Paṭṭhāna — Conditional Relations

Paṭṭhāna — An Exposition of the Book of Conditional Relations

Background

Paṭṭhāna, literally meaning "Origin" or "Arising," is venerated as the "Great Treatise" (Mahā-pakaraṇa) in the Theravāda tradition. It is the seventh and most voluminous book of the Abhidhamma Piṭaka, taught by the Buddha at the Tāvatiṃsa heaven during a three-month rains retreat for the purpose of liberating his mother, Queen Mahā-māyā.

Tradition records that after expounding the first six books of the Abhidhamma, the Buddha revealed Paṭṭhāna as the pinnacle of insight — a thorough analysis of the mechanism of dependent origination (paṭicca-samuppāda) governing all phenomena throughout the three realms of existence. This treatise embodies the Tathāgata's omniscience (sabbañña-ñāṇa) with respect to every possible causal relationship between dhammas — from material phenomena to mental phenomena, from the wholesome to the unwholesome, from the conditioned to the unconditioned.

Principal Contents

Paṭṭhāna unfolds a system of twenty-four conditions (paccaya) that fully account for every causal relationship in the universe of dhammas. These twenty-four conditions are: root condition (hetu-paccaya), object condition (ārammaṇa-paccaya), predominance condition (adhipati-paccaya), proximity condition (anantara-paccaya), contiguity condition (samanantara-paccaya), co-nascence condition (sahajāta-paccaya), mutuality condition (sampayutta-paccaya), support condition (nissaya-paccaya), decisive-support condition (upanissaya-paccaya), pre-nascence condition (purejāta-paccaya), post-nascence condition (pacchājāta-paccaya), repetition condition (āsevana-paccaya), karma condition (kamma-paccaya), result condition (vipāka-paccaya), nutriment condition (āhāra-paccaya),

faculty condition (indriya-paccaya), jhāna condition (jhāna-paccaya), path condition (magga-paccaya), association condition (sampayutta-paccaya), dissociation condition (vippayutta-paccaya), presence condition (atthi-paccaya), absence condition (natthi-paccaya), disappearance condition (vigata-paccaya), and non-disappearance condition (avigata-paccaya).

Each condition is analyzed through four modes: the positive (anuloma), the negative (paccanīya), the positive-negative (anuloma-paccanīya), and the neither-positive-nor-negative (n'eva anuloma na paccanīya). The treatise proceeds to combine these conditions with the twenty-four categories of dhammas found in the Dhammasaṅgaṇī, generating millions of possible relational patterns. This scope explains why Paṭṭhāna is regarded as the most extensive book in the entire Tipiṭaka, with its full content potentially running to tens of thousands of pages.

The profound significance of Paṭṭhāna lies in its demonstration that no dhamma arises by chance or through the agency of a creator, but that all things arise in dependence upon conditions. This firmly establishes the teaching of non-self (anattā), for there is no unchanging entity standing behind phenomena — there is only the continuous stream of dependent arising in relation.

Practical Significance

The study of Paṭṭhāna helps the practitioner develop insight wisdom (vipassanā-paññā) into the conditioned nature of all phenomena. When one clearly sees that every mental state and every physical phenomenon arises in dependence upon conditions, one recognizes that there is nothing to cling to, and that there is no "self" or "mine" to be found in any dhamma whatsoever.
