The term is the transliteration of the Sanskrit word prajñā, meaning wisdom. It refers to the supreme wisdom with insight into the nature and reality of all things. Buddhism believes that such wisdom surpasses all secular understandings, and therefore is the guide for or essence of the effort aimed at achieving enlightenment and attaining Buddhahood or bodhisattvahood. This wisdom has no form, no appearance, and cannot be expressed in words. It can only be achieved by undertaking a variety of accessible Buddhist practices.
Prajñã is the wisdom that surpasses all common or ordinary knowledge and specific understandings. (Sengzhao: Treatises of Sengzhao)
