A set of cognitive and communicative concepts from the Sanskrit intellectual traditions, for designers, researchers, and people building and leading with AI.
Cognitive and communicative concepts from the Sanskrit intellectual traditions, for designers, researchers, and people building and leading with AI.
A reference of operational concepts drawn from the Indian Knowledge Systems. Each card names a move you can make in your work - a question you can ask, a discrimination you can draw - that the available English vocabulary does not give you a clean way to name. Each card has an English title leading, with the Sanskrit term as a subtitle. Each card closes with a Diagnostic Question, an IKS Roots section for the Sanskrit apparatus, and a short further-reading note.
Each card has an English title leading, with the Sanskrit term as a subtitle. The card carries a tradition ID (N for Nyaya, Y for Yoga, M for Mimamsa, V for Vedanta, G for Vyakarana grammar, A for Alankara-shastra poetics, O for other), an applicability tag — Users of tech products, Builders, Stewards who set direction — a gist line, then a body in plain English. Each card closes with a Diagnostic Question, an IKS Roots section for the Sanskrit apparatus, and a short further-reading note. A 'Where the closest English-language analog falls short' section appears where the comparison sharpens the card. Some cards skip it because the concept has no obvious English near-neighbour to set against.
Users - anyone working with tech products day-to-day. Writers using LLMs, knowledge workers querying assistants, anyone receiving AI output as part of their work.
Builders - anyone making tech products. Developers, designers, prompt engineers, ML practitioners, UX writers, anyone touching how the product behaves.
Stewards - anyone setting direction or judging the work. Product managers, design leads, research leads, founders, evaluators, brand owners, executives.
Pramana Cards
A1
Meaning by Resonance
dhvani
A piece of communication carries meaning at several layers — what it denotes, what it secondarily refers to, and what it makes resonate. The third is where the actual work tends to happen.
Builders
Stewards
A2
Designed Emotional Response
rasa
Aesthetic emotion is a designed effect, generated in the qualified reader by the structural conditions the artist constructs. It is a third thing — distinct from the artist's feeling and from the reader's everyday emotion — that arises only under the artwork's structural conditions. The frame is what every form of experience design is doing, named at the level the English vocabulary does not name it.
Builders
Stewards
A3
Oblique Expression as Aesthetic Principle
vakrokti
Kuntaka's principle that aesthetic value lives in the deviation from the straightforward way of saying. The crooked saying — the slight twist that lifts an utterance out of mere information into art — is what *vakrokti* names. The frame is what good copy, memorable interfaces, and effective communication design all share at the level of construction.
Builders
Stewards
A4
Receiver as Design Constraint
sahṛdaya
The artwork's effect arises only when it meets a receiver equipped to receive it. The Indian poetics tradition makes this receiver a design constraint: the work has to be built for someone, and that someone has to have been cultivated. The frame is what user research, audience targeting, and the discipline of writing for an actual reader all are when treated structurally.

G1
Semantic Roles in Action
kāraka
Every action involves a small number of distinct roles — agent, object, instrument, recipient, source, locus. Many design and communication failures are failures to keep these straight.
Users
Builders
G2
Gestalt Unity of Utterance
sphoṭa
Meaning is grasped as a whole. The parts arrive in succession but never assemble themselves into the whole — the whole is given otherwise. Bhartrhari names the unitary meaning-bearing event the *sphoṭa* and analyses how the parts of an utterance manifest it without being it. The frame matters wherever a system or a reader is taking the sequence of tokens for the meaning they jointly carry.
Builders
Stewards
G3
Secondary or Indirect Meaning
lakṣaṇā
When the primary meaning of a word fails the context, the word generates a secondary meaning through a determinate semantic relation. The Indian tradition analyses the relation, the conditions for activation, and the kinds of secondary meaning. The frame is what every act of interpretation does when literal reading does not fit, and what no English vocabulary names cleanly.
Users

G4
Grasping of Meaning
śaktigraha
The classical Indian analysis of how the relation between a word and its meaning is learned. Eight named means: grammar, lexicon, dictionary, the word of a trusted authority, the speech of elders, the context of usage, association with a known word, and the sentential context itself. The frame is what model training, language acquisition, and onboarding to specialised vocabulary all are at the level of process.

M1
Postulation from Inexplicability
arthāpatti
Some observations cannot stand on their own — they require an unstated fact to be coherent. The unstated fact is then known by the necessity of making the observation make sense.
Users
Builders
Stewards
M2
Utterance Types
vidhi / niṣedha
An utterance that tells someone to do something is doing different work from an utterance that describes or one that prohibits. Mimamsa worked out the typology and the operational consequences. The frame names what interface affordances, policy rules, prompt instructions, and content moderation guidelines all are at the level of speech act.

N1
Orientation to Valid Cognition
pramāṇa-vichāra
Not all knowledge has the same shape. The Indian epistemological tradition maps six distinct routes by which a knowledge claim can be valid, each with its own structure and its own failure modes. Knowing which route is in play sharpens what you are doing.
Users

N2
Necessary Co-occurrence
vyāpti
When you claim that X and Y go together, are they bound by necessity or running in parallel by coincidence? This card gives you the test that separates the two.
Users

N3
Positive and Negative Instance Sets
sapakṣa / vipakṣa
Valid inference requires not just instances where the relation holds, but instances where it would have failed if the relation were false. The two sets do different work, and using only one is a failure mode.
Builders
Stewards
N4
Locus of Inference
pakṣatā
Before you ask whether something is true, you have to locate where the question actually lives — the substrate the inquiry is about. Many inquiries fail because the locus has been mis-set, often without anyone noticing.
Users
Builders
Stewards
N5
Counterbalanced Reasons
satpratipakṣa
Sometimes two equally strong reasons support contrary conclusions, and the right move is to suspend judgment; adjudication is unavailable by the structure of the case. The card gives you the name for that situation and lets you stop pretending it does not exist.
Builders
Stewards
N6
Test of Commitments
tarka
Assume the opposite of what you want to establish, follow the implications, and watch what breaks. The Nyaya method of testing inferential commitments by hypothetical entailment, different from open-ended thought experiment.
Users
Builders

N7
Non-perception as Knowledge
anupalabdhi
How do you know that something is not there? Not by inference and not by ordinary perception, but by a distinct cognitive route — the non-perception of what would have been perceived if present.
Users
Builders
Stewards
N8
Testimony as a Means of Knowing
śabda
A great deal of what anyone knows comes from being told. The Indian schools worked out a structured account of when verbal communication is a valid route to knowledge and when it fails — operational at a level Western epistemology only recently caught up to.

O1
Modes of Mental Tone
triguṇa — sattva, rajas, tamas
The classical three-fold analysis of qualitative texture — the tonal mode in which a state, an act, or an arrangement is happening. Not three values but three structural modes that mix in varying proportions and dominate at different moments. The frame names what every act of qualitative judgement is doing when it asks "what kind of state is this."
Users

O2
Willful Transgression against Wisdom
prajñāparādha
The act of doing what one knows to be wrong for oneself. Ayurveda names this the structural root cause of self-generated disease and suffering — the failure to act on what wisdom already sees. The frame is what every act of motivated self-undermining is doing, treated as a distinct category — where Western vocabularies reach for moral failing or weakness of will.

O3
Four Aims for Human Flourishing
puruṣārtha
Four irreducible aims the Indian tradition holds together as constitutive of a full human life — *dharma* (right ordering and role), *artha* (resources and means), *kāma* (desire and pleasure), and *mokṣa* (liberation). The frame names what value frameworks usually flatten by reducing to one axis. Each aim has its own legitimacy and its own pathology when pursued without the others.

V1
Superimposition as Structure of Error
adhyāsa
Error has a structure: the properties of one thing are laid on another, and the resulting cognition is taken as straightforwardly given. Sankara analyses this not as a motivated mistake but as the basic mechanism by which the mind constructs misapprehension. The frame matters wherever a system or a person is taking the qualities of one thing to be the qualities of another and acting on the composite.

V2
Real, Unreal, and Indeterminable
sat / asat / anirvachanīya
Advaita Vedanta uses a three-valued ontology where some objects are neither plain real nor plain unreal but something the apparatus refuses to settle. The frame surfaces a class of objects — AI outputs, fictional characters, dream-contents, branded perceptions — that everyday ontology mishandles by forcing into the real-or-unreal binary.
Builders
Stewards
V3
Positive and Negative Concomitance
anvaya-vyatireka
A disciplined paired test: hold the conditions, vary the candidate property, see what tracks. The Indian formulation makes the positive and negative arms a single methodological unit — you have not established concomitance until you have done both. The frame is what causal inference, ablation studies, and A/B testing all are at the level of method.
Builders
Stewards
V4
Apparent and Real Transformation
vivarta / pariṇāma
Two distinct theories of how transformation happens. *Pariṇāma* — the substrate actually changes into the new form (milk to yoghurt). *Vivarta* — the substrate appears as the new form without itself changing (rope appears as snake). The frame distinguishes surface change from substrate change wherever the difference matters — in product updates, in model versioning, in personal transformation.

Y1
Five Modes of Mental Activity
pañca-vṛtti
The mind has five distinct modes of activity, each with its own structure. Naming them separately lets you ask which mode is in play before treating any of them as the generic "thinking."
Users

Y2
Cognition without Object
vikalpa
When the mind generates a coherent representation that has nothing behind it, what kind of cognitive event is that — and how is it distinct from being wrong about a real thing?
Users

Y3
Mistaken Cognition with Real Referent
viparyaya
Mistaken cognition with a real referent — a thing is there, the mind takes it for something else. Different from *vikalpa* (no referent at all) and from valid cognition; the operational fix differs in each case.
Users

Y4
Mistaking Constructed for Natural
avidyā
The root mis-cognition is positive — an active mis-taking that treats the contingent as necessary, the constructed as natural, the impermanent as permanent. Having the name for the move lets you catch it.

Y5
Fusion of Awareness with Instrument
asmitā
The cognitive event in which the witness collapses into the instrument of cognition — the seer takes itself to be the seen. Specific to Yoga's analysis of how identity gets misplaced onto tools, faculties, and roles.
Users
Builders
Stewards
Y6
Dispositional Traces
saṁskāra
Every experience leaves a latent imprint that predisposes future cognition and action without determining it. The frame names what statistical priors and habit-loops only describe — a structural layer of the mind that accumulates and conditions, and that present action both arises from and creates.
Builders
Stewards
Y7
Seer and Seen
dṛk / dṛśya
A structural separation: the witnessing capacity and everything that can be witnessed are different in kind. The frame keeps the question of where observation lives in a system distinct from the question of what is being observed — and matters wherever an architecture must decide which parts watch and which parts act.
