Exposition of Scripture Toh 4280 — Mahayana Tradition of the Northern Canon

Background

Toh 4280 is a scripture belonging to the Tengyur—the collection of treatises of the Mahayana tradition of the Northern Canon—compiled in the context of Buddhism’s development in Tibet from the eighth century onward. The Northern Canon tradition inherited and further developed the profound Mahayana theories of India, particularly those of the Yogācāra and Madhyamaka schools, combining them with indigenous Tibetan thought to create a comprehensive system of practice.

The Tengyur contains more than 3,600 treatises and commentaries by great scholars, intended to clarify the meaning of the scriptures contained in the Kangyur. The works in the Tengyur not only explain the teachings but also provide specific instructions on methods of practice, from the initial steps to the highest states of attainment.

Main Content

Although Toh 4280 has not yet been translated in full, its context within the Tengyur suggests that it is a treatise composed by Tibetan masters to explain profound aspects of the Mahayana Dharma. Works in the Tengyur commonly focus on:

First, theories concerning emptiness (śūnyatā)—the empty nature of all dharmas, explained through Madhyamaka reasoning. Emptiness is not absolute nothingness, but the absence of an independently existing self-nature in phenomena. These treatises guide practitioners beyond mistaken views concerning existence and nonexistence.

Second, instructions concerning mind (citta)—the nature of mind and the levels of consciousness. The Tibetan Yogācāra tradition analyzes in detail how the mind creates the phenomenal world and thereby instructs practitioners in transforming consciousness to attain awakening.

Third, advanced methods of practice (sādhana), including meditation, visualization, and contemplation.
