Toh 4255Untitled

Exposition of Tengyur Scripture Toh 4255

The Treatise Collection of the Tibetan Tradition

Background

Toh 4255 is a treatise (śāstra) belonging to the Tengyur—a collection of commentaries and expositions on the Buddhadharma compiled in Tibet from the ninth century onward. The Tengyur contains more than three hundred works of instruction and explanation, representing the Northern Mahāyāna tradition inherited from India through schools such as Yogācāra, Madhyamaka, and Tibetan Buddhism.

Although no specific title has been recorded, this scripture forms part of the canonical treasury translated and transmitted by eminent Tibetan monks to preserve and develop the Dharma methods of Northern Buddhism. In the context of the Northern Tibetan tradition, these treatises commonly focus on two principal foundations: the theory of the nature of consciousness and the path of practice leading to awakening.

Main Content

Treatises in the Tengyur such as Toh 4255 commonly explore essential issues of the Mahāyāna Buddhadharma. They may concern the bodhisattva class, the theory of Buddha-nature, or advanced methods of meditation (dhyāna). The Tibetan tradition particularly emphasizes:

First, the emptiness of intrinsic nature (śūnyatā) of all phenomena—the concept that no phenomenon exists independently or possesses a fixed essence. This is not absolute nonexistence, but the absence of inherent nature (svabhāva).

Second, mind (citta) is regarded as the ultimate reality that may be cultivated directly through methods such as Dzogchen (Mahāti Yoga) or Mahāmudrā—distinctive features of this tradition.

Third, the bodhisattva path includes the six pāramitās: generosity, ethical discipline, patience, diligence, meditative concentration, and wisdom. This treatise may explain how bodhisattvas develop compassion (karuṇā) so that all sentient beings may attain nirvana.
