經曰「其佛國土」至「猶如第六天寶」者，述云：此第四、盡國嚴麗。有二：此初、顯國莊嚴也。前成佛者即應佛身願，此土嚴淨即應佛土願也，所謂種種事德成故。論云「備諸珍寶性具足妙莊嚴」故。恢（苦灰切），大也。赫（呼格反），《切韻》云「赤也」，《毛詩》云「赫赫」，師尹註云「赫赫，盛貌也」。焜（胡本反），《切韻》云「火光也」。又作煜（出鞠反），盛也曜也。雜廁入間者，莊嚴分齊，即形相德成故，論云「淨光明滿足如鏡日月輪」故。光赫焜耀者，即妙色德成故，論云「無垢光焰熾明淨曜世間」故。清淨者，即清淨德成故，論云「觀彼世界相勝過三界道」故。莊嚴者，即莊嚴德成，所謂水地空皆莊嚴故。如第六天寶，將彼天倍人，以顯淨土寶勝世間而已。

Regarding the passage from "that Buddha land" to "like the jewels of the sixth heaven": The commentary states: This fourth part exhaustively treats the adornment and splendor of the land. It has two parts: this first reveals the adornment of the land. The former attainment of Buddhahood corresponded to his vows for the Buddha body; the adornment and purity of this land corresponds to his vows for the Buddha land, which is the so-called accomplishment of various objective virtues. As the Treatise says: "It is provided with the nature of all precious jewels, completely equipped with wondrous adornments." Hui (ku + hui) means large. He (hu + ge): the Qieyun says it means "red"; the Mao Commentary on the Shijing says "he he," and the commentary on Shiyin says "he he describes a flourishing appearance." Kun (hu + ben): the Qieyun says it means "the light of fire." It is also written as yu (chu + ju), meaning flourishing and shining. "Interspersed with one another" refers to the demarcations of the adornments, which is the accomplishment of the virtue of physical form. As the Treatise says: "Its pure light is full and complete, like a mirror or the discs of the sun and moon." "Blazing brightly and shining" is the accomplishment of the virtue of wonderful color. As the Treatise says: "Its stainless light flares brilliantly, brightly and cleanly illuminating the worlds." "Pure" is the accomplishment of the virtue of purity. As the Treatise says: "Contemplating the characteristics of that realm, it surpasses the paths of the three realms." "Adornment" is the accomplishment of the virtue of adornment, meaning that the water, the earth, and the sky are all adorned. "Like the jewels of the sixth heaven" takes that heaven, which doubles that of humans, simply to reveal that the jewels of the Pure Land surpass the mundane world.
