無量壽經連義述文贊 2.156

2.156

經曰「所修佛國」至「無衰無變」者，述云：此後、彰果也。恢廓廣大者，即無量德成故，論云「究竟如虛空廣大無邊際」故。廓（古惡反），《爾雅》「大」也。超勝獨妙者，即土勝也，非諸菩薩境故。建立常然者，因滿果立，無改異故。無衰無變者，不為三災之所壞故。

The sūtra says: "The buddha land cultivated..." up to "without decay and without change." The commentary states: This next reveals the results. "Vast and magnificent" means that immeasurable virtues are accomplished, as the Treatise states: "Ultimately like empty space, vast and boundless." "Magnificent" (kuò, sound of gǔ-è); the Erya says it means "great." "Supremely transcendent and singularly wondrous" means the excellence of the land, because it is not within the realm of the bodhisattvas. "Established and permanently so" means that the causes are fulfilled and the result is established, without altering or changing. "Without decay and without change" means that it is not destroyed by the three calamities.
