Paracanonical texts

"Paracanonical texts" (Pāli: Anupiṭaka; lit.'after piṭaka'), also known as "non-canonical," "extra-canonical," and "post-canonical texts," refers to collected non-canonical or extra-canonical Pāli literature of Buddhism. These texts are considered as important supplements or complements to the core teachings contained in the Tipitaka. The paracanonical texts can be regarded as falling into three historical periods. The first ("classical") period stretches from about the 3rd century BC to about the 5th century AD. The second ("commentarial") period extends from the 5th century to the 11th century, and the third ("modern") period begins with the 12th century.
