Exposition of Toh 4055 — A Tibetan Treatise

Background

Toh 4055 belongs to the Treatise Collection (Abhidharmapiṭaka) of the Northern Tibetan Canon, the division containing expository texts on Buddhist doctrines composed within the Tibetan Buddhist tradition. The Northern Tibetan tradition, or the Tibetan Vajrayāna tradition, developed upon a Mahayana foundation while extensively integrating teachings about mind (citta) and the nature of reality. The Tengyur (Bstan 'gyur) is a vast collection of treatises, commentaries, and works by ancient masters, translated from Sanskrit and other languages into Tibetan from the eighth through the thirteenth centuries.

This scripture arose from the need to explain the system of Buddhist practice comprehensively, from theoretical understanding to concrete application. The work’s exegetical character indicates that it was composed to clarify complex aspects of the Buddhadharma for students who already possessed a basic knowledge of the Tripiṭaka.

Main Content

Although no specific title has been provided, this work, following the tradition of Tibetan treatises, generally addresses such core subjects as mind and mental factors (cittavyapāra), the various domains of reality (bhāva), and the manner in which understanding these leads to liberation.

In Tibetan Mahayana Buddhism, it is important to recognize that all phenomena lack an independent intrinsic nature (śūnyatā). This is not a doctrine of negation, but a profound recognition of the way things interact with and depend upon one another. Treatises in this tradition often examine how the mind-consciousness (ālaya-vijñāna) interacts with the various aspects of experience. Yogācāra thought—the doctrine of Mind-Only—has profoundly influenced works of this kind.

The teaching may also include classifications of craving (rāga), hatred (dosa), and delusion (moha), together with methods for transforming them into wisdom and compassion.
