Exposition of Toh 3731 — The Tengyur Treatise Collection

Context

Toh 3731 belongs to the Treatise Collection (Tengyur) of the Northern Transmission Mahayana tradition, a part of the treasury of Buddhist scriptures compiled and preserved in Tibet from the eighth century onward. The Tengyur is a collection of expositions, annotations, and works by great Buddhist masters, regarded as important explanations intended to interpret the principal scriptures (Kangyur) in depth.

In the context of the Mahayana tradition, especially the Tibetan Vajrayana lineage, these expositions are not merely scholarly commentaries but also closely related practical instructions, helping practitioners understand the profound meaning of the Dharma and apply it to a concrete path of practice. Each exposition bears the mark of a bodhisattva or of highly virtuous masters who have realized the Truth.

Main Content

Although the title of the scripture has not yet been clearly identified, the expositions in the Tengyur often focus on core Mahayana themes such as: the doctrine of Buddha-nature, Suchness (Tathatā), or the elements of the Bodhisattva path. These treatises often deeply explore the nature of mind (cittā), non-self (anātmā), and the skillful means (upāya) used by the Buddha to guide sentient beings.

In the Tibetan tradition, such expositions also emphasize the relationship between ultimate truth (Paramartha-satya) and conventional truth (Samvriti-satya), helping students realize that these two truths are not separate but are unified in the clear mind. This is the foundation of wisdom (prajñā) — awakening to the true nature of reality of all dharmas.

The theories presented are not separate from practice. The Tengyur provides concrete guidance on how to cultivate the mind, arouse the Bodhisattva mind, practice concentration (samādhi) and wisdom (prajñā), especially through methods such as meditative cultivation (bhāvanā) and recollection (smarana).
