Toh 3661Untitled

Exposition of Toh 3661 — The Northern Tibetan Mahayana Tradition

Context

Toh 3661 belongs to the Treatise Collection (Abhidharmakośa-bhāṣya) in the Tengyur of the Northern Tibetan transmission, one of the most profound philosophical Buddhist documents of the Mahayana. The Treatise Collection is a body of commentary on Abhidharma, the teaching that analyzes in detail mental phenomena, material phenomena, and the constituent factors of the world. This is the philosophical foundation for Mahayana practice, especially in the Tibetan tradition (Tibetan Buddhism).

This text was translated into Tibetan from Sanskrit or Chinese originals, reflecting the effort to preserve and develop the Buddha’s teaching within the Tibetan cultural setting. It represents a highly developed stage of the Buddha Dharma, when masters had systematized theory and practice into a complete whole.

Main Content

Although the title has not been fully identified, based on the text’s place in the Treatise Collection, it very likely explains one of the fundamental aspects of Abhidharma: the classification of dharmas, the intrinsic nature of phenomena, or the relation of cause and effect (pratītyasamutpāda).

In the Northern Tibetan Mahayana, Abhidharma is not only a theoretical foundation but also a guide to meditation. It teaches that everything we perceive is composed of basic constituents of mind (skandhas — the five aggregates), and that accurately understanding their nature is the key to liberation. This text, like other texts in the Tengyur, emphasizes that non-self (anātman) is not the destruction of existence, but the clear realization that there is no fixed, eternal “self” governing phenomena.

Unlike the Lesser Vehicle, the Mahayana expands this understanding: not only persons, but also dharmas lack any absolute intrinsic nature (śūnyatā — emptiness). This leads to a more open view, where rejection is replaced by compassion and bodhicitta, the aspiration for liberation for the sake of all beings.
