Exposition of Toh 1509 — Tibetan Treatise Collection

Context

The Tengyur, or Treatise Collection (Tib. bstan 'gyur), is a collection of commentaries and treatises explaining the Kangyur, compiled by the greatest Tibetan Buddhist scholars from the eighth century onward. Toh 1509 is a work within the Northern Buddhist canon, representing the Mahāyāna tradition with the profound influence of Tibetan Vajrayāna Buddhism.

Although the title has not been specifically identified, works in the Treatise Collection are often profound analyses of the Buddha’s Dharma, instructions for practice, or explanations of complex concepts. Its appearance in the Tengyur shows that this work was recognized by great scholars, demonstrating its noble value for learning and practice.

Main Content

In the Tibetan Mahāyāna tradition, treatises often focus on three principal themes: the theory of Buddha-nature, the teachings on loving-kindness and compassion, the bodhisattva ideal, and the path of practice leading to awakening.

Based on the context of the Treatise Collection, Toh 1509 is very likely a commentary offering a deep explanation of fundamental Mahāyāna sutras, or an instruction on contemplation of the middle way (Madhyamaka) and mind-only (cittamātrā), the two most important philosophical branches of Tibetan Buddhism. Works of this type often expound on the nature of mind, the empty nature of phenomena (śūnyatā), and the way to overcome two great obscurations: ignorance concerning self (ātma-moha) and ignorance concerning phenomena (dharma-moha).

The treatise may also be related to the bodhisattva path, the process of cultivation over countless aeons by a bodhisattva through the six pāramitās (ṣaḍ-pāramitā: generosity, discipline, patience, diligence, meditation, and wisdom). This is the heart of the Mahāyāna, where the aim is to realize Buddhahood not only for one’s own liberation but also to rescue immeasurable sentient beings.
