Toh 3355Untitled

Exposition of the Prajnaparamita Sutra (Toh 3355)

Context

The Prajnaparamita Collection (Prajnaparamita — “the path of the perfection of wisdom”) is a collection of the most essential scriptures of the Northern Mahayana tradition. This sutra belongs to the Northern Canon (Tibetan) and is preserved in the Kangyur Collection under the catalog number Toh 3355. Prajnaparamita is the core teaching of the bodhisattva path, emphasizing transcendent wisdom capable of penetrating the empty nature of phenomena.

In the Mahayana context, prajnaparamita is not ordinary knowledge but direct insight into the non-self (anatman) nature of all dharmas. The Tibetan tradition especially values the Prajnaparamita scriptures because they provide the philosophical foundation for schools such as Madhyamaka and Yogacara. The sutra was compiled from various translations, reflecting the widespread process of translation in western Tibet during the ninth to eleventh centuries.

Main Content

Although there is no specific title, the Prajnaparamita sutras in Toh 3355 generally focus on the Buddha’s instruction to bodhisattvas and on questions and answers concerning the nature of transcendent wisdom. The sutra emphasizes that prajnaparamita cannot be described in ordinary language, because it itself transcends all dualistic concepts (subject-object, existence-nonexistence).

In a typical mode of teaching, the Buddha explains that the bodhisattva studies and practices prajnaparamita not in order to attain something new, but in order to realize that there is nothing that needs to be attained. All phenomena — the things we regard as reality — are empty in nature, without immutable self-nature (svabhava). Whenever a bodhisattva tries to cling to the concepts “I am cultivating” or “I am practicing,” that is an obstruction in the practice of prajnaparamita.

The sutra also aims to correct the mistaken discrimination among dharmas, guiding practitioners not to reject or cling tightly to any dharma, including even wholesome dharmas.
