Meanwhile, the original Sanskrit text of "Kanmuryoju-kyo Sutra" has not been discovered, so it is assumed that its broad outline was established in Central Asia around 4-5 A.D. and that factors related to China were added during the process of translation.
なお、『観無量寿経』は、サンスクリットの原典が発見されておらず、おそらく4-5世紀頃中央アジアで大綱が成立し、伝訳に際して中国的要素が加味されたと推定される。
