EXPLANATION OF TOH 2120 — TENGYUR

Context

Toh 2120 is a work belonging to the Tengyur (Bkah 'gyur — the Tibetan Treatise Collection), a collection of Buddhist treatises and commentaries compiled and preserved within the Northern Mahayana Tibetan tradition. The Tengyur contains hundreds of works by Indian Buddhist masters, translated into Tibetan between the eighth and thirteenth centuries.

The Northern Tibetan tradition (Vajrayāna, or Tibetan Buddhism) is a branch of Mahayana that profoundly developed teachings on the nature of mind, Buddha-nature, and the path of tantric practice. The treatises in the Tengyur are not scriptures taught directly by the Buddha, but explanations and practical instructions written by enlightened masters on the basis of ancient Mahayana scriptures.

Although its original title has not yet been fully identified, Toh 2120 is among the important works forming the doctrinal foundation of this tradition. This reflects Tibetan Buddhism’s commitment to logical reasoning, profound analysis of the nature of mind, and the integration of practice with theory.

Main Content

Treatises in the Tengyur commonly focus on three principal fields: Abhidharma (the study of mind and phenomena), Madhyamaka (the Middle Way school—the emptiness of all dharmas), and Yogacara (the Mind-Only school—the nature of consciousness). Like similar works, Toh 2120 is likely either a commentary or an independent treatise explaining one or more aspects of these teachings.

In the Northern Tibetan tradition, treatises are always directed toward concrete practical aims. They are not merely abstract theories, but also direct instructions for practitioners who wish to cultivate profound wisdom (prajñā—the gift of bodhi) and immeasurable loving-kindness and compassion (maitrī, karunā). These works commonly:

Analyze how the mind functions and the results of actions (karma) within the cycle of birth and death. Instruct practitioners in recognizing the emptiness (śūnyatā)—the absence of a fixed self—of all phenomena. Provide methods of meditation and contemplation for purifying consciousness and developing the qualities of a Buddha.
