Paṭṭhāna

Summary: The Paṭṭhāna ("Conditional Relations") is the seventh and final book of the Abhidhamma Piṭaka. Known as the Mahāpakaraṇa ("Great Book") due to its immense size and technical complexity, it provides a universal system for understanding how all phenomena (dhammā) are interrelated through a grid of twenty-four conditional relations (paccaya). By applying these relations to the triadic and dyadic matrices, it offers a complete and exhaustive map of the conditional nature of reality (Paṭṭh 1-59; Paṭṭh 60ff; Paṭṭh 29166-29169).

Overview

The Paṭṭhāna is the culmination of the Abhidhamma system. While the earlier books focus on the analytical breakdown of phenomena, the Paṭṭhāna focuses on their synthesis—how they arise and function together. It moves from the static "Enumeration of Phenomena" in the Dhammasaṅgaṇī to a dynamic "System of Relations."

The book's significance lies in its refusal to see any phenomenon as existing in isolation. Every mental and material event is shown to be part of a vast, interdependent network. For example, it explains how a single wholesome thought is conditioned by its root causes, its sensory objects, the dominance of certain mental factors, and the preceding moments of consciousness (Paṭṭh 2-59).

Significance: The Twenty-Four Conditions

The analytical engine of the Paṭṭhāna is the set of twenty-four conditional relations (conditionality paccaya). These relations describe the different ways one dhamma can support the arising or persistence of another. They include:

Structural Conditions — Such as hetupaccaya (root cause) and ārammaṇapaccaya (object-condition).
Temporal Conditions — Such as anantarapaccaya (contiguity) and purejātapaccaya (pre-arising).
Functional Conditions — Such as kammapaccaya (kamma) and āhārapaccaya (nutriment).
Logical Conditions — Such as atthipaccaya (presence) and natthipaccaya (absence).

Through these relations, the Paṭṭhāna demonstrates that causality is not a single linear chain but a multi-dimensional web of conditions.

Structure

The Paṭṭhāna is organized into six major divisions based on how the conditional relations are applied to the Abhidhamma matrices:

Tikapaṭṭhāna — tikapatthana (Conditions applied to the 22 Triads).
Dukapaṭṭhāna — dukapatthana (Conditions applied to the 100 Dyads).
Duka-tikapaṭṭhāna — Conditions applied to combinations of dyads and triads.
Tika-dukapaṭṭhāna — Conditions applied to combinations of triads and dyads.
Tika-tikapaṭṭhāna — Conditions applied to combinations of triads and triads.
Duka-dukapaṭṭhāna — Conditions applied to combinations of dyads and dyads.

Within each division, the text proceeds through four major methods of questioning, named after the corresponding Dhammā-prefixed canonical division headings:

Paccayānuloma (raw: Dhammānuloma) — Positive relations ("Depending on A, B arises").
Paccayapaccanīya (raw: Dhammapaccanīya; Paccanīya for short) — Negative relations ("Depending on A, B does not arise").
Paccayānulomapaccanīya (raw: Dhammānulomapaccanīya; Anulomapaccanīya for short) — Mixed positive-negative relations.
Paccayapaccanīyānuloma (raw: Dhammapaccanīyānuloma; Paccanīyānuloma for short) — Mixed negative-positive relations.

Key themes

conditionality paccaya — The central theme; every page of the book is a demonstration of how dhammas condition one another.
matika matrices — The grid of triads and dyads provides the subject matter for the book's conditional analysis.
kamma action and fruit — Analyzed as a specific type of relational condition (kammapaccaya).
consciousness citta — Shown to be conditioned by sensory objects, roots, and preceding mental states.
Universal Interdependence — The book proves that no dhamma arises without conditions, and no condition operates in total isolation.

How to read

Start with the Paccayuddesa and Paccayaniddesa. Without the opening list and definitions of the twenty-four paccayas, the later Pucchāvāra can look like an endless technical expansion; with them, the reader can see that the later pages are not introducing new theories but repeatedly applying the same defined relations (Paṭṭh 2-59).

Then read the later material by method rather than by trying to absorb every combination. The recurring shifts between anuloma, paccanīya, anulomapaccanīya, paccanīyānuloma, pañhāvāra, and saṅkhyāvāra show that the book is designed to test, invert, summarize, and count the same conditional field across multiple doctrinal grids (Paṭṭh 60ff; Paṭṭh 1379ff; Paṭṭh 29150-29169).

For this wiki, the practical reading rule is simple: the page documents the twenty-four paccayas and the book's structure, not the full combinatorial expansion of every later case. That expansion is central to the canonical book itself, but summarizing it exhaustively would misrepresent the page's text-level scope.

For source handling in this repo, pali-ms.txt is the canonical alignment grid, while pali-bjt.txt preserves the Buddha Jayanthi page-entry segmentation in native form. The page therefore cites canonical Paṭṭh references and the Mahāsaṅgīti grid while leaving the BJT file unresegmented.

Textual notes

The Mahāsaṅgīti Pali (pali-ms.txt) uses patthana... alignment-grid IDs, while the Buddha Jayanthi Pali file preserves native ap-pat:<page>.<entry> page-entry IDs. The two segmentation systems are both retained rather than mechanically forced into one another.
This round has no in-scope English canonical translation for the Paṭṭhāna, and the extracted canonical source files also do not currently provide a Sinhala entry payload for this book. The current page is therefore grounded in the authoritative Pali raw only.
The Mahāsaṅgīti and BJT Pali files differ sharply in granularity (pali-ms.txt segment grid vs. BJT page-entry extracts). They are treated here as parallel native forms, not as a strict entry-by-entry pair.
The page keeps the Paṭṭhāna at text level. It explains the twenty-four paccayas and the book's large structural method instead of pretending to reproduce the whole later combinatorial expansion.
Raw commentary is present separately under raw/commentaries/atthakatha/abhidhamma/patthana/. Commentary Pali and Sinhala native entry counts do not align perfectly there, so commentary remains a separately flagged layer rather than being folded into canonical prose on this page.
