Exposition of Toh 4423 — Abhidharma Treatise Collection (Tengyur) of the Northern Tibetan Tradition

Context

The text Toh 4423 is a work belonging to the Abhidharma Treatise Collection (Abhidharmakośa-bhāṣya) within the Tengyur of the Northern Tibetan tradition. This collection comprises commentaries and treatises explaining the Buddha's doctrinal systems, composed after the Buddha's time by noble beings, bodhisattvas, and accomplished sages. It is an important doctrinal foundation of the Mahayana, particularly in the Northern Tibetan tradition, where the three divisions—Sūtra, Vinaya, and Abhidharma—are regarded as indispensable to practice and study.

The Tengyur is the largest collection of treatises and commentaries in Tibetan and comprises more than two hundred volumes. The profound purpose of these works is to clarify the deep meaning of the Sūtra collection, dispel misunderstandings, and provide a systematic path of practice for bodhisattvas pursuing awakening.

Main Content

Although its specific title has not yet been fully translated, Toh 4423 belongs to a collection of treatises devoted to Mahayana teachings. Works in this collection commonly address essential subjects such as the nature of consciousness (cittamātra—mind-only), selflessness (anātmā), buddha-nature (Buddha-dhātu), and the bodhisattva path.

In the Northern Tibetan tradition, these treatises are taught alongside the sūtras so that scholars may deeply comprehend subtle concepts. The Northern Tibetan tradition particularly emphasizes the role of logic and philosophy (pramāṇa—reliable cognition) in clarifying the Dharma. Thus, these treatises not only explain Buddhist principles but also demonstrate them through rigorous reasoning.

The Tengyur's treatise collection includes sections on Abhidharma, bodhisattva practice, definitions of philosophical concepts, and methods for cultivating the entire Mahayana path. Together, these sections constitute a comprehensive doctrinal system.
