Toh 1400Untitled

An Exposition of Toh 1400 from the Treatise Collection (Tengyur)

Context

Toh 1400 belongs to the Tengyur (the Northern Transmission canon), as part of the Treatise Collection, which consists of explanations and commentaries on the teachings of Mahayana Buddhism. In the Northern Tibetan tradition, the Tengyur is regarded as the authentic explanatory works of great masters such as Nagarjuna, Asanga, and closely connected bodhisattvas. This text reflects the philosophical foundations of Madhyamaka and Yogacara, the two central schools of the Mahayana.

Although the title has not been fully identified, through its listing in the Tengyur catalogue this text contains profound instructions on how to practice, on the nature of consciousness, or on the doctrine of emptiness (śūnyatā) from the perspective of the Northern Tibetan tradition. These are precious materials from the ancient wisdom tradition of Indian Buddhism.

Main Contents

The Treatise Collection in general, and Toh 1400 in particular, focus on clarifying the meaning of the authoritative Sutras. They are not new arguments, but logical and illuminating commentaries based on Buddhist methodology: using reasoning (tarkā) to demonstrate that the phenomenal world has no independent intrinsic nature (svabhāva), and that all things arise dependently through causes and conditions.

In the context of the Northern Tibetan tradition, this text may teach about:

The nature of truth: The distinction between conventional truth (samvṛti-satya), in which everything is relative and exists according to habitual convention, and ultimate truth (paramārtha-satya), the absence of intrinsic nature in all phenomena. This is the foundation for gradually guiding the practitioner toward awakening.

Methods of practice: How to apply analytical wisdom (prajñapti) in order to eliminate mistaken attachments (kleśa), the obscurations (āvaraṇa) within the mind.

Contemporary treatises also often discuss the role of the bodhisattva, one who is committed to liberating immeasurable sentient beings, and practices such as loving-kindness (maitrī), compassion (karuṇā), sympathetic joy (muditā), and equanimity (upekṣā).
