Toh 2644Untitled

Exposition of the Prajnaparamita Sutra (Toh 2644) — The Northern Mahayana Tradition

Background

This sutra belongs to the Prajnaparamita collection (Prajnaparamita, the Perfection of Wisdom), one of the core scriptural bodies of the Northern Mahayana tradition. The Prajnaparamita collection comprises a series of sutras, from short to long, developed from the teachings of Shakyamuni Buddha on Vulture Peak. In the Mahayana tradition, especially in China, Tibet, and the countries of East Asia, Prajnaparamita is regarded as the "principal sutra" of all sutra collections, because it directly presents the nature of the Perfection of Wisdom, the key to liberation from samsara.

This Toh 2644 text is preserved in the Northern Canon of Tibet as part of the Kangyur, the collection of the Buddha's words, translated from Sanskrit into Tibetan in the ninth to tenth centuries. The status of this sutra reflects the Mahayana emphasis on the bodhisattva path: the aim is not merely to attain personal nirvana, but to awaken for the benefit of all sentient beings.

Main Contents

Although the title of the sutra has not been fully provided, based on Toh 2644's position within the Prajnaparamita collection, this sutra certainly develops the core teachings of this tradition: emptiness (shunyata) and the absence of self-nature (anatman) in all phenomena. Prajnaparamita is not a philosophical theory but a direct experience of wisdom, an understanding of the unborn, unceasing, non-identical, and non-different nature of all dharmas.

In the spirit of the Northern Mahayana tradition, this sutra may portray bodhisattvas such as Avalokiteshvara or Kshitigarbha, figures symbolizing the union of compassion and wisdom, guiding sentient beings on the path of practice. The teaching of Prajnaparamita here is presented not only through reasoning but through direct interaction between the Buddha and the bodhisattvas, between Dharma and practice.
