仁王經疏 2.113

2.113

釋曰：自下第二廣釋十地。即分為十，此即第一釋善覺地。文分為五：一居土寬狹、二配屬王位、三顯習法門、四釋地別行、五辨地通業。住百佛國者，居土寬狹。《本記》云「國土有三：一說法土，百億日月，化小乘；二神通土，億億日月，化中乘；三智慧土，無量世界，化菩薩。」今言百佛國土者，說法土也。言作閻浮四天王者，配屬王位。

Explanation: From here below, the second part explains the ten bhūmis in detail. It is divided into ten; this is the first, explaining the stage of Good Awakening. The text is divided into five parts: first, the extent of the land inhabited; second, correlating to royal status; third, revealing the dharmamukha practiced; fourth, explaining the distinct practices of the stage; fifth, discerning the common karma of the stage. Abiding in a hundred buddha-lands refers to the extent of the land inhabited. The Original Commentary says: "Buddha-lands are of three kinds: first, lands of preaching the Dharma, with ten billion suns and moons, transforming the small vehicle; second, lands of supernatural powers, with a hundred billion suns and moons, transforming the middle vehicle; third, lands of wisdom, with immeasurable world realms, transforming bodhisattvas." Now, saying "a hundred buddha-lands" refers to the lands of preaching the Dharma. Saying "becoming a Jambudvīpa king of the four heavenly kings" correlates to royal status.
