2.10

六報土淨穢所居別者，《涅槃經》佛報土指在西方，過三十二恒河沙佛土有釋迦報土，為三乘權學垢淨未亡，見此娑婆穢惡不淨，如來於是權指報土在於西方。《華嚴》實教法門，則此娑婆世界清淨無垢，十方世界清淨無瑕，為實教菩薩垢淨盡故，境界純淨。權教菩薩，無垢淨處自生穢故，故指報土在於西方。

Sixth, the difference in the purity or defilement of the dwelling in the reward land: In the Mahāparinirvāṇa Sūtra, the Buddha's reward land is indicated to be in the west; beyond Buddha-lands as numerous as thirty-two sands of the Ganges, there is Śākyamuni's reward land. Because the defilement and purity of provisional learners of the three vehicles had not yet been eliminated, they saw this Sahā world as defiled, evil, and impure; the Tathāgata thereupon provisionally indicated that the reward land was in the west. In the Dharma door of the ultimate teaching of the Avataṃsaka, this Sahā world itself is pure and undefiled, and the worlds of the ten directions are pure and flawless; because the defilement and purity of the bodhisattvas of the ultimate teaching have been exhausted, the realm is purely clean. For bodhisattvas of the provisional teaching, where there is no defilement or purity, they spontaneously produce defilement; hence he pointed to the reward land as being in the west.
