Of the three divisions of the Buddhist canon, the Abhidharma is the one almost nobody reads. The discourses are narrative and quotable; the Vinaya is full of incident; the Abhidharma consists largely of lists, definitions, and the systematic permutation of categories, sometimes for thousands of pages.

It is also the layer of the tradition that determined how everything later was thought about. This article covers what it is, how it came to exist, and what it claims.

The name #

Abhi-dharma is usually rendered “higher Dharma” or “concerning the Dharma.” Both readings have support. The prefix abhi- can mean “higher, superior” — the traditional reading, asserting the Abhidharma’s superiority to the discourses — or “concerning, with reference to,” giving a more modest sense of the material as meta-level analysis.

The philological consensus favours the second as the original meaning, with the honorific sense developing later as the schools elevated the status of their systematic literature. The Pali form is Abhidhamma; the Sanskrit is Abhidharma.

What is in it #

The Theravada Abhidhamma Pitaka has seven books:

  1. Dhammasangani (“Enumeration of Dhammas”) — the foundational catalogue, classifying all phenomena under a set of triplets and couplets, beginning with wholesome, unwholesome, and indeterminate.
  2. Vibhanga (“Analysis”) — eighteen chapters analysing major categories: aggregates, sense-bases, elements, truths, faculties, dependent origination, and so on.
  3. Dhatukatha (“Discussion of Elements”) — relating the categories to one another systematically.
  4. Puggalapannatti (“Designation of Persons”) — a classification of types of person, and the book closest in style to the discourses.
  5. Kathavatthu (“Points of Controversy”) — over two hundred debates against positions held by other Buddhist schools, in a formal question-and-answer structure.
  6. Yamaka (“Pairs”) — questions posed in matched forward and reverse form, to eliminate ambiguity in the definitions.
  7. Patthana (“Conditional Relations”) — the largest and most demanding, working through twenty-four types of condition across all the categories. In the Burmese tradition it is called the Mahapakarana, the Great Book, and reciting it is a meritorious act in itself.

The Sarvastivada collection is also seven books, differently organised, and was in its turn summarised and criticised in Vasubandhu’s Abhidharmakosha, the most widely studied Abhidharma text outside the Theravada world.

Where it came from #

The tradition and the historians disagree here, and the disagreement is instructive.

The Theravada account holds that the Buddha taught the Abhidhamma in the Heaven of the Thirty-Three to his mother, reborn there as a deity, during the seventh rains retreat after his awakening — descending daily to summarise the day’s teaching to Sariputta, who elaborated it. The Kathavatthu is acknowledged to have been composed by Moggaliputta Tissa at the Third Council, but is held to have been outlined by the Buddha in anticipation.

The Sarvastivada account attributes its seven books openly to named disciples rather than to the Buddha.

The historical account traces the Abhidharma to a practice visible in the discourses themselves: the matika or matrka, mnemonic lists of doctrinal terms used as an aid to recitation and teaching. Several discourses — the Sangiti Sutta and Dasuttara Sutta in the Digha Nikaya, both attributed to Sariputta — are essentially organised lists of doctrinal items grouped by number. Expand the lists, define each item, cross-classify, and you have an Abhidharma.

The linguistic evidence supports a later date than the discourses: the Abhidharma uses a more technical and standardised vocabulary, and the Kathavatthu refutes positions that could only have arisen after the schools divided. The scholarly dating is roughly the third century BCE to the second century CE for the core, with commentary continuing for centuries after.

That the different schools’ Abhidharmas differ substantially, while their discourse collections agree closely, is itself strong evidence that the Abhidharma was composed after they separated.

The dharma theory #

The central claim is a distinction between two levels of description.

Conventional truth (sammuti-sacca) describes the world in terms of persons, objects, and wholes: a chariot, a house, a woman named Mallika.

Ultimate truth (paramattha-sacca) describes it in terms of dhammas — the irreducible constituents that actually exist, each with its own defining characteristic.

A conventional entity is a designation applied to an arrangement. Take the arrangement apart and you find no chariot over and above the parts. Take the parts apart and you find, eventually, dhammas — which cannot be taken apart further.

The Theravada list has 82: 28 kinds of materiality, 52 mental factors, consciousness (counted as one dhamma with many varieties), and nibbana. The Sarvastivada has 75, the Yogacara 100. Of these, only nibbana — and, in the Sarvastivada, space and two kinds of cessation — is unconditioned. Everything else arises and ceases in dependence on conditions.

Two properties do the work. Dhammas have sabhava, their own defining characteristic, which is what distinguishes one from another. And they are momentary: they arise, exist briefly, and cease, with apparent continuity being a rapid succession.

The 24 conditions #

The Patthana’s account of conditionality is the Theravada Abhidhamma’s most distinctive contribution, and it is more sophisticated than the simple causal language of the discourses.

It enumerates twenty-four ways in which one thing can condition another: root condition, object condition, predominance, proximity, contiguity, co-nascence, mutuality, support, decisive support, prenascence, postnascence, repetition, karma, result, nutriment, faculty, jhana, path, association, dissociation, presence, absence, disappearance, and non-disappearance.

The point of the apparatus is that “cause” is too blunt. An object conditions the consciousness that takes it, but not in the way a seed conditions a sprout; a prior moment conditions the next by immediately preceding it, which is different again. The Patthana then works through which dhammas can relate to which under which conditions, exhaustively — which is why it is enormous.

What it is for #

Three purposes, in the tradition’s own account.

Precision. The discourses use words as ordinary speakers do. The Abhidharma fixes them. Once “feeling” means one specific factor with a defined characteristic, statements about feeling can be tested for consistency across the whole corpus.

Defence. The Kathavatthu exists to refute other Buddhists. A school with a systematic position can argue; a school with an anthology of conversations cannot.

Practice. This is the purpose the tradition emphasises most. Insight meditation requires seeing experience as it actually is — as a flow of conditioned, impermanent, impersonal events. The Abhidharma provides the categories. The Visuddhimagga’s account of the stages of insight is Abhidharma applied, and the modern Burmese vipassana methods inherit the framework directly.

The objections #

Reification. The main internal criticism: having analysed the self away into dhammas, the Abhidharma treats dhammas as having intrinsic existence. Nagarjuna argues that the same analysis applied consistently dissolves them too. Whether sabhava in Abhidharma usage means “substantial intrinsic existence” or merely “defining characteristic” is genuinely disputed; Noa Ronkin has argued that the Theravada usage is the weaker one and that Nagarjuna’s target is more specifically the Sarvastivada.

Scholasticism. That the system elaborates beyond any practical use. The Chan tradition built an identity on this objection.

Authenticity. Theravada, Sarvastivada, and the Mahayana schools each reject the others’ Abhidharma as not the Buddha’s word. The Sautrantikas — “those who follow the sutras” — rejected the Abhidharma’s canonical status in principle.

Common questions #

Do I need to study the Abhidharma? Not to practise. Many accomplished meditators have never opened it, and in Burma, where it is most emphasised, it is a specialist study. It becomes useful when you want precision about what the practice instructions are pointing at.

Where should I start? Not with the canonical books. Anuruddha’s Abhidhammattha Sangaha, an eleventh- or twelfth-century summary, is the traditional entry point, and Bhikkhu Bodhi’s Comprehensive Manual of Abhidhamma presents it with a full modern guide.

Is the Abhidharma the same in all traditions? No. Theravada and Sarvastivada produced separate collections with different contents and different conclusions. Tibetan monastic education studies the Sarvastivada system through Vasubandhu; East Asian traditions largely set the Abhidharma aside after the Tang.

Is it a psychology? It is a systematic analysis of mental events, and the comparison is useful. It is not a psychology in aim — its classifications are organised around what conduces to liberation — and it contains a great deal that no psychology would recognise, including rebirth-linking consciousness and the materiality of beings in other realms.
