維摩經略疏垂裕記 4.13

4.13

Second, the actual doubtful thought. Jingxi says: From "the bodhisattva throughout three [countless] kalpas" onward, the thesis of his doubt is established. The doctrinal thesis of the Tripiṭaka teaching is that the practice of the three kalpas is the practice for a pure land, and its fruition of direct rewards is the same as that of the Buddhas of the ten directions. From "how could" downward, he poses the doubt as a result of what he heard: If the practice of the three kalpas is purifying the Buddha-land, Śākyamuni's land ought now to be pure. This doubts that when Śākyamuni was a bodhisattva his mind was not pure. From "if not" downward, he concludes his doubt. In speaking of "turning upside down," it means doubting the Buddha on account of the land, and doubting the land on account of the Buddha.
