Dirgha Agama
The Dīrgha Āgama is one of the Buddhist Āgamas. It corresponds to the Dīgha Nikāya of the Pāli Canon.
A Chinese translation of the text attributed to the Dharmaguptaka school is included in the Chinese Buddhist canon. This translation was completed by Buddhayaśas and Zhu Fonian in the Later [Qin dynasty], dated to 413 CE. This recension consists of 30 sūtras in contrast to the 34 suttas of the Dīgha Nikāya of the Pāli Canon. The original Sanskrit text of the Dharmaguptaka recension is lost. However, in the 1990s, extensive fragments of a Sarvāstivādin Sanskrit recension of the Dīrgha Āgama text were discovered. Portions of the Sarvāstivādin recension also survive in Tibetan translation.
