俱舍論記 12.55

12.55

「《施設足》中至應知亦爾」者，釋第二、第三及第四句中「逆次」兩字。初引論釋四王。鐵輪王一，謂贍部；銅輪王二，加勝身；銀輪王三，更加牛貨；金輪王四，更加北洲。「契經」已下，會釋經文。依論說四輪，經就勝說，但說金輪。引經證訖，論主解云「金輪既然，轉餘三輪應知亦爾。」或可總是，經文就勝偏說金輪，餘三例釋。

"Regarding 'In the Prajñaptiśāstra [...] one should know that it is also thus': this explains the second and third lines, as well as the two words 'reverse order' in the fourth line. First, the treatise is cited to explain the four kings: the iron-wheel king rules one, namely Jambudvīpa; the copper-wheel king rules two, adding Pūrvavideha; the silver-wheel king rules three, further adding Aparagodānīya; the gold-wheel king rules four, further adding Uttarakuru. From 'The sūtra' onwards, the sūtra text is reconciled and explained. According to the treatise, four wheels are spoken of; the sūtra speaks in terms of the preeminent and mentions only the gold-wheel. Having finished citing the sūtra as proof, the author of the treatise explains: 'Since this is so for the gold-wheel, the turning of the remaining three wheels should be known to be likewise.' Or it can be understood altogether that the sūtra text focuses on the preeminent, mentioning only the gold-wheel, and the remaining three are explained by analogy.
