school_scope: "Nyāya-Vaiśeṣika primary — the distinction between nirvikalpaka (indeterminate, pre-classificatory) and savikalpaka (determinate, conceptually structured) pratyakṣa is developed most systematically in the Nyāya tradition (Nyāyabhāṣya, Nyāyamañjarī, Nyāyakusumāñjali); Mīmāṃsā engagement — Prabhākara's school disputes whether nirvikalpaka constitutes a separate pramāṇa; Kumārila's school accepts it in a modified form; Buddhist (Dignāga-Dharmakīrti) engagement — the Dignāga-Dharmakīrti tradition draws a cognate but architecturally different distinction between pure sensory pratyakṣa (kalpanāpoḍha — free from conceptual construction, grasping the svalakṣaṇa/unique particular) and conceptual cognition (kalpanā); in the Buddhist account, what Nyāya calls 'savikalpaka pratyakṣa' would not be pratyakṣa at all (it would be inference-like); Advaita Vedānta application — Advaita appropriates the nirvikalpaka/savikalpaka distinction to describe the epistemic quality of brahma-jñāna: aparokṣa-anubhūti is described as having a 'nirvikalpa' quality (non-conceptual, not structured by subject-object distinction); this is a specific Advaita application and should not be confused with the Nyāya epistemological account"

not:
  - term: "sense-datum"
    why: "Western analytic philosophy's sense-datum theory (Russell, Moore, Price) posits atomic sensory qualia as the basic building blocks of perception; nirvikalpaka is not a sense-datum; nirvikalpaka is a complete perceptual cognition of an individual object (the pot, the cow) in its pure particularity, without conceptual overlay; the sense-datum theory concerns what is ultimately perceived; the nirvikalpaka/savikalpaka distinction concerns stages of the same perceptual event"
    instead: "Keep Indeterminate and Determinate Perception untranslated; do not substitute the English term."
  - term: "unconscious"
    why: "nirvikalpaka is not unconscious; Nyāya considers it a real cognition (jñāna) — it has epistemic content; what makes it epistemically recessive is not that it is unconscious but that (a) it is ineffable — it cannot be expressed in language because language requires names and kinds (vikalpas), and (b) it cannot be separately recalled — when we remember perceiving a cow, we remember the savikalpaka \"this is a cow,\" not the preceding nirvikalpaka contact; but this epistemic recessiveness is not the same as unconsciousness"
  - term: "raw feel (qualia)"
    why: "philosophical qualia (the phenomenal character of experience — what it is like to see red, feel pain) is a different concept from nirvikalpaka; nirvikalpaka in Nyāya is a cognitive event with a specific object (a pot, a cow, a color), not a qualitative feel in the phenomenological sense; conflating nirvikalpaka with qualia imports a mind-body dualism that is foreign to the Nyāya framework"
  - term: "concept-free (as full description)"
    why: "while nirvikalpaka is literally \"without vikalpas\" (without conceptual differentiation — name, kind, quality, relation), calling it simply \"concept-free\" obscures that it still has an object (the svalakṣaṇa, the unique particular) and a cognitive content; it is not blank or empty; it is cognitively full but structurally undifferentiated; \"pre-conceptual\" or \"pre-classificatory\" is more accurate"
  - term: "nirvikalpa-samādhi (Pātañjala Yoga)"
    why: "Pātañjala Yoga uses nirvikalpa to describe a meditative state beyond all content; this is different from Nyāya's nirvikalpaka pratyakṣa (a stage of ordinary perception) and from Advaita's nirvikalpa brahma-jñāna; the three uses of \"nirvikalpa\" in these three traditions are distinct; see yoga-darśana bundle for the Pātañjala usage"

# Nirvikalpaka / Savikalpaka — निर्विकल्पक / सविकल्पक

**Not:** sense-datum, unconscious, raw feel (qualia), concept-free (as full description), nirvikalpa-samādhi (Pātañjala Yoga)

The terms **nirvikalpaka** and **savikalpaka** designate two stages or modes of pratyakṣa (direct perception) that Indian epistemologists — especially in the Nyāya tradition — distinguish within a single perceptual event. Together they address the question: does all perceptual cognition arrive pre-packaged with conceptual structure (names, kinds, qualities, relations), or is there a prior, pre-structural moment of contact from which the conceptual cognition is built?

- **Nirvikalpaka** (from *nir-* [without] + *vi-* [apart, differentiated] + *kalpa* [construction, conceptual form]) — **indeterminate perception**: the initial, pre-classificatory moment of perceptual contact in which the object is cognized in its pure particularity, without the overlay of name, kind, quality, or relational structure.
- **Savikalpaka** (from *sa-* [with] + same root) — **determinate perception**: the fully articulated, conceptually structured perceptual cognition in which the object is cognized as "this is a cow," "this is white," "this has dewlap and horns" — with name, kind, quality, and relations.

## The Epistemological Problem

Every ordinary perceptual cognition arrives with conceptual structure. We do not typically see a shapeless this; we see a cow, a red wall, a tall man. Conceptual structure (names, kinds, qualities) is already present in the cognition as we are aware of it.

But: conceptual structure requires that the mind already possess the relevant universals (jāti — cow-ness, redness) and has applied them to the object. This application — a cognitive act — must have an input: the object as it is prior to conceptual application. What is that input?

Nyāya posits **nirvikalpaka** as the answer: the object is cognized in its pure particularity (svalakṣaṇa — its unique individual character) at a moment prior to conceptual application. The senses are in contact with this particular object; the initial cognition grasps it without any jāti-overlaid. Then, in savikalpaka, the buddhi applies the stored universals (from previous experience + saṃskāra) to form the determinate cognition.

## The Nyāya Account

The Nyāyasūtra 1.1.4 defines pratyakṣa as:

> *indriyārthasannikarṣotpannaṃ jñānam avyapadeśyam avyabhicāri vyavasāyātmakam pratyakṣam*

"Cognition produced from sense-organ-object contact, which is non-verbal (*avyapadeśyam*), non-errant (*avyabhicāri*), and of the nature of determination (*vyavasāyātmaka*), is direct perception."

Commentators use this definition to anchor the distinction:

| Feature | **Nirvikalpaka** | **Savikalpaka** |
|---------|-----------------|-----------------|
| **Cognitive content** | The object's pure particularity (*svalakṣaṇa*) | Object + universal (*jāti*) + quality (*guṇa*) + name (*nāma*) |
| **Linguistic expressibility** | Ineffable (*avyapadeśya*) — cannot be verbalized | Verbal — can be expressed in sentences |
| **Recallability** | Cannot be independently recalled (no word-hook) | Recalled as "I saw a cow" |
| **Epistemic role** | Foundation for savikalpaka; guarantees the object is "this particular" | Full perceptual cognition as experienced |
| **Correspondence to NS 1.1.4** | The *avyapadeśyam* (non-verbal) aspect | The *vyavasāyātmaka* (determinate) aspect |
| **Nyāya validity** | Valid cognition (real pramā) | Valid cognition (real pramā) |

Both stages are **valid pramāṇas** within Nyāya — nirvikalpaka is not mere noise; it is the epistemically real but cognitively recessive contact that grounds the savikalpaka which follows.

## Jayanta's Defense of Nirvikalpaka

Jayanta Bhaṭṭa (9th century, Nyāyamañjarī) offers the strongest Nyāya defense of nirvikalpaka against the Mīmāṃsā challenge. His argument:

1. When we recognize a previously seen particular object — say, a specific pot — we recognize it *as the very same pot*, not merely as *a pot*. This "very same" recognition requires that in the original perception, the object was cognized as this individual particular, not merely as a cow- or pot-instance.
2. If original perception were savikalpaka all the way down — if it only cognized the object as a token of a type — there would be no ground for individual-recognition (re-identification of particulars).
3. Therefore, there must be a stage of perception that grasps the particular as such, prior to type-classification. This is nirvikalpaka.

## The Mīmāṃsā Objection

**Prabhākara's school** disputes nirvikalpaka's status as a separate pramāṇa. The argument:
- We cannot recall nirvikalpaka cognition separately. When we remember a perceptual event, we remember savikalpaka content ("I saw a cow"). There is no memorial residue of the prior nirvikalpaka stage.
- A cognition that leaves no trace and cannot be recalled cannot be confirmed as having occurred.
- Therefore, positing nirvikalpaka as a separate cognitive stage is unnecessary. What Nyāya calls nirvikalpaka may simply be savikalpaka at a very rapid, non-noticed stage of processing.

**The Nyāya response:** The inability to recall nirvikalpaka separately does not prove it did not occur. Recall operates on verbally tagged cognitions (name-kind structure provides the hook for memory). Nirvikalpaka, being ineffable, has no such hook — but this epistemic recessiveness is a consequence of its pre-verbal character, not evidence against its occurrence. The savikalpaka itself requires that the particular was already available, which implies the nirvikalpaka contact.

## The Buddhist Alternative (Dignāga-Dharmakīrti)

The Dignāga-Dharmakīrti school draws a cognate distinction but with a different architectural consequence. Dignāga defines pratyakṣa as *kalpanāpoḍha* — free from conceptual construction (kalpanā). What is kalpanā? The import of names and universals. Pure pratyakṣa grasps only the svalakṣaṇa (unique momentary particular); any cognition that involves names, kinds, or universals is kalpanā — and kalpanā, for Dignāga, falls under **anumāna** (inference-like conceptual cognition), not pratyakṣa.

| | **Nyāya Position** | **Dignāga-Dharmakīrti Position** |
|--|-------------------|----------------------------------|
| Nirvikalpaka | Valid pratyakṣa | True pratyakṣa (their *kalpanāpoḍha*) |
| Savikalpaka | Valid pratyakṣa | Not pratyakṣa — conceptual/inference-like (*kalpanā*) |
| Object of pure pratyakṣa | Svalakṣaṇa (particular) | Svalakṣaṇa (momentary particular) |
| Object of savikalpaka/kalpanā | Sāmānyalakṣaṇa (universal) | Sāmānyalakṣaṇa |

For Nyāya, savikalpaka remains **pratyakṣa** — its conceptual structure is added to a perceptual cognition, not separable from it into a different pramāṇa. For the Buddhist school, the conceptual overlay is precisely what places savikalpaka-type cognition outside the pramāṇa-scope of pratyakṣa.

This is one of the classical debates in Indian epistemology: is a perceptual cognition still pratyakṣa when it is conceptually structured, or does conceptual structure necessarily move cognition into the anumāna domain?

## Advaita Application: Nirvikalpa Quality of Brahma-Jñāna

Advaita Vedānta appropriates the nirvikalpaka/savikalpaka distinction to characterize the epistemic quality of brahma-jñāna (aparokṣa-anubhūti — see aparoksha-anubhuti.md). The key claim: the realization "aham brahmāsmi" (I am Brahman) or the recognition of ātman-Brahman identity in "tat tvam asi" does not have the savikalpaka form "ātman is such-and-such" (predication of a property to a subject). It has the nirvikalpa form — direct, non-predicative, not structured by the subject-object or subject-predicate split.

Why nirvikalpa?
- A savikalpaka cognition maintains the subject-object structure: a subject (pramātṛ) predicates a property of an object (prameya). But Brahman-as-ātman is not an object — it is the cognizer's own nature (svayaṃprakāśa, self-luminous). A savikalpaka "Brahman is X" still treats Brahman as an object of predication.
- Aparokṣa-anubhūti is the recognition that dissolves the very subject-object structure. This dissolution cannot take the form of a savikalpaka cognition, which inherits that structure.
- Hence Vivekacūḍāmaṇi and Pañcadaśī describe brahma-jñāna as *nirvikalpa* — not because it is empty, but because it is without the conceptual differentiation that separates knower from known.

**Advaita's nirvikalpa brahma-jñāna vs. Nyāya's nirvikalpaka pratyakṣa:**

| | Nyāya Nirvikalpaka | Advaita Nirvikalpa Brahma-jñāna |
|--|-------------------|----------------------------------|
| Object | External particular (pot, cow) | ātman = Brahman (the subject's own nature) |
| Subject-object structure | Maintained (perceiver perceives) | Dissolved in the recognition |
| Status | Foundation for savikalpaka pratyakṣa | Does not give rise to a savikalpaka overlay — it is the terminus |
| Occasion | Every perceptual event | The event of aparokṣa-anubhūti |
| Result | Ordinary valid cognition (pramā) | Mokṣa (liberation from saṃsāra) |

The Advaita use is analogical: "nirvikalpa" indicates the absence of the subject-predicate, knower-known structure — but the concept is transposed from the theory of ordinary perception to the theory of liberation-knowledge.

## Cross-References
- [Pratyakṣa](pratyaksha.md) — direct perception; nirvikalpaka and savikalpaka are the two stages of pratyakṣa as analyzed in Nyāya; the whole account belongs within the pratyakṣa pramāṇa
- [Pramāṇa](pramana.md) — the epistemological framework; the question of whether nirvikalpaka is a distinct pramāṇa (Nyāya: yes, as the foundation of savikalpaka pratyakṣa; Buddhist: yes, as the only true pratyakṣa; Prabhākara-Mīmāṃsā: disputed) is a central debate
- [Pramā](prama.md) — veridical cognition; both nirvikalpaka and savikalpaka are pramās in the Nyāya account (valid, object-corresponding, non-sublated cognitions)
- [Anumāna](anumana.md) — inference; the Buddhist debate about whether savikalpaka cognition is really inference-like (kalpanā-laden) rather than genuine pratyakṣa
- [Aparokṣa-anubhūti](aparoksha-anubhuti.md) — the Advaita application of the nirvikalpa concept to describe brahma-jñāna's non-predicative, non-conceptually-structured character
- [Sphoṭa](sphota.md) — the Bhartṛhari philosophy of language has a related distinction: pratibhā (the flash of sentential meaning) is immediate and whole rather than built up compositionally, which parallels the nirvikalpaka character of direct apprehension vs. the compositional character of savikalpaka/explicit articulation

## Audience Metaphor

Consider how you might hear a voice and immediately know 'that's my friend Priya' — the recognition is instantaneous, felt rather than reasoned, and happens before you could articulate why or how you recognized her. That moment of pure recognition, before you say to yourself 'that voice has those specific characteristics that mark it as Priya's' — that's something like nirvikalpaka. When you then articulate 'yes, that's Priya, her voice is distinctive in these ways' — that's something like savikalpaka. The recognition happened before the articulation; the articulation is the cognition made explicit and verbal. Nirvikalpaka is what the savikalpaka rests on.

3. Jayanta Bhaṭṭa, Nyāyamañjarī 1 — extended defense of nirvikalpaka as a genuine pramāṇa against Mīmāṃsā objections; argues that nirvikalpaka must be real because savikalpaka presupposes a prior contact with the object's particularity; one cannot recognize a previously seen particular unless one had first cognized it as a particular (not merely as a cow-instance)
4. Dignāga, Pramāṇasamuccaya 1.3 — kalpanāpoḍham abhyantaṃ pratyakṣam — pratyakṣa is that which is free from conceptual construction (kalpanā); this is the Buddhist version; for Dignāga, kalpanā (conceptual construction) imports names (nāma) and kinds (jāti); pure pratyakṣa grasps the svalakṣaṇa without any such import; what Nyāya calls savikalpaka would not be pratyakṣa for Dignāga but would be kalpanā-tainted
5. Dharmakīrti, Nyāyabindu 1.14 — the svalakṣaṇa (unique particular, momentary) is the proper object of pratyakṣa; the sāmānyalakṣaṇa (universal characteristic) is the object of anumāna; this svalakṣaṇa/sāmānyalakṣaṇa distinction parallels Nyāya's nirvikalpaka/savikalpaka but within a very different ontological framework (Buddhist momentariness vs. Nyāya substance-quality ontology)
6. [Vivekacūḍāmaṇi](/references/vivekachudamani.md) vv. 373–378 (Śaṅkara attr.) — the ātmajñāna (self-knowledge) that constitutes brahma-jñāna is of the nirvikalpa type: it is not of the form 'I am Brahman' in the sense of predicating a property of a subject (which would be savikalpaka) but the direct recognition without subject-predicate structure
