Toh 3480Untitled

Commentary on the Toh 3480 Koan from the Tengyur

Context

The Tengyur is a collection of Buddhist Dharma treatises comprising more than 200 volumes, translated from Sanskrit into Tibetan during the flourishing period of Tibetan Buddhism (approximately the eleventh to fourteenth centuries). The Toh 3480 koan lies within the Treatise Collection, where commentaries, explanations, and developments of thought from the Mahayana sutras are preserved.

In the Northern Transmission Tibetan tradition, the Treatise Collection is regarded as supplementary teachings that help devotees understand more deeply the Dharma topics of Buddha Shakyamuni. These treatises were often composed by eminent teachers on the basis of direct experience in practice and understanding of the nature of mind. This koan especially reflects the spirit of Yogācāra and Madhyamaka, two Mahayana philosophical schools that had profound influence in Tibet.

Main Content

Although the title has not been fully published, this koan belongs to the line of commentaries analyzing the nature of mind and cognitive phenomena. In the Yogācāra-Madhyamaka spirit of the Northern Tibetan tradition, the content focuses on exploring the relationship between the sacred dimension (dharmadhātu) and the manifestation of phenomena as self-existing (svabhāva).

This treatise affirms that all that we perceive, forms, sounds, sensations, arises from mind and does not exist independently outside it. This is not an idealist doctrine that denies the external world, but the position that the movement and description of phenomena are always examined through the filter of consciousness. The koan may also address how “mind itself” (sems nyid) is Buddha-nature, that is, in the sense of its innate clarity and unstained quality.

On this foundation, the treatise explains why the Buddhadharma does not require us to flee the world, but to transform the way we perceive it and relate to it. The path of liberation lies in recognizing the empty nature of the “self” (anātman) and our ignorant attachment to mistaken concepts.
