無量壽經優婆提舍願生偈註 1.20

1.20

此二句名莊嚴種種事功德成就。佛本何故起此莊嚴？見有國土，以泥土為宮飾、以木石為華觀，或彫金鏤玉意願不充，或營備百千具受辛苦，以此故興大悲心，願我成佛必使珍寶具足、嚴麗自然，相忘於有餘、自得於佛道。此莊嚴事，縱使毘首羯磨工稱妙絕，積思竭想豈能取圖？性者本義也。能生既淨，所生焉得不淨？故經言「隨其心淨則佛土淨」。是故言備諸珍寶性，具足妙莊嚴。

These two lines are named the perfection of the merit of adorned diverse affairs. Why did the Buddha originally give rise to this adornment? He saw that there are lands that use mud and clay for palace ornamentation and timber and stone for magnificent views, or carve gold and engrave jade without fulfilling their wishes, or prepare hundreds of thousands of items while enduring toil and bitterness. For this reason, he gave rise to a mind of great compassion, vowing: "When I become a Buddha, I will certainly cause precious gems to be fully replete, adorned and splendid spontaneously, so that beings forget one another in having more than enough and naturally attain the Buddha path." As for these adorned affairs, even if Viśvakarman’s craft were called exquisitely supreme, how could he ever depict them by exhausting all his thoughts and racking his mind? "Nature" has the meaning of origin. Since that which produces is already pure, how could that which is produced not be pure? Therefore a sūtra says: "In accordance with the purity of their minds, the Buddha land is pure." For this reason, it says: "Endowed with the nature of all precious gems, / It is fully replete with wondrous adornments."
