Exposition of the Prajnaparamita Sutra (Toh 3789) — Northern Mahayana Tradition

Context

This sutra belongs to the Prajnaparamita Sutras of the Northern Canon—one of the most essential collections of scriptures in the Mahayana Dharma. Prajnaparamita, or the “Perfection of Wisdom,” is one of the Six Perfections (Ṣaḍpāramitā) that teach the bodhisattva path—the path of those who aspire to attain Buddhahood in order to liberate all sentient beings.

The Prajnaparamita collection holds a special place in Mahayana Buddhism: it not only presents the doctrine of “emptiness” (śūnyatā), but also points out the path of direct practice for realizing this nature. In the Northern tradition, translations by Amoghagarbha, Paramārtha, and Dharmaratna illuminated the profound aspects of this teaching, exerting a deep influence on Chan, Pure Land, and Esoteric Buddhism.

Main Content

Although the full title of the sutra has not been recorded, scriptures within the Prajnaparamita collection generally revolve around a central theme: the understanding that all dharmas are “without intrinsic nature” (niḥsvabhāvatā). Unlike the Śrāvaka Vehicle, which speaks only of the selflessness of persons (anātman), the Mahayana extends this to the selflessness of dharmas—all phenomena, from matter to consciousness, lack an independent intrinsic nature.

The sutra teaches that prajnaparamita wisdom is neither accumulated knowledge nor logical reasoning, but direct insight into the absence of intrinsic nature in all things. This is “inconceivable wisdom” (acintya-jñāna), transcending all concepts, distinctions, and dualistic oppositions. A bodhisattva who practices the perfection of prajna is not bound by attachment to views, does not grasp at any dharma, and does not even grasp at the Buddha Dharma.

The sutra emphasizes that the practice of prajnaparamita is inseparable from compassion and loving-kindness—the bodhisattvas arouse the resolve to liberate all sentient beings without conceiving of any being who is liberated. This is “skillful means” (upāya-kauśalya): employing beneficial actions and words without being bound by them.
