Toh 4217Untitled

Exposition of Toh 4217 — Tengyur Treatise Collection

Context

This scripture belongs to the Treatise Collection (Tengyur) of the Northern Tibetan Mahayana tradition, one of the largest collections of Buddhist scriptures and treatises translated and compiled in Tibet from the ninth through the thirteenth centuries. The Tengyur contains more than 3,600 treatises (Śāstra) explaining the scriptures taught by the Buddha and composed by Indian bodhisattvas and eminent monastics.

The scriptural treatises in the Tengyur are classified by subject: treatises on prajna wisdom, the Middle Way, meditative concentration of mind, ethics, and the governance of the practicing community. They are steps by which Mahayana practitioners gain a deeper understanding of the Buddha’s teachings, particularly Mahayana scriptures such as the Avatamsaka Sutra, the Lotus Sutra, and sutras concerning skillful means (Upāya).

Although the original title of Toh 4217 has not been clearly identified in the descriptive information, based on its placement in the Tengyur, this scripture is very likely a treatise on a core Mahayana subject related to the theory of mind (Citta) or bodhisattva conduct.

Main Content

Treatises in the Tengyur commonly explore three principal areas: Prajñāpāramitā (the Perfection of Wisdom), Madhyamaka (the Middle Way), and Yogācāra (Mind-Only). Although the specific content of Toh 4217 has not been fully translated into Vietnamese, it may focus on one of these fields.

If this scripture belongs to Yogācāra, it will explain how consciousness (ālaya-vijñāna) is the foundation of all phenomena. Mind is the basis of every experience, and by transforming this consciousness through practice, the practitioner attains Buddhahood.

If this scripture belongs to Madhyamaka, it will explore Śūnyatā (emptiness), namely the absence of an independently existing essence in all dharmas. This is the core of Prajñāpāramitā, which teaches that everything that can be cognized lacks a fixed intrinsic nature (svabhāva).
