An Explanation of Toh 4115 — The Tengyur Treatise Collection

Background

Toh 4115 belongs to the Treatise Collection (Tengyur) of the Northern Tibetan Mahayana tradition, one of the richest collections of Buddhist literature in the world. The Tengyur was compiled during periods of revival, particularly from the eighth through the twelfth centuries, when eminent translators such as Bodhisattva Jinamitra, Dánshúg, and Tibetan masters painstakingly translated more than 4,500 treatises from Sanskrit into Tibetan.

The Treatise Collection is a compilation of commentaries (bhāṣya) and subcommentaries (ṭīkā) by great masters such as Vasubandhu, Dignāga, Dharmakīrti, and others, intended to clarify the profound meaning of the sacred scriptures. Although the specific title of Toh 4115 has not been fully transliterated in the descriptive information, it is certainly a scholastic treatise whose task is to explain and defend the Mahayana Dharma. Such treatises are not independent compositions, but form part of a continuous interpretive lineage in which every author builds upon the foundations laid by predecessors, thereby creating a profound and interconnected system of Buddhist thought.

Main Content

Treatises in the Tengyur generally focus on three principal fields: Buddhist philosophy, including the doctrine of non-self and analysis of the nature of mind; the ethics of practice, including Vinaya; and philosophical systems such as Madhyamaka, Yogācāra, and others. According to the Northern Tibetan tradition, these treatises emphasize the importance of precise logic (tserig, or pramāṇa) in establishing the Mahayana Dharma.

A central theme in the Treatise Collection is the explanation of how Mahayana practitioners develop the bodhisattva mind (bodhicitta) and practice the six pāramitās: generosity, ethical discipline, patience, diligence, meditation, and wisdom. These treatises provide rigorous arguments explaining why such practices lead to the unfolding of bodhisattva wisdom and how practitioners may avoid errors during the course of practice.
