Toh 2158Untitled

Exposition of Toh 2158 — Tengyur, Treatise Canon

Context

Toh 2158 from the Tengyur (Bstan 'gyur) — the Tibetan Treatise Canon — is a treatise belonging to the Northern Mahayana tradition, composed during the golden age of Indian Buddhism and later translated and transmitted in Tibet. The Tengyur includes commentaries, treatises, and teachings of the great Buddhist scholarly lineages, among which the Yogācāra-Mādhyamika tradition is prominent — the union of the two most profound schools of Mahayana thought.

Within the context of the Northern Canon tradition, this treatise serves the purpose of illuminating the central meaning of the Mahayana sutras, especially the teachings on the nature of mind, reality (suññatā), and the bodhisattva path. The authors of treatises in this period — noble beings such as Asaṅga, Vasubandhu, and Candrakīrti — sought to harmonize the directness of meditation with the clarity of analytical wisdom.

Main Content

Although the title has not been specifically identified, based on Toh 2158’s position in the Treatise Canon, it is likely to discuss fundamental themes of the Mahayana Buddha Dharma. Treatises in this range often focus on three topics:

First, the nature of mind (Ālaya-Vijñapti — storehouse consciousness), which is the basis of all phenomena. According to Yogācāra, mind is not something that “possesses” or “manages” the world, but is itself the source that produces the images of the world. Understanding this is the first step toward liberation from attachment.

Second, the theory of the Buddha grounds and the bodies of the Buddha (Trikāya — the three bodies), in which the Dharma body (Dharmakāya) is understood as ultimate reality without form, the enjoyment body (Sambhogakāya) as the subtle manifestation for bodhisattvas, and the emanation body (Nirmāṇakāya) as the Buddhas who appear in embodiment to teach beings. These three bodies are all one, yet manifest according to the needs of beings.
