An Explanation of Toh 4120 — The Tibetan Treatise Collection

Background

Toh 4120 is a treatise (śāstra) belonging to the Tengyur—a collection of explanatory and commentarial works based upon the Scripture Collection of the Northern Tibetan Mahayana tradition. The Tengyur (Tenzur) was compiled in Tibet during the twelfth and thirteenth centuries and is the world’s largest collection of Buddhist commentaries, containing more than 3,600 works translated from Sanskrit into Tibetan.

The Treatise Collection, an expanded Abhidharma Piṭaka in the Mahayana context, does not consist of scriptures spoken directly by the Buddha, but of works by eminent Buddhist masters intended to explain, systematize, and deepen the teachings. Although no complete individual title is recorded for Toh 4120, the treatise belongs to the category of works on valid cognition (pramāṇa) or explanations concerning the nature of phenomena (dharma-nirdeśa).

Main Content

In the Northern Tibetan Mahayana tradition, treatises commonly focus upon three principal fields: (1) the theory of causes and conditions and the dharma-dhātu; (2) analysis of the Four Noble Truths through the perspective of bodhisattva Buddha-nature; and (3) means of liberation (upāya) suited to different kinds of sentient beings.

This treatise, included in the Tengyur as Toh 4120, may be a work explaining the nature of the bodhisattva path (bodhisattva-yāna) or the relationship between ultimate reality (paramārtha-satya) and conventional reality (saṃvṛti-satya). Treatises of this kind commonly explore how sentient beings may cultivate bodhicitta—the aspiration to attain enlightenment for the benefit of all.

A distinguishing feature of the Northern Tibetan tradition is its profound integration of analytical wisdom (prajñapti-jñāna) and direct wisdom (aparokṣa-jñāna), so that one not only understands the Dharma but also realizes it. Consequently, this treatise may place particular emphasis upon contemplative cultivation (bhāvanā) combined with reasoning (tarkita), a distinctive path of the Northern Tibetan Mahayana.
