2.310

經：「習種銅輪二天下，銀輪三天性種性，道品堅德轉輪王，七寶金輪四天下。」

Sūtra: "The lineage of practice [becomes] copper-wheel [kings of] two continents; / The lineage of nature [becomes] silver-wheel [kings of] three continents; / With the firm virtue of the aids to awakening, they are wheel-turning kings, / With the seven treasures and golden wheels [ruling] the four continents."
