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.
