Toh 4066Untitled

An Explanation of Toh 4066 from the Treatise Collection

The Northern Tibetan Mahayana Tradition

Background

Toh 4066 is a treatise found within the Tengyur—the repository of Dharma treatises in Tibetan Buddhism. The Tengyur contains commentaries and treatises by earlier bodhisattvas and Buddhist noble beings, embodying the Northern Tibetan Mahayana tradition that developed especially from Indian Buddhism through sages such as Nāgārjuna, Asaṅga, and Vasubandhu.

This work was compiled and translated between the eighth and twelfth centuries, when Tibetan Buddhist Dharma studies reached their height. The treatises in the Tengyur are not original sutras but teachings by highly accomplished bodhisattvas intended to explain, interpret, and illuminate the profound meaning of the Mahayana sutras. They serve the needs of religious teachers and practitioners following the bodhisattva path.

Although its English and Vietnamese titles have not been fully recorded in the catalog, Toh 4066—as part of the Mahayana corpus—naturally contains profound teachings on the nature of the Buddha Dharma.

Main Content

Treatises in the Tengyur commonly focus upon three principal areas: Buddhist philosophy, contemplative practice, and theories of buddha-nature. According to the Northern Tibetan tradition, Toh 4066 is understood to be a commentary or treatise explaining one of the fundamental aspects of the Buddha Dharma.

Within the context of the Tengyur, works such as this commonly explain concepts concerning emptiness (śūnyatā)—the central doctrine of the Mahayana—or the nature of mind and awakening. They may discuss the Four Noble Truths, the nature of buddha-nature, or the stages of practice on the bodhisattva path.

According to the Northern Tibetan tradition, especially the Gelug school and other schools, treatises such as this are regarded as guiding lights that help prevent errors in understanding and cultivate prajnaparamita—the capacity to understand profoundly the true nature of phenomena.
