Exposition of the Treatise Collection (Toh 4246) — The Northern Mahayana Canonical Tradition

Background

This work was once part of the Treatise Collection (Tengyur)—the collection of profound Buddhist treatises and commentaries translated from Sanskrit into Tibetan between the eighth and twelfth centuries. The Tengyur contains more than 3,600 works by Indian Buddhist masters, particularly from the Madhyamaka, Yogācāra, and Abhidharma traditions. Although this text (Toh 4246) has not retained a clear title in the modern tradition, it forms part of a profound body of scripture intended to defend, explain, and develop Mahayana principles.

The historical context of the Tengyur is closely connected with the efforts of Tibetan Dharma masters such as Rinchen Zangpo and Lotsāwa Marpa to preserve and propagate the teachings of Mahayana Buddhism before Buddhism declined in India. These treatises are regarded as the foundation of modern Tibetan philosophy.

Main Content

Although the specific title has not been fully identified, works of this kind in the Tengyur commonly revolve around key Mahayana themes: the nature of consciousness (citta-svabhāva), theories of the bodhisattva path, or arguments concerning emptiness (śūnyatā). In the Tibetan tradition, these treatises are not only theoretical explanations but also direct guides to practice.

Classical Tibetan masters, particularly those of the Gelug, Nyingma, or Kagyu traditions, relied upon works in the Tengyur to develop comprehensive systems of practice. These treatises commonly present: (1) precise definitions of Buddhist concepts through comparative methodology, (2) refutations of mistaken understandings held by other schools, and (3) a practical path of cultivation based upon theory.

Like other works in the Tengyur, this text particularly emphasizes the interconnection between theory and practice, reflecting the Mahayana principle that correct understanding (prajñapti-sat) must lead to awakening and compassion (karuṇā).
