What does prajna mean?
Prajna is a term from Indian religious and philosophical traditions meaning deep, penetrating wisdom or insight. Its central idea is understanding the true nature of reality rather than merely possessing information or following a conceptual description. Buddhist sources use it especially for the insight that directly apprehends impermanence, suffering, non-self, or emptiness. In Jain thought, prajna similarly denotes direct knowledge of the true reality of things. It is commonly paired with samadhi, meaning meditative concentration: samadhi steadies the mind, while prajna supplies liberating insight. In English, the term is normally associated with Buddhist scripture, meditation traditions, and academic discussion. It is not a general synonym for intelligence, although it can sometimes be used more loosely. The related Sanskrit compound prajñāpāramitā, meaning the perfection of wisdom, became especially important in Mahayana Buddhist literature.

"The bodhisattva's prajna revealed the true nature of suffering without grasping it as permanent."
"Through prolonged practice, the monk developed prajna and understood impermanence without relying on concepts alone."
"The treatise contrasts conventional understanding with prajna, the direct insight into emptiness."
The plural is uncommon because prajna is normally used as an abstract or mass noun.
"The text describes the prajnas of bodhisattvas who have directly realized emptiness."
The Prajñāpāramitā literature, including the Heart Sutra, made wisdom itself the central subject of Buddhist teaching.

Where does prajna come from?
The word comes from Sanskrit prajñā, formed from the verbal root jñā-, “to know,” and is related to jñāna, “knowledge.” Its Pali cognate is paññā, while forms such as vijñāna and abhijñāna also preserve the same root with different prefixes and meanings. Sanskrit prajñā was adopted into Buddhist and Jain philosophical vocabulary, where it developed a technical sense of direct or liberating insight. The compound prajñāpāramitā, “the perfection of wisdom,” became a major scriptural tradition in Mahayana Buddhism.
How prajna is actually used
This is a learned religious and philosophical term rather than everyday vocabulary. Scholars and translators often print it as prajñā, with the final diacritic marking the long vowel; the anglicized form prajna is also common.
Easily confused with prajna
Samadhi is meditative concentration or absorption, whereas prajñā is the insight or wisdom that directly understands the true nature of reality.
