Exposition of Scripture Toh 4398 — Northern Mahāyāna Tradition

Context

Scripture Toh 4398 belongs to the Tengyur—the collection of śāstras in the traditional Tibetan Buddhist canon. It is one of the most important canonical treasuries of Mahāyāna Buddhism and was compiled from translations made from Sanskrit into Tibetan during the period of the Later Dissemination of Buddhism, beginning in the ninth century.

The Tengyur differs from the Kangyur (the collection of scriptures) in that it contains treatises explaining and developing the teachings of the Buddha’s Dharma, rather than teachings spoken directly by the Buddha. These works were composed by eminent masters, particularly those of the Yogācāra and Madhyamaka schools, to clarify the profound meaning of the Dharma.

The absence of a specific title for this scripture reflects the manner in which many treatises circulated within the Tibetan tradition: they were known through their content, scholastic context, and location within the Tengyur rather than by a single title.

Main Content

Although the detailed content of Scripture Toh 4398 has not been fully translated in this context, its position within the Tengyur suggests that it is a treatise belonging to a Mahāyāna philosophical system, possibly concerning such essential subjects as: (1) the nature of mind (cittamātra), (2) the doctrine of emptiness (śūnyatā), or (3) the bodhisattva path of practice.

Treatises in the Tengyur are often structured around explanations of difficult points in the scriptures, answers to practical questions about cultivation, or the development of systems of logic for defending Buddhist teachings against philosophical challenges. They follow the methodology of reasoning and valid cognition (pramāṇa)—the study of the criteria for valid knowledge.

Practical Significance

Although its specific title is unknown, Scripture Toh 4398 represents the intellectual heritage of Tibetan Mahāyāna Buddhism, in which the Dharma is not only revered with faith but also studied profoundly through reasoning and analysis.
