維摩經玄疏 4.78

4.78

四教明因果不同，故釋迦現佛國有異，如身子螺髻，梵王所見不同；諸天共寶器食，隨其果報，飯色有異，正以稟四教不同，故見佛國有異也。

Because the four teachings clarify causes and effects differently, Śākyamuni's manifestation of the buddha-lands differs, just as Śāriputra and the Brahmā king Śikhin saw differently; and when the devas eat together from a single precious vessel, the color of the rice differs according to their retributions. It is precisely because what is received from the four teachings differs that the vision of the buddha-lands differs.
