Toh 4265Untitled

An Exposition of Toh 4265—Tengyur (Collection of Treatises)

Background

This text belongs to the Tengyur—the Collection of Treatises of the Northern Tibetan Mahayana tradition, compiled in Tibet during the eighth and ninth centuries, when Indian and Tibetan masters worked together to translate Buddhist treatises. It is a philosophical and practical work (śāstra), not an original sutra, but a profound explanation of teachings transmitted by the Buddha and the communities of bodhisattvas.

The Tengyur contains more than 3,600 works, including scriptural critiques and treatises on consciousness, ethics, and the quintessence of the Vehicle’s path. Toh 4265 forms part of this body of knowledge, reflecting the confluence of ancient Indian wisdom and Tibet’s creative reception of it. It is written in a rigorous argumentative style, intended to help practitioners thoroughly understand the principles of the Buddhadharma so they may practice them with awareness.

Main Content

Although the complete title has not been provided, works in the Tengyur commonly revolve around pivotal Mahayana themes: the nature of Buddha-nature (Buddhadhātu), the bodhisattva path leading to awakening for all sentient beings, the emptiness (śūnyatā) of all dharmas, and the application of dependent origination (pratītyasamutpāda) to liberation from suffering.

This text may approach its subject from a logical perspective: analyzing how phenomena exist, the relationship between phenomena and underlying reality, or how practice cultivates loving-kindness, compassion, sympathetic joy, and equanimity (catvāri brahmavihāra) in order to reach a pure Buddha realm. In the Northern Tibetan tradition, particularly the Gelug school, works such as this are used to train the mind through the stages of clearly understanding theory (parijñāna), contemplation (bhāvanā), and concentrated practice (samādhi).

One important aspect is the connection between cognition (jñāna) and action (kriyā): correct knowledge alone is insufficient; consciousness must be transformed so that one acts in accordance with the Dharma.
