Toh 2650Untitled

Exposition of Scripture Toh 2650 (Treatise Collection)

Context

Toh 2650 is one of the precious treatises recorded in the Tengyur, the treasury of Buddhist Dharma commentaries by Mahayana noble ones and sages, translated from Sanskrit into Tibetan in the eighth and ninth centuries. The Northern Tibetan tradition (Tibetan Buddhism) especially values these treatises as guiding lights for deeply understanding the scriptures and applying the teachings in practice.

Although the exact title of the scripture is not clearly recorded, according to its classification in the Tengyur, this is a treatise belonging to the Middle Treatises, works focused on central Mahayana teachings such as the nature of Buddha-nature, emptiness (śūnyatā), and mind (citta). A special feature of this tradition is the profound union of philosophical reasoning and meditative practice for spiritual transformation.

Main Content

In the context of the Treatise Collection, Toh 2650 continues the tradition of explaining Buddhist Dharma concepts in detail through logic and argumentation. This treatise directs the student’s attention to one of the important foundations of Mahayana: the naturally luminous quality (prakṛti-prabhāsvara) of mind. According to the Northern Tibetan tradition, mind (citta) is by nature not material, not a composite of unconscious elements, but luminous, self-illuminating.

This scholastic scripture explores how the human mind is able to recognize mental defilements (kleśa) precisely because of its clear nature. These defilements, such as greed, hatred, and delusion, adhere to the mind like dust on the surface of a mirror, but never alter its essence. From this recognition arises confidence that Buddha-nature (buddhadhātu) is the potential present in all beings.

The treatise also emphasizes the role of cultivation (bhāvanā) in purifying this mind. Practice does not create a new luminous mind, but reveals the luminous nature already present by removing the coverings of ignorance (avidyā).
