第三明一界無二佛意中，初略種一界無有二佛，第二問答廣辨，答中有三，初舉隨昔願無二佛同出，次明第二佛出應無所益，後明一佛出益多佛出損。

In the third [section], explaining the intent that there are not two Buddhas in one realm: first, briefly stating that there are not two Buddhas in one realm; second, extensive discrimination through question and answer. In the answer there are three parts: first, adducing that in accordance with past vows, two Buddhas do not appear together; next, explaining that the appearance of a second Buddha would be of no benefit; finally, explaining that the appearance of one Buddha brings benefit, while the appearance of multiple Buddhas brings detriment.
