維摩義記 1.61

1.61

問曰：穢土乃是眾生自業所招，何關佛事，而言為度示土不淨？釋言：眾生見穢見淨實由自業，然其所見見於佛土，良以佛土淨妙無礙，能隨眾生現種種相，如淨妙珠，能隨眾緣現種種色。佛土隨緣，令人異見，故說為度下劣人故示不淨耳。

Question: An impure land is brought about by the own-karma of sentient beings; what does it have to do with the Buddha's work, such that it is said that in order to liberate them he shows an impure land? Explanation: Sentient beings seeing defilement or seeing purity indeed arises from their own karma; nevertheless, what they see is seen in the Buddha-land. This is truly because the Buddha-land is pure, wondrous, and unimpeded, able to manifest various characteristics in accordance with sentient beings, just as a pure, wondrous jewel can manifest various colors in accordance with various conditions. The Buddha-land conforms to conditions and causes people to see differently; therefore it is said that for the sake of liberating inferior people, he shows an impure land.
