經曰「阿難白佛」至「成佛現在」者，述云：第二、申所成果。即身土之果，逐誓願而成故。有二：初、略申所成；後、廣顯所成。初又有四：此初、辨佛既成也。即主德成故。論云「正覺阿彌陀法王善住持」故。

Regarding the passage from "Ānanda addressed the Buddha" to "at present has attained Buddhahood": The commentary states: Second is explaining the fruit that was accomplished. That is the fruit of the body and the land, which was accomplished following his vows. There are two parts: first, briefly explaining what was accomplished; second, broadly revealing what was accomplished. The first further has four parts: this first is explaining that the Buddha has already accomplished it. That is because the virtue of the Master was accomplished. As the Treatise says: "The Correctly Enlightened Amitāyus, the Dharma King, well sustains it."
