Following the classification of Buddhist sutra since the period of the Northern and Southern Dynasties (China), this classified them into the Mahayana Tripitaka, Hinayana Tripitaka and Seiken Shuden (聖賢集伝) and decided that the number of Buddhist scriptures that should be edited into the Tripitaka as 5,048 volumes by designating Mahayana sutra as Godaibu (五大部) of Hannya, Hoshaku (宝積), Taishu (大集), kegon and nirvana.
ここでは、南北朝時代(中国)以来の経典分類法を踏襲して大乗の三蔵と小乗の三蔵および聖賢集伝とに三大別し、そのうち大乗経典を般若、宝積、大集、華厳、涅槃の五大部としたうえで、大蔵経に編入すべき仏典の総数を5048巻と決定した。
