Toh 4175Untitled

Exposition of Toh 4175—The Northern Tibetan Canon

Background

This text belongs to the Tengyur (སྟེན་འགྱུར་), the Treatise Collection of Tibetan Buddhism, an extraordinary collection of more than three hundred volumes of treatises that explain and defend the Dharma, composed by learned Mahayana masters. In the Northern Tibetan (Vajrayāna) tradition, these works are not primary scriptures but doctrinal compositions founded upon Mahayana scriptures translated into Tibetan from the seventh century onward.

Although the original title of Toh 4175 has not yet been fully translated, within the context of the Tibetan Treatise Collection, this work certainly addresses one of Mahayana’s essential themes: the nature of mind, the path of liberation, or the teaching of tathatā (suchness). Tibetan commentators, especially masters of the Nyingma, Kagyu, and Gelug schools, produced such works to transmit and preserve the Dharma in actual practice.

Main Content

Treatises in the Tengyur commonly revolve around the foundation of the Four Noble Truths, interpreted through the lens of Mind-Only (cittamātra) or the perfection of wisdom (prajñāpāramitā). They are not merely philosophical theory but also instructions for meditation and practice.

In the Northern Tibetan tradition, practice is divided into many stages, ranging from “foundational practice” (even before formal initiation) to “esoteric tantric practice.” Every treatise in the Tengyur must address the fundamental question: How can our minds be liberated from ignorance (avidyā) and its accompanying afflictions (kleśa)?

This text almost certainly addresses the concept of “non-self” (anātman) or “śūnyatā” (emptiness)—a central concept in Mahayana. According to the Northern Tibetan tradition, clearly understanding śūnyatā is not an act of cold intellect, but penetrating insight (vipaśyanā) combined with calm-abiding meditation (śamatha), generating the power to transform all ignorance.
