Nandiya

Two further suttas in the same vagga (SN 55.39, SN 55.40) extend the cāga track from the Buddha's general teaching to a specific encounter, and from the question "what are the limbs?" to the question "what happens when the limbs are present?"

• SN 55.39 Kāḷigodhāsutta⁴: the Buddha, visiting Kapilavatthu, goes to the home of the Sakyan laywoman Kāḷigodhā for alms and teaches her the four limbs in the cāga variant — unshakable confidence in the Three Jewels, and "dwelling at home with a mind freed from the stain of stinginess, with letting-go loosened, with hand washed clean, delighting in relinquishment, responsive to those who request, delighting in giving and sharing." Kāḷigodhā responds: "Venerable sir, these four limbs of stream-entry that the Blessed One has taught — these qualities are present in me, and I am seen to possess them." She enumerates her own unshakable confidence in Buddha, Dhamma, Saṅgha, then addresses the fourth limb in her own words: "In our household, whatever is a fit thing to be given (yaṁ kho pana kiñci kule deyyadhammaṁ), all of it, without any discrimination (sabbaṁ taṁ appaṭivibhattaṁ), is shared with the virtuous and those of good qualities (sīlavantehi kalyāṇadhammehī)." The Buddha's response is short and formal: "It is a gain for you, Godhā, a great gain for you, Godhā. You have declared the fruit of stream-entry yourself (sotāpattiphalaṁ tayā, godhe, byākatan)."

• SN 55.40 Nandiyasakkasutta⁵: in the same setting, the Sakyan Nandiya asks the Buddha: what kind of practitioner is a noble disciple who does not possess the four limbs? The Buddha answers: such a person is no noble disciple; he stands among the ordinary folk. But the Buddha then extends the teaching a further layer. Even with the four limbs, noble disciples divide into two types: the heedless-dweller (pamādavihārī) and the heedful-dweller (appamādavihārī). The heedless-dweller, satisfied with his four limbs (tena santuṭṭho), ceases further exertion in daytime solitude and nighttime meditation; gladness does not arise (pāmojja), rapture does not arise (pīti), tranquility does not arise (passaddhi), bliss is not attained (sukha), the mind does not concentrate (cittaṁ na samādhiyati), dhammas do not become manifest (dhammā na pātubhavanti). The heedful-dweller, by contrast — not satisfied, still pressing forward — sets the whole sequence in motion.

These two suttas supply two crucial supplements to the cāga teaching. Kāḷigodhā's case shows that cāga-track stream-entry can be self-verified and self-declared by a laywoman, and that the Buddha does not require advanced meditative credentials before she is permitted to make the declaration. This is the most direct evidence that cāga is a cultivation function available to empirical demonstration — not a technical term but a reality a noble disciple can observe in herself. Nandiya's case shows that possessing the four limbs (whether the fourth is sīla, cāga, or paññā) is not the end of the path but its beginning. The causal chain from gladness through the manifestation of dhammas activates only under heedfulness; under heedlessness, the chain remains dormant even with all four limbs in place. Joined together, the two suttas answer the question what kind of function is cāga: it is a faculty that can be verified, and it is a configuration that requires continuous activation through heedfulness.

Group 3: The five-virtue foundation — the substrate beneath the four-limb rotation

The triple rotation in the fourth limb is possible because beneath it lies a fuller structure: the five-virtue foundation (saddhā / sīla / suta / cāga / paññā — faith, ethical conduct, learning, letting-go, wisdom). This five-virtue formula surfaces in several key suttas with distinct framings.

• SN 55.21 Paṭhamamahānāmasutta⁶: Mahānāma, troubled by the crowded streets of Kapilavatthu and nearly trampled by rogue elephants and horses on his way home, asks the Buddha where he would be reborn if he died in such a moment. The Buddha replies: "If anyone's mind has been long perfumed by faith, perfumed by ethical conduct, perfumed by learning, perfumed by letting-go (cāgaparibhāvitaṁ cittaṁ), perfumed by wisdom, though his body be consumed by crows, hawks, and vultures, his mind rises, tends upward, moves to the higher." The Buddha closes with the simile of a ghee-jar broken in a pool of water: the broken shards sink, but the ghee and oil rise to the surface. This is the five-virtue foundation in its complete, pre-compressed form.

• AN 6.25 Anussatiṭṭhānasutta⁷: the Buddha teaches the six topics for recollection (cha anussatiṭṭhānāni); the fifth is cāgānussati — the noble disciple recollects their own letting-go, using the same muttacāga formula quoted above. The sixth topic, recollection of the deities (devatānussati), then brings the five-virtue foundation back into explicit view: the noble disciple recalls the deities "by virtue of their faith, their ethical conduct, their learning, their letting-go, their wisdom" and reflects "such faith, ethical conduct, learning, letting-go, and wisdom are found in me also." The symmetry — the deities possess these five, and so do I — shows that the five-virtue formula is not an ad-hoc combination but an integral inner structure shared by all accomplished beings.

• AN 11.11 Paṭhamamahānāmasutta⁸: the Buddha, teaching the same Mahānāma, lays out eleven dwellings of mind. The five spiritual faculties (saddhā / vīriya / sati / samādhi / paññā) form the base, and the six recollections — including cāgānussati — are built on top of them. The cāgānussati formula is identical to the one at AN 6.25. This sutta reveals the relation between foundation and practice: the five faculties are capacities, the six recollections are applied meditation objects that deploy those capacities. Cāgānussati is cāga set up as a meditation object for the faculty structure to work on.

Synthesizing these three suttas: the triple rotation in the fourth limb (sīla / cāga / paññā) is not a competition among three accidental candidates. It is what happens when the five-virtue foundation is compressed for teaching use — the first three positions absorb saddhā into unshakable confidence in Buddha / Dhamma / Saṅgha, suta (learning) drops out because it is a conductive rather than foreground virtue, and the fourth position surfaces whichever of the three remaining virtues best suits the teaching moment. This explains why sīla, cāga, and paññā can rotate while saddhā and suta cannot: saddhā has already been absorbed into the first three limbs, and suta is a transmission virtue that enables the others but does not itself serve as a visible mark.

Group 4: The systematic softening in the Chinese

NIAN-A dual-track discipline requires a parallel reading of the Chinese canonical material. The Saṃyuktāgama (Zá Āhán Jīng, T0099《雜阿含經》Saṃyukta-āgamaT2, No. 99Guṇabhadra (Liu Song, ca. 435 CE)View on CBETA online reader ↗), translated by Guṇabhadra (劉宋求那跋陀羅) in the mid-fifth century CE, is the Chinese counterpart closest in structure to the Saṃyutta Nikāya's Book 55. Its fascicle 33 contains the Mahānāma dialogue cluster (sūtras 927–936, ten suttas) covering material corresponding to SN 55.21, 55.22, 55.31–33, 55.37, 55.39, and 55.40 — but on the question of the cāga track, the Chinese shows a systematic divergence from the Pāli.

• T0099《雜阿含經》Saṃyukta-āgamaT2, No. 99Guṇabhadra (Liu Song, ca. 435 CE)View on CBETA online reader ↗ sūtra 935⁹: a Sakyan named Shatou (釋氏沙陀) and Mahānāma dispute over how many qualities constitute stream-entry. Shatou says three (the three unshakable confidences); Mahānāma says four (the three plus "accomplishment in noble ethical conduct"). They take the question to the Buddha, who rules in Mahānāma's favor: 「是故當知四法成就須陀洹：於佛不壞淨、於法不壞淨、於僧不壞淨、聖戒成就。如是受持。」("Therefore you should know: stream-entry is accomplished by these four qualities — unshakable faith in the Buddha, unshakable faith in the Dhamma, unshakable faith in the Saṅgha, and accomplishment in noble ethical conduct. Thus you should uphold it.") This is the Chinese tradition's definitive ruling on the four limbs, and it takes only the sīla track. The Chinese tradition contains no parallel to SN 55.32 or SN 55.39 in which the fourth limb appears as cāga.

• T0099《雜阿含經》Saṃyukta-āgamaT2, No. 99Guṇabhadra (Liu Song, ca. 435 CE)View on CBETA online reader ↗ sūtra 930¹⁰: the Chinese parallel to SN 55.21 (Mahānāma's deathbed worry). The Pāli's five-virtue list "perfumed by faith, ethical conduct, learning, letting-go, wisdom" appears in Chinese as 「戒、施、聞、慧所熏」("perfumed by ethical conduct, giving, learning, wisdom") — the Pāli cāga is replaced with the Chinese 施 (shī, giving).

• T0099《雜阿含經》Saṃyukta-āgamaT2, No. 99Guṇabhadra (Liu Song, ca. 435 CE)View on CBETA online reader ↗ sūtra 931¹¹: the Chinese parallel to AN 11.11 (the six recollections as practice). The object of the fifth recollection is replaced from cāga to 施事 ("the matter of giving"). The six-recollection series is preserved as a whole, but the inner object of the cāga-recollection has been relocated to the behavior-level dāna.

• T0099《雜阿含經》Saṃyukta-āgamaT2, No. 99Guṇabhadra (Liu Song, ca. 435 CE)View on CBETA online reader ↗ sūtra 932¹²: in a further Mahānāma dialogue, the five-virtue foundation appears as 「正信為主，戒具足、聞具足、施具足、慧具足為本」 ("taking right faith as foremost, rooted in the accomplishment of ethical conduct, of learning, of giving, and of wisdom") — once again, the fourth position uses 施 rather than 捨.

The pattern is not universal softening. The Chinese tradition does preserve the cāga track in bounded pockets:

• T0099《雜阿含經》Saṃyukta-āgamaT2, No. 99Guṇabhadra (Liu Song, ca. 435 CE)View on CBETA online reader ↗ sūtra 927¹³: the Buddha teaches Mahānāma the lay practitioner's five accomplishments (優婆塞五具足) — faith, ethical conduct, learning, letting-go (捨), wisdom. The "accomplishment in letting-go" (捨具足) is defined as "one who, enmeshed in the stain of stinginess, is liberated in mind from that stain, dwells at the non-home, practices liberated giving, diligent giving, constant giving, delight in relinquishing wealth, equal giving (解脫施、勤施、常施、樂捨財物、平等布施)." The category "letting-go" is structurally preserved here, but the five marker-words inside it — Pāli's muttacāga / payatapāṇi / vossaggarato / yācayogo / dānasaṁvibhāgarato — have been translated into a Chinese set whose operational language is heavily dāna-inflected (yācayogo has no visible counterpart at all).

• T0099《雜阿含經》Saṃyukta-āgamaT2, No. 99Guṇabhadra (Liu Song, ca. 435 CE)View on CBETA online reader ↗ sūtra 931¹¹ (same sūtra as above): though the object of the fifth recollection has shifted to 施事, internal wording still preserves "delighting in practicing the dhamma of letting-go" (樂行捨法) — evidence that the translators still possessed the distinction between cāga and dāna, and retained it as a sub-register even when the primary term was replaced.

Assembled: the Chinese Saṃyuktāgama fascicle 33 systematically relocates the cāga track toward the dāna track. The ruling on the four limbs takes only sīla (sūtra 935); the fourth position in the five-virtue foundation is replaced with 施 (sūtras 930, 932); the object of the cāga-recollection is replaced with "the matter of giving" (sūtra 931); structural preservation survives only at the classification level of lay accomplishments (sūtra 927), with internal operational language dāna-inflected.

The softening is not a translation accident. The Chinese translation lexicon distinguishes clearly between 布施 (dāna) and 捨 (cāga); the translators were fully equipped to render either. The softening is selective, and selective softening indicates selective pressure. In the mid-fifth-century Chinese Buddhist context in which these translations crystallized, cāga as an inner mental-factor dimension was already being drawn, under the semantic gravity of merit / field-of-merit / offering discourses, toward the behavioral surface of 布施. The Chinese tradition retained structural acknowledgment of cāga (lay five-accomplishments, the sixfold recollection) but, at the most consequential position — the definitive ruling on the fruit of stream-entry — took the sīla path as its canonical choice.

Viewed from a Western-reader framing, this finding sharpens rather than weakens the paper's argument: the contemporary English-speaking unease with the Chinese Buddhist idiom of "giving = merit" is not a Western prejudice. It is an implicit recognition of the cāga → 施 slide that had already been partially completed at the Chinese translation stage. To raise this unease from emotional response to scholarly judgment requires a double retrieval: first back from contemporary English "generosity" to the Chinese 布施 / 捨, then from Chinese back to the Pāli cāga. This paper performs the second retrieval.

2.2 Register B: Commentary

• Buddhaghosa, Visuddhimagga VII.5, Cāgānussati-niddesa¹⁴: the Theravāda commentarial treatment of cāga. Three points bear on the present argument. First, in commenting on the phrase "I dwell at home" (agāraṁ ajjhāvasāmi) in the cāgānussati formula, Buddhaghosa explicitly identifies Mahānāma as a sotāpanna: "In the suttas, Mahānāma the Sakyan is a stream-enterer; he asked about the dwelling-condition; hence the dwelling-condition was taught to him — 'I dwell at home' meaning 'I dwell having mastered it' (abhibhavitvā vasāmī ti attho)." This identification, matched with Kāḷigodhā's own stream-entry declaration at SN 55.39, gives us two independent Pāli witnesses within the commentarial and canonical layers that the cāgānussati formula is taught to, and inwardly verified by, stream-enterers. Second, in describing the effects of cāgānussati cultivation, Buddhaghosa lists five features: the practitioner "becomes more inclined toward letting-go" (bhiyyosomattāya cāgādhimutto hoti), "holds an intention of non-greed" (alobhajjhāsayo), "acts in conformity with loving-kindness" (mettāya anulomakārī), "becomes fearless" (visārado), "abounds in rapture and gladness" (pītipāmojjabahulo). These five describe the operating profile of a mind trained in cāga, not a moral portrait of "a good person." Third, Buddhaghosa judges that cāgānussati, like the other anussati subjects, reaches access concentration (upacāra-jhāna) but does not enter absorption (appanā) — a structural feature of the anussati system as a whole (already established in NIAN P01), not a limitation peculiar to cāgānussati.

• Yogācārabhūmi-śāstra, Śrāvakabhūmi / Bodhisattvabhūmi¹⁵: relevant sections will be unfolded in P11 (From Dāna to Dāna-Pāramitā) and P14 (The Bodhisattvabhūmi Chapter on Giving). The present paper registers them only as a forward reference, not as an active source.

Note on commentarial structure: following the methodological discipline of Part I (P01 §2.2), this paper operates as a two-voice exposition — Buddhaghosa as primary, Yogācāra sources as supplementary — rather than a three-family dialogue. The reason is documentary: the early Pāli material has only one systematically developed commentarial tradition. Full three-family dialogue (Nāgārjuna / Asaṅga–Vasubandhu / Buddhaghosa) becomes available in Part IV, with the Mahāyāna treatises on giving.

III. Core Argument

3.1 The structural meaning of the triple rotation

P01 used the sīla ↔ cāga swap of SN 55.31/55.32 as evidence that cāga holds equal weight with sīla in the four-limb structure, functioning as proof that cāga is neither a subset of sīla nor a mere behavioral act within the three-term semantic field. That reading holds. But reading SN 55.33 into the set changes the character of the structure entirely.

SN 55.31 (sīla), SN 55.32 (cāga), SN 55.33 (paññā) are three consecutive suttas. The introductory formula is identical in all three ("Mendicants, there are these four overflows of merit..."), the first three limbs are identical (unshakable confidence in Buddha, Dhamma, Saṅgha), only the fourth position varies. The compilers' intent is not "to let the reader see that sīla and cāga can be exchanged" — that captures only the pairwise relationship between two of the three texts, ignoring the structure formed by all three. Nor is it "to let the reader see that wisdom can replace ethical conduct" — this is just the binary reading inverted. The compilers' actual intent is to design "the fourth position of the four limbs" as a structurally rotatable slot, filled in three consecutive suttas with three distinct qualities, so that the reader sees the flexibility of the position itself.

The design carries a doctrinal judgment: the inner marks of a stream-enterer are not single-faceted. From the angle of sīla, the mark is "accomplishment in noble ethical conduct" — behavioral integrity, unbroken, unblemished, conducing to concentration. From the angle of cāga, the mark is "muttacāga" — the structural loosening of "mine" in the mind. From the angle of paññā, the mark is "udayatthagāminiyā paññā" — penetrative insight into arising and passing away. The three mark the same inner state from three different sides: the behavioral side, the mental-factor side, the insight side. Which side the teaching foregrounds depends on the listener's capacity, but all three are co-present in the realized state — a person whose muttacāga has actually loosened cannot still be leaking in their sīla, nor still be closed off from penetrative insight.

In other words: the fourth position is not unselected. The three compilers are not saying "define a stream-enterer however you want." They are saying the position is structured to have three equivalent openings, each of which reveals the same inner state from its own angle.

This resolves an otherwise awkward question: if cāga is truly equal to sīla in weight, why does the Pāli canon not simply fix the four limbs as "Buddha, Dhamma, Saṅgha, cāga" — why the rotation? The answer: cāga is one of three legitimate fillers of this position, not its unique occupant. The rotation is not a contest among candidates; it is three facets rotating in sequence.

3.2 The five-virtue foundation — why these three

Why does sīla, cāga, and paññā rotate in the fourth position, and not energy (vīriya), patience (khanti), mindfulness (sati), or faith (saddhā)? These are all wholesome qualities; why can they not also rotate?

The answer requires moving back from the four limbs to the five-virtue foundation (§II Group 3). Three features of the compression reveal the logic:

Faith is already absorbed. The first three limbs are unshakable confidence (aveccappasāda) in Buddha, Dhamma, Saṅgha. Aveccappasāda is the highest form of saddhā — not belief in a proposition but verified confidence in the three reference points of the path. Once saddhā has been distributed across the first three positions of the four-limb structure, it has no further place to appear in the fourth.

Learning is conductive, not foreground. Suta (learning, what has been heard) makes cultivation possible — one cannot practice what one has never received — but it is not itself a directly observable inner mark. In the "overflows of merit" framing that stresses fruition-marks, suta has already been absorbed into the first three limbs (unshakable confidence in the Three Jewels presupposes having learned the teaching). It does not need to reappear in the fourth.

Sīla, cāga, paññā as the three visible marks. What remains are three qualities, each of which corresponds to a directly observable and self-verifiable facet of the noble disciple's inner constitution: sīla is behavioral self-regulation, cāga is the mental-factor release of mine-making, paññā is insight-level penetration. Each of the three is an independent, observable phenomenon in itself; in any genuine stream-enterer, achievement in any one of them entails the other two (because the five virtues form a structural whole, not a mechanical sum). Which of the three is used to diagnose the realization depends on which face is most prominent to the observer or the practitioner themselves — but the three paths all converge on the same inner state.

This confirms cāga's standing as a faculty of path: it is not an occasional candidate that happens to fit the slot. It is a stable member of the five-virtue foundation, surfacing in the four-limb teaching as one of three legitimate rotational marks.

3.3 What "kind" of faculty — activation conditions at SN 55.40

Recognizing cāga as a faculty of path requires further specifying what kind of faculty it is. Is it a static possession (like a sword — once held, the work is done), or a dynamic configuration (like an athlete's conditioning — without sustained training, it decays)?

SN 55.40 gives the answer unambiguously: dynamic configuration.

The sutta is precise: a noble disciple endowed with the four limbs who becomes satisfied with those limbs (santuṭṭho), who ceases daily striving in solitude and nighttime meditation, is a heedless-dweller (pamādavihārī). The heedless-dweller does not generate gladness (pāmojja); without gladness, no rapture (pīti); without rapture, no tranquility (passaddhi); without tranquility, no bliss (sukha); without bliss, the mind does not concentrate (cittaṁ na samādhiyati); without concentration, dhammas do not become manifest (dhammā na pātubhavanti). A noble disciple not satisfied — continuing exertion — is a heedful-dweller (appamādavihārī), and the entire sequence unfolds.

The structural meaning of this passage runs deeper than its surface: possession of the four limbs is not the terminus of the path, it is the starting point. Having the limbs makes one a being "standing in the stream"; to reach the far shore requires the entire inner causal sequence — from gladness through the manifestation of dhammas — to run continuously. And that sequence activates only under heedfulness, not under possession alone.

Returned to cāga: possession of cāga establishes the structural position of the faculty — the mind has undergone a structural release around "mine," and macchera no longer has its unchallenged grip. But structural position is not full deployment. The unfolding of cāga's complete function (with its downstream chain of gladness, rapture, tranquility, bliss, concentration, manifestation of dhammas, all oriented toward liberation) requires sustained non-satisfaction, sustained forward motion. This is precisely why cāgānussati is so prominent in early texts — the function of recollection is to re-activate the faculty, converting structural position into kinetic deployment.

This dynamic reading also clarifies why the Pāli describes cāga through five marker-words rather than one. The five markers are not synonyms; they are five dimensions of a single dynamic configuration: already-loosened (state), hand-washed-clean (readiness), delighting in relinquishment (disposition), responsive to requests (receptivity), delighting in giving and sharing (initiative). A fully activated cāga deploys all five dimensions simultaneously; intermittent flashes of any one of them are not yet full activation.

SN 55.40 does not address cāga specifically — its formulation uses the sīla variant — but the structural principle possession ≠ activation applies uniformly across all three rotational fillers. Cāga is no more or less reliant on heedfulness than sīla or paññā; they are parallel in this respect.

3.4 Kāḷigodhā's self-declaration — cāga's empirical demonstration

The structural claim is one thing; the fact that an actual person has taken cāga as the primary track, self-verified stream-entry, and received the Buddha's approval is another. SN 55.39 provides the second.

Kāḷigodhā's response to the Buddha is carefully structured. First, she affirms that the teaching describes her actual condition: "these qualities are present in me, and I am seen to possess them" (saṁvijjante dhammā mayi, ahañca tesu dhammesu sandissāmi). This is a declaration that the teaching's content is already the case with her, not a reception of it as aspiration.

Second, she enumerates the first three limbs — unshakable confidence in Buddha, Dhamma, Saṅgha — reciting the full itipi so formula (the Pāli text's triple "...pe..." marks her full recitation).

Third — and most significantly — she addresses the fourth limb not in the Buddha's five-marker formulation but in her own words: "In our household, whatever is a fit thing to be given, all of it, without discrimination, is shared with the virtuous and those of good qualities."

The substitution deserves notice. The Buddha's formula describes cāga at the mental-factor level — the inner state of mind. Kāḷigodhā's self-description operates at the behavioral level — the concrete distribution of household goods. She has not altered the teaching; she has translated it through her own lived experience, rendering the mental-factor description into a behavioral reality she can directly point to. This is the kind of translation only a real practitioner can perform — not a technical exercise but an act of inward recognition.

Fourth, she adds a qualifier absent from the Buddha's formulation: "with the virtuous and those of good qualities" (sīlavantehi kalyāṇadhammehī). The Buddha's five markers include "delighting in giving and sharing" (dānasaṁvibhāgarato) but specify no recipient. Kāḷigodhā's addition is practical supplement to the teaching — as someone who has actually realized cāga, she is telling us how cāga operates in concrete situations: not as undiscriminating, automatic giving to all comers, but as the loosening of "mine" coupled with clear-eyed recognition of the recipient's quality. This line of thought is directly continuous with Nāgārjuna's later position in the Mahāprajñāpāramitā-śāstra, where purity of giving-mind and discernment regarding the field of merit operate in parallel, neither absorbing the other. Real cāga is not the blind inversion of macchera; it is clear discernment after mine-making has loosened.

The Buddha's reply is short: "It is a gain for you, Godhā, a great gain for you, Godhā. You have declared the fruit of stream-entry yourself." Two acclamations followed by one certification. No correction, no supplement, no demand for omitted qualifications. This concise endorsement is itself a substantive doctrinal judgment: the self-declaration of stream-entry by a laywoman using the cāga formula is not only accepted; its self-declarative format is itself judged complete.

Within the Puññābhisandavagga, SN 55.39 is structurally unique. The other nine suttas are either the Buddha teaching to an assembly (SN 55.31–38) or teaching a specific person without a self-verification response (SN 55.22, 55.40). Only in SN 55.39 does a laywoman self-declare the fruit using the cāga formula and receive the Buddha's immediate approval. This is the most direct, most personalized textual witness to cāga as an empirically demonstrable faculty of path.

3.5 Why specifically cāga — countermeasure to the root construction

A more fundamental question remains. Among the many wholesome mental factors, why is cāga — not patience (khanti), not energy (vīriya), not loving-kindness (mettā), not mindfulness (sati) — selected into the stream-entry candidate sequence? All are excellent qualities; why can they not rotate in the fourth position?

The answer lies in what the root construction of saṃsāra is.

Early Buddhism locates the psychological root of saṃsāra in mine-making (mamattā, also keyed to asmimāna, the conceit "I am") — the automatic operation by which the mind applies the category "mine" to any given object. Buddhaghosa's precise definition of macchera in the Visuddhimagga (cited in P01) reads: "the characteristic of being unable to bear that one's own possessions become shared with others." This is not an emotional problem, not a magnitude problem — it is the structural refusal of the mind to allow the category 'mine' to extend into 'mine-and-also-theirs. And this structural operation is the psychological substrate on which saṃsāra continues to run: each moment's construction and defense of "mine" accumulates into the ownership of karma, which drives the next moment's continuation.

Other wholesome factors operate downstream:

• Khanti (patience) handles the emotional response to suffering — but the source of suffering (the touching of "mine") is not within patience's reach.
• Vīriya (energy) handles motivation — but what motivation drives toward depends on the mine-configuration behind it.
• Mettā (loving-kindness) handles interpersonal orientation — but loving-kindness still passes through the "I / other" category-split.
• Sati (mindfulness) handles present-moment awareness — but the object of mindfulness can still be "my body," "my feelings," "my mind."

Each of these is part of the path, but each operates above the mine-making structure. Only cāga works at the root — directly addressing the structural operation itself, the question of whether "mine" can be allowed to become "not only mine." The literal sense of muttacāga — "with the binding released, letting-go" — points precisely at this: what is released is not emotional tension but the structural tension of the "mine" category.

This is why the fourth limb position can hold cāga. A being who has actually realized muttacāga has undergone one structurally irreversible loosening of the root construction of saṃsāra. That irreversible loosening is, in its psychological dimension, the definition of sotāpatti (stream-entry, entering the current of liberation). The four-limb formula uses cāga as one of its rotational marks because, within the five-virtue foundation, cāga is the one virtue that directly targets the root construction.

Sīla works the behavioral face of the same inner state; paññā works the insight face. All three matter, all three rotate. But when the teaching needs to point at where saṃsāra loosens at its root, cāga is the most penetrating name. This is the structural reason SN 55.32 chooses cāga, SN 55.39 chooses cāga for the laywoman, and AN 6.25 places cāgānussati at the fifth position of the six recollections — immediately after sīlānussati and before devatānussati, tracking the progression from behavior to mental-factor to fruition.

3.6 AN 8.36 — the structural fork between transactional dāna and path-faculty cāga

Theoretically, the argument that cāga is a faculty of path is now complete. What remains is a critical piece of evidence for divergence: does the early canon itself distinguish between "transactional giving for merit" and "path-faculty letting-go"? The answer is yes, and the distinction is drawn sharply.

AN 8.36 Puññakiriyavatthusutta¹⁶ lists three grounds of meritorious action: dānamaya (constituted by giving), sīlamaya (constituted by ethical conduct), bhāvanāmaya (constituted by meditative cultivation). The sutta then unfolds a layered scheme:

• a person with only small development of dānamaya and sīlamaya, without bhāvanāmaya: rebirth in "the unfortunate section of the human world"
• with moderate development, still without bhāvanāmaya: rebirth in "the fortunate section of the human world"
• with extensive development of dānamaya and sīlamaya, without bhāvanāmaya: rebirth among the Four Great Kings
• then, layer by layer: the Tāvatiṃsa, Yāma, Tusita, Nimmānarati, Paranimmitavasavatti (the highest deva-realm)

The structure is transparent: extensive giving combined with extensive ethical conduct, if unaccompanied by meditative cultivation, reaches at most the highest deva-realm — the ceiling of the transactional path. Bhāvanāmaya puññakiriyavatthu — the cultivation that carries one across the stream — lies outside this track.

This sutta supplies a structural fork:

• Dāna as transaction: accumulation of meritorious deeds → deva-rebirth (ceiling: Paranimmitavasavatti). This is a closed loop — one puts in meritorious action, one gets back higher deva-rebirth; one consumes that deva-rebirth, one returns to the human realm or lower. The wheel of saṃsāra continues turning, just along a preferred track.
• Cāga as faculty of path: loosening of mine-making → fruit of stream-entry → the current of liberation. This is an opening — an exit cut out of the closed saṃsāric loop.

The same physical action (handing over property) can be operated as a merit-accumulation transaction (with deva-rebirth as ceiling) or as a mine-loosening faculty of path (with stream-entry as outcome). The difference lies neither in the action, nor in the amount, nor in the recipient. The difference lies in the inner structure — whether macchera still manages the transaction (with merit-tracking as its overlay), or whether cāga-adhimutta has established itself as the default disposition.

This distinction is not deduced by the present paper — AN 8.36 draws it itself. Bhāvanāmaya as the third class of meritorious action is not listed as "more of the same merit"; it is placed in a structurally different category. It does not raise the ceiling of deva-rebirth; it opens a different route entirely.

Contemporary Western readers' wariness toward "merit discourse" is therefore not misplaced. What they intuitively resist is precisely the closed-loop ambience of the "extensive giving + extensive ethical conduct → Paranimmitavasavatti" path — no matter how fervent the practice, that path cannot reach liberation. The cāga path argued in this paper is exactly the route early Buddhism itself marked out at AN 8.36 as other than the merit-transaction path: a route that opens from the structural loosening of mine-making and proceeds directly to the current of the noble ones, not via the splendor of the highest deva-realms.

3.7 Synthesis of the six layers

Assembling the six sub-arguments: cāga is a faculty of path (sotāpattiyaṅga in the strict sense), because

1. The structural fact of rotation (3.1): the fourth slot of the four-limb formula is a rotatable position taking sīla, cāga, paññā in sequence; cāga is one of three legitimate fillers.
2. Foundational standing in the five virtues (3.2): cāga is a stable member of the five-virtue substrate, not an accidental candidate.
3. Dynamic activation (3.3): SN 55.40 shows cāga is a configuration requiring sustained heedfulness for full deployment, not a static possession.
4. Empirical demonstrability (3.4): SN 55.39's Kāḷigodhā self-declares the fruit of stream-entry on the cāga track and receives the Buddha's approval — the track is walkable in practice.
5. Direct countermeasure to the root construction (3.5): cāga alone, among the wholesome factors, works at the root of mine-making, which is why it is selected into the stream-entry candidate sequence.
6. Self-divergence of the canon (3.6): AN 8.36 itself separates bhāvanāmaya from dānamaya + sīlamaya, distinguishing the transactional path from the path-faculty path in the canon's own terms.

These six layers converge on a single conclusion: early Buddhism did not accidentally, inattentively place cāga in the fourth limb position. The placement was structurally considered — cāga is located there because, in this doctrinal context, it precisely names the root construction that stream-entry loosens. Reading cāga as "giving with meritorious intent" displaces a faculty that properly belongs inside the bone of the path into the position of ritual trappings of the path. Restoring cāga to its original position makes the whole teaching on giving legible as a main line of cultivation — from P01's three-term analysis, through this paper's treatment of stream-entry, into P03's unfolding of the cāgānussati practice.

IV. Interdisciplinary Dialogue: Cāga and Costly Signaling Theory

Evolutionary biology has a mature theory called costly signaling theory, proposed by the Israeli biologist Amotz Zahavi in 1975 and later extended to religion by anthropologists such as Richard Sosis, Joseph Bulbulia, and Scott Atran. Its core claim: individuals (including humans) perform costly donations, sacrifices, ascetic practices, and self-mortification because these costs function as honest signals of commitment and resource-endowment to other members of the group, yielding adaptive benefits in mate selection, coalition stability, and cooperative trust. More costly religious behavior is more effective at signaling — not despite the cost, but because of it.

The theory offers a highly successful account of the socio-biological mechanism behind religious giving. It explains why large donors in religious communities consistently acquire higher social status, why public generosity outperforms private generosity in building community trust, and why some religious traditions develop increasingly stringent norms of giving (the stricter the norm, the more credible the signal). At the descriptive level, the theory has serious explanatory power for many observable contemporary religious practices.

A dangerous analogical temptation now arises: to read cāga as a meditatively optimized costly signaling system. "Buddhism's cāga is just a refined, contemplation-polished form of costly signaling." The analogy reads smoothly: muttacāga (loosening) = signal emission; Kāḷigodhā's "sharing with the virtuous" = community-trust construction; heavenly rebirth in the cāgānussati teaching = anticipated return. Smoothly enough that an unexamined observer might think some real problem has been resolved.

The analogy is directionally mis-set. Three layers of analysis:

Where they resemble each other. Both frameworks describe a "pay a cost, receive a return" structure. Costly signaling theory: pay material resources, acquire adaptive benefit (mates, coalitions, trust). Transactional dāna: pay material resources, acquire karmic benefit (better next life, deva-rebirth). At the pay → return level, the two are structurally parallel. This parallel is precisely why the cāga track argued here is not either of them: cāga is, in AN 8.36's own schema, structurally separated from the transactional "giving + conduct" route to higher rebirths.

Where they fundamentally diverge. Costly signaling theory presupposes that the value of the cost arises from the return it brings — the more paid, the more securely the adaptive benefit accrues; the causal loop is the theory's very ontological spine. Cāga as a faculty of path runs on the reverse break of that loop: the definition of muttacāga is "the binding released," which is precisely the loosening of the expectation mechanism itself. A giver who is still computing returns — no matter how sophisticated the contemplative technique — is operating on the costly-signaling path, not the cāga path. The fundamental difference is not rhetorical, not quantitative, not about the recipient — it is about whether the causal-expectation structure has been loosened.

The reductive cost. Reading cāga as an evolved costly signaling system collapses the entire cultivation architecture into adaptation theory. Kāḷigodhā's "unreserved sharing" becomes an extreme signal; the Buddha's approval becomes a community-trust construction ritual; the doctrinal status of the fruit of stream-entry — exit from the saṃsāric current — is replaced with "building high-trust relationships in a present-day community." The two aims are not merely different; they point in opposite directions: costly signaling builds deeper integration into relational networks; cāga builds release from the root construction of relational networks (the "mine" category that underlies all network positions). Explaining one with the other is like explaining "why one swims" with "the design principles of a ship" — the failure is not insufficient explanation but category misassignment.

⚠️ Unidirectional analogy notice. Costly signaling theory can help a Western reader new to the concept of cāga quickly identify the pseudo-cāga phenomena around them — the religiously wrapped, substantively signaling-driven forms of devout giving that are endemic in contemporary religious life. That identification is useful. But the reverse does not hold: one cannot use cāga teaching to solve costly signaling's socio-biological problems (e.g., "how to make a given community's religious signals more credible"). That belongs to the domain of cultural evolution, and cāga teaching is not designed for it.

The analogy travels in one direction (from costly signaling toward cāga, for recognition), not the reverse (using cāga to optimize signal efficiency). The first is recognition work on the path; the second is a social-engineering technical problem. The two domains cannot substitute for each other. It is worth noting that the structure of this divergence is formally identical to the divergence AN 8.36 drew between dāna + sīla and bhāvanā — it is simply the same watershed re-performed in the vocabulary of modern science.

V. Middle Way Corrections

❌ Misreading 1: cāga = altruism

Contemporary positive psychology and prosocial behavior research extensively use "altruism" as a measurable personality dimension or behavioral category. Such research has its own value — but downgrading cāga into this category gets the direction wrong.

The word "altruism" (from Latin alter, "other") presupposes, both etymologically and operationally, that the I / other distinction still holds: there is a self, and it learns to direct resources toward "the other." Cāga in the Pāli sense operates precisely at the structural basis on which the I / other distinction is built — the mine-making construction. A being who has realized muttacāga has not "become more altruistic"; that being's category "mine" has begun to loosen at the root, and the downstream behavior merely looks altruistic from outside. Reading the loosening of the root construction as a higher altruism score reads structural transformation as quantitative increase.

When Kāḷigodhā describes her household sharing, she does not say "my self has become more altruistic." She says "whatever fit thing to be given, all of it, without discrimination ..." — and this "whatever / all / without discrimination" construction is not the register of increased altruism; it is the register of the "mine" category beginning to deconstruct.

❌ Misreading 2: cāga = Stoic detachment from externals

The Greco-Roman Stoic tradition (oikeiōsis, apatheia) teaches practitioners to build a detached attitude toward external things — wealth, reputation, bodily health should not move the mind's tranquility. Some contemporary English-language Buddhist writing, for the convenience of Western readers, uses Stoic tradition as a bridge for cāga — "letting-go" and "detachment" feel close, point to similar kinds of inner stability.

Bridges are useful, but cannot become equations. Stoic detachment's structure: a complete "self" builds a non-attached relationship toward "external things". One end of the relationship remains "self," the other end "external things"; only the rope between them has been loosened. The goal is for the self to remain unshaken by external fluctuations.

Cāga's structure: the category "mine" itself begins to loosen. Not "I am detached from external things" — rather, the constitutive operation by which "external things become mine" is itself loosened. A Stoic sage's "self" still stands intact, he has simply learned to be unperturbed about "his wealth"; a stream-enterer in whom muttacāga has arisen is not unperturbed about "his wealth" — the category "his" has taken its first irreversible fracture.

The difference lies in what is being processed: Stoic practice processes the relationship between "self" and "externals"; cāga processes the underlying operation that constitutes the categories "self," "mine," and "externals" in the first place. Downstream behavior may resemble (both will appear calm about gain and loss), but the upstream root construction is in entirely different positions.

❌ Misreading 3: reading the triple rotation as "stream-entry without sīla" or "stream-entry without paññā"

The triple rotation in SN 55.31–33 could tempt a convenience reading: "Since the fourth position can be sīla, cāga, or paññā, one of the three is sufficient" — this reading does not hold.

The triple rotation is a teaching-presentation choice, not an empirical-constitution choice. The five-virtue foundation (faith, ethical conduct, learning, letting-go, wisdom) is a structural integrity — a genuine stream-enterer possesses all five; missing any one, the realization has not occurred. The purpose of compressing five virtues into four limbs is teaching economy: the three Jewels confidences (absorbing faith) + one rotational mark. That the rotational mark rotates means "any one of these three can serve as the visible diagnostic"; it does not mean "this being possesses only one of the three."

A comparison: a physician diagnosing illness can examine the eyes, read the pulse, or check the tongue — three valid diagnostic channels. No physician concludes that "a mistaken pulse alone suffices for illness while correct eyes and tongue make no difference." Eyes, pulse, and tongue are three faces of a single condition; any one's abnormality reflects that the condition has arisen, but in practice they co-manifest. The triple rotation in the fourth limb is analogous: sīla, cāga, and paññā are three faces of stream-entry, any one can serve as the diagnostic mark, but the three co-manifest — they do not substitute for one another.

⚠️ Caution 1: the costly-signaling analogy runs one way only

§IV unpacks this in full. The analogy travels from costly signaling toward cāga (useful for recognizing pseudo-cāga); the reverse does not travel (one cannot apply cāga teaching to the socio-biological problems of costly signaling). Cultivation domain and cultural-evolution domain cannot substitute for each other.

⚠️ Caution 2: the Chinese systematic softening is not "the Chinese tradition got it wrong"

§2.1 Group 4 records the Saṃyuktāgama fascicle 33's systematic softening of the cāga track. This record is a philological observation, not a critique of the Chinese tradition. The Chinese tradition has its own doctrinal emphases (foregrounding noble ethical conduct and verified confidence, in step with the social integration needs of Chinese Buddhism). The Chinese choice to take the sīla track as canonical ruling on the four limbs, and to let "giving" (施) cover most of the cāga territory, coheres with the tradition's overall temperament. This paper does not blame the softening; it retrieves the softened dimension from the Pāli side so that the two traditions can supplement each other. Reading only the Chinese gives a stunted understanding of the cāga track; reading only the Pāli misses the rich Chinese vocabulary history of "letting-go" as a term in the dharma. Dual-track reading is what makes the full picture available.

⚠️ Caution 3: the heedfulness principle applies to all four limbs, not to cāga exclusively

SN 55.40's "possession ≠ activation" principle is a structural rule that applies to all four limbs. The sutta itself uses the sīla variant — the Buddha teaches a noble disciple already accomplished in ethical conduct that "even with ethical conduct, without heedfulness no gladness arises..." The rule applies uniformly to sīla, cāga, paññā. Do not read this as "cāga is a uniquely heedfulness-dependent track." All stream-entry marks are marks of standing on the stream; reaching the far shore, from any of them, requires heedfulness.

---

VI. Conclusion

6.1 The core thesis restated

Cāga is a faculty of path — a cultivation function of independent structural standing in the architecture of liberation, of equal rank with sīla and paññā. Six layers of evidence converge: the triple rotation of the four-limb fourth slot (SN 55.31–33), stable membership in the five-virtue foundation (SN 55.21, AN 6.25, AN 11.11), dynamic activation as configuration (SN 55.40), empirical demonstrability through Kāḷigodhā's self-declaration and the Buddha's approval (SN 55.39), direct countermeasure to the root construction of mine-making, and the canon's own structural fork at AN 8.36 between transactional dāna and path-faculty cultivation.

In contrast, any downgrading reading — cāga as merit-accumulator, as altruism-trait, as costly signaling, as Stoic detachment — loses the same thing at the same point: it drops cāga's standing as a direct countermeasure to the root construction of mine. Contemporary English-speaking unease around merit-talk is not prejudice; it is an accurate recognition of the cāga → 施 slide that had already been partially completed at the Chinese translation stage. This paper performs the retrieval back across that slide, restoring cāga to its original position among the four limbs of stream-entry.

6.2 Practical orientation

If cāga is a path-faculty configuration requiring sustained heedfulness to remain activated, then "how much should I give" is not the central question. The central question is: did this act of giving touch the "mine" structure?

If it touched — even one dollar, even half a glass of water — muttacāga was operating, cāga was being activated. If it did not touch — a large sum, an impressive charitable naming — the mind stayed put, the "mine" structure did not move at all, no activation occurred. This diagnostic is inward, not outward; structural, not quantitative.

A concrete operational hint: attend to the 0.3-second inward contraction at the moment of giving — the "inward flinch" P01 already identified. That flinch is macchera's response-signal at the boundary of "mine" being touched. After this giving, did the flinch loosen a little? Or did it contract and automatically re-tighten? This can be observed inwardly. Cāga's operation happens in that millisecond-scale window. Ignoring the window and only reading the ledger keeps one permanently outside the gate of the cāga teaching.

A second hint: heedfulness. Even when one instance of muttacāga has operated — the flinch loosened — do not imagine one is thereafter "a generous person." SN 55.40's warning applies to every cultivator: possession ≠ activation. Every act of giving must re-initiate the mechanism; every day is a re-activation. Cāga is not an accumulated medal; it is a training maintained daily.

6.3 Open questions and hook to the next chapter

If cāga is one of three rotational marks, what is the relationship among the three? At the practice level, does working on one of the three automatically bring forth the other two, or do the three require separate cultivation? More specifically: as a sotāpanna progresses to sakadāgāmī (once-returner), anāgāmī (non-returner), and arahant, how does the cāga faculty transform? Does it remain unchanged, or does each fruit-stage deepen it qualitatively?

These questions fall outside "cāga as a limb of stream-entry" and are not addressed here. They are the natural extensions.

The more immediate extension is the next chapter (P03, The Six Recollections and Cāgānussati). This paper has treated cāga as a limb (a structural inner state); the next chapter treats cāga as a meditation object (a recollectable, cultivable referent). The limb is substance; the recollection is function. With substance established, how does function unfold? Why does the early canon place cāgānussati at the fifth position of the six recollections — between sīlānussati and devatānussati — and what does that position itself say? These are the questions P03 will take up. The present paper closes here.

• Pointing at the Moon Octalogy, S2 series (Heart Sūtra): §3.5's claim that "mine-making is the root construction of saṃsāra" runs methodologically parallel to the Heart Sūtra's "seeing through the five aggregates' emptiness, liberating from all suffering" — cāga works the "mine" face of the five-aggregate self-grasping, while prajñā works the "I" face. A full cross-reference at the mental-factor level will appear in P15.

9. Saṃyuktāgama (《雜阿含經》), fascicle 33, sūtra 935, translated by Guṇabhadra (Liu Song), Taishō Tripiṭaka vol. 2, no. 0099. This sūtra is the Chinese canon's definitive ruling on the four limbs of stream-entry, with the Buddha adjudicating that "the four qualities constituting stream-entry are: unshakable faith in the Buddha, in the Dhamma, in the Saṅgha, and accomplishment in noble ethical conduct." ↩

10. Saṃyuktāgama (《雜阿含經》), fascicle 33, sūtra 930. Parallel to SN 55.21. The five-virtue list in Chinese reads "perfumed by ethical conduct, giving, learning, wisdom," replacing the Pāli cāga with 施. ↩

11. Saṃyuktāgama (《雜阿含經》), fascicle 33, sūtra 931. Parallel to AN 11.11. The fifth recollection's object is replaced from the Pāli cāga with "the matter of giving" (施事), though the internal phrase "delighting in the dhamma of letting-go" (樂行捨法) is preserved as sub-register. ↩ ↩²

12. Saṃyuktāgama (《雜阿含經》), fascicle 33, sūtra 932. The five-virtue foundation reads "taking right faith as foremost, rooted in the accomplishment of ethical conduct, of learning, of giving, and of wisdom." ↩

13. Saṃyuktāgama (《雜阿含經》), fascicle 33, sūtra 927. This sūtra preserves "accomplishment in letting-go" (捨具足) at the classification level of lay five-accomplishments, but the five internal marker-words have been rendered as "liberated giving, diligent giving, constant giving, delight in relinquishing wealth, equal giving" — a four-fold structure (yācayogo has no visible counterpart). ↩

14. Buddhaghosa, Visuddhimagga VII.5 Cāgānussati-niddesa. PTS edition pp. 223–224. This paper, following P01's paraphrase-only discipline, does not directly quote the GRETIL edition of the Visuddhimagga in order to avoid the share-alike conflict between its CC-BY-SA license and this volume's CC-BY-NC-SA license. Buddhaghosa's identification of Mahānāma as a sotāpanna, the five-feature description of cāgānussati cultivation effects, and the judgment that cāga as meditation subject reaches only access concentration are all paraphrased from the text. ↩
