Toh 4230Untitled

Exposition of Scripture Toh 4230 — The Northern Tradition

Context

Toh 4230 is a work belonging to the Treatise Collection (Abhidharmapiṭaka) of the Mahayana Northern tradition, preserved in the Tibetan Tengyur. It belongs to the period following the transmission of Buddhism to Tibet around the eighth and ninth centuries, when Indian masters such as Vasubandhu and Āryadeva, together with sages of the Madhyamaka and Yogācāra schools, composed works explaining the profound teachings of the Mahayana.

The Treatise Collection of the Northern tradition discusses not only formal Abhidharma but also Mahayana philosophy, especially the teachings on emptiness (śūnyatā) and mind-only (cittamātra). The position of Toh 4230 within the Tengyur suggests that it is a treatise or principal exposition concerning practice, meditation, or teachings on the nature of mind and phenomena.

Main Content

Although its title has not been specifically identified, based on the context of the Mahayana Treatise Collection of the Northern tradition, Toh 4230 very likely discusses one of its central subjects: meditative absorption (dhyāna), contemplation (anupaśyanā), or the nature of consciousness and mental factors (cetasika).

In the Mahayana tradition, practitioners must understand that mind is not an independent entity that exists eternally, but a continuum of mental phenomena arising through causes and conditions. Treatises from this period often emphasize the unity of cognition (jñāna) and the object of cognition, of the knowing subject and the known object—in other words, “mind-only,” according to which no phenomenon exists independently outside the mind.

Moreover, the Mahayana Treatise Collection discusses the stages of practice, beginning with faith (śraddhā), continuing through the practice of the pāramitās and the attainment of bodhicitta, and culminating in Buddhahood. Each stage has its prescribed practices, obstacles to overcome, and assurances bestowed upon the practitioner.
