Prajñāpāramitā (Sanskrit: प्रज्ञापारमिता) in Buddhism, means "the Perfection of (Transcendent) Wisdom." The word Prajñāpāramitā combines the Sanskrit words prajñā ("wisdom") with pāramitā ("perfection"). Prajñāpāramitā is a central concept in Mahāyāna Buddhism and its practice and understanding are taken to be indispensable elements of the Bodhisattva Path. The practice of Prajñāpāramitā is elucidated and described in the genre of the Prajñāpāramitā sūtras, which vary widely in length and exhaustiveness. The Perfection of Wisdom Sutras suggest that all things, including oneself, appear as thoughtforms (conceptual constructs). The earliest Mahayana Sutras were of the Prajñāpāramitā type.
