Exposition of the Toh 2645 Sutra — The Prajnaparamita Collection (Northern Canon)

Background

This sutra belongs to the Prajnaparamita collection of the Northern Canon, one of the most important scriptural collections in Mahayana Buddhism. Prajnaparamita means "wisdom that crosses beyond," representing transcendent understanding of the nature of emptiness in all dharmas. The Northern Canon is the Mahayana Buddhist tradition widespread in China, Japan, and other East Asian countries, emphasizing cultivation of the bodhisattva path and awakening for the sake of all sentient beings.

The Prajnaparamita scriptures are transmitted from the time of the Buddha in this world, when he taught the Dharma on Vulture Peak together with the noble bodhisattva Avalokiteshvara and immeasurable bodhisattvas, buddhas, and arhats from other realms of beings. These Dharma methods are regarded as supreme within the Mahayana, because they point out the direct path to buddhahood, not for oneself alone but for the benefit of all sentient beings.

Main Contents

Although the descriptive information does not provide specific details about the content, based on the context of the Prajnaparamita collection, this sutra is directed toward the core matters: the empty nature (shunyata) of all dharmas, selflessness (anatman), and the way to realize Prajnaparamita wisdom in actual practice.

The Prajnaparamita sutras often teach that all dharmic things, including the Buddha, bodhisattvas, and the noble attainments, lack any fixed, independent essence. Ignorance (avidya) is the root cause of suffering, arising from the habitual delusion that dharmas possess self-nature. Through Prajnaparamita wisdom, the practitioner directly recognizes this emptiness, not through theory or inference, but through direct realization (aparoksha-jnana), immediate wisdom without mediation.

For a bodhisattva, this Dharma method is also connected with bodhisattva conduct: the six perfections (paramitas), namely generosity, discipline, patience, diligence, meditative concentration, and wisdom. Prajnaparamita is the final perfection, completing all the others; at the same time, there is no one who perfects anything, because all dharmas are empty.
