Toh 1265Untitled

Exposition of Toh 1265 — Tengyur, the Treatise Collection (Northern Tibetan Mahayana Tradition)

Context

Toh 1265 belongs to the Treatise Collection (Śāstra) of the Tengyur — the collection of treatises explaining the Buddhadharma composed by Indian great masters. In the Northern Tibetan Mahayana tradition, especially through the Tibetan schools such as Gelug, Kagyu, and Nyingma, the Treatise Collection is regarded as an authoritative source that helps scholars deeply understand the intended meaning of the scriptures. Although the title of the work has not yet been fully translated, its position in the Tengyur system shows that this is a systematic exegetical work intended to clarify an important aspect of the Mahayana Buddhadharma.

The period of compiling the Tengyur extended from the eighth to the thirteenth centuries, with major revisions under Tibetan emperors. The authors of these treatises were often masters of profound practice, capable of transforming the teachings into rigorous systems of reasoning suited to the intellectual context of India and, later, Tibet.

Main Contents

Although this work’s descriptive information has not disclosed its detailed title, based on its position in the Treatise Collection, this work is likely a commentary on one of the central themes of the Mahayana, such as the theory of the bodhisattva path, the nature of buddha-nature, or skillful means of teaching (upāya).

In the Northern Tibetan tradition, such treatises often follow a structure: first presenting the main position (siddhānta), then giving persuasive reasoning step by step (anumāna), and then refuting opposing positions. This method reflects the influence of the Indian Buddhist school of analytical logic, such as that of Dignāga and Dharmakīrti.

The distinctive point of these treatises is that they do not merely present ideas, but also teach how each practitioner can recognize and realize those truths directly. Thus, they are a bridge between scripture and the practice of cultivation.
