Large Prajñāpāramitā Sūtras
The Large Prajñāpāramitā Sūtras (Skt. Mahāprajñāpāramitā, Chinese: 摩訶般若波羅蜜多經; pinyin: Móhē Bōrě Bōluómìduō Jīng; lit. 'Large Perfection of Wisdom Sutra') is a group or family of Mahayana sutras of the Prajñāpāramitā (PP) genre. Modern scholars consider these to be later expansions based on the earlier Aṣṭasāhasrikā Prajñāpāramitā Sūtra, which is seen as a prototype of the Larger sutras.
The various versions and translations of the "Large" Prajñāpāramitā Sūtras contain much shared content, as well as various differences, including being significantly different in terms of length (which is measured in ślokas, often translated as "lines").
