Exposition of the Scripture Toh 2591 — Tengyur Treatise Collection

Context

Toh 2591 is a work belonging to the Treatise Collection (Abhidharmapitaka) of the Northern Transmission, compiled and preserved in the Tibetan Tengyur. The Mahāyāna tradition of the Northern Transmission, also called the Tibetan Buddha Dharma tradition or Vajrayāna, developed upon the foundation of Mahāyāna Buddha Dharma and integrated profound teachings on mind, jñāna (perfect wisdom), and wondrous practices.

The Treatise Collection is the third part of the Three Baskets (Tripiṭaka), containing commentaries, explanations, and doctrinal analyses of the Buddha Dharma by deeply realized Buddhist masters. The works in the Tengyur are precious commentaries by great Indian teachers, translated into Tibetan during the official translation period from the seventh to the thirteenth centuries.

Main Content

Although the official title of Toh 2591 has not yet been fully translated, according to its position and classification in the Tengyur, this work belongs to the line of commentaries on Abhidharma, the doctrine concerning the elements that constitute experience (dharma) and the way they interact in the process of practice.

In the Tibetan tradition, Abhidharma is not merely dry philosophical theory, but a practical tool for understanding the nature of mind and the impermanent (anicca) and non-self (anattā) factors. This work may focus on one of the central themes: analysis of mental factors (caitasika), the mental elements that accompany the primary mind; or the classification of conceptual and nonconceptual dharmas; or an explanation of the attainment of each stage on the path of practice.

Tibetan Abhidharma commentaries are built upon classical works such as Vasubandhu’s Abhidharmakośa, but are expanded and deepened through teachings on Mind-Only (Yogācāra) and Madhyamaka principles, forming a comprehensive system of understanding mind and reality.
