However, because it had been a long time since 648 when Taiso (Tang tai zong) gave "Shogyojo," and there is a description in the afterword that 'embroidered by order of the Emperor," there is a theory that this epigraph came to be assessed as a translation by Genjo based on Kumaraju's translation in order to glorify Genjo's great work after his death.
しかしながら太宗(唐)が『聖教序』を下賜した648年から大幅に時間が経過している上、跋文に「勅を奉けて潤色せり」という記載があることから、この碑文は玄奘の没後にその偉業を讃えるために鳩摩羅什の訳文を元に玄奘訳としてまとめられたものではないかとする説もある。
