However, in the aspect of philology the majority of the text was an abstraction from "Maka Hannya Haramitsu-kyo Sutra" of Tripitaka in the Korean edition (in the first part of the thirteenth century) translated by Kumaraju, and was different from the corresponding part of the "Mahaprajnaparamita-sutra" translated by Genjo, so that there is also suspicion about whether it was translated by Genjo, as well as the Buddhist sutra, which was said to be a translation by Raju.
しかし、文献学的にはテキストの主要部分が高麗大蔵経版（13世紀前半）の鳩摩羅什訳『摩訶般若波羅蜜経』からの抽出文そのものであり、玄奘が翻訳した『大般若波羅蜜多経』の該当部分とは異なるため、これも羅什訳と同様に玄奘訳であるということが疑われている。
