經曰「西方去此」至「名曰安樂」者，述云：此第二、標土已變也。帛謙皆云「所居國土名須摩題，正在西方去此千億萬須彌山佛國」。而今云「去此十萬億剎」者，鉾楯之因，廣如前釋。

Regarding the passage from "going from here to the west" to "named Peace and Sustenance (Sukhāvatī)": The commentary states: This second part indicates that the land has already been transformed. Both Bai [Yan] and [Zhi] Qian say: "The land where he dwells is named Xumoti (Sukhāvatī), right in the west, distant from here by hundreds of thousands of koṭis of Mount Sumeru Buddha lands." Now, as for saying "distant from here by a hundred thousand koṭis of lands," the reason for this contradiction was broadly explained before.
