大方廣佛華嚴經隨疏演義鈔 27.14

27.14

疏「俱舍」云者，略其義耳。具足頌云「東毘提訶洲，其形如半月，三邊如贍部，南邊三百半。南贍部如車，三邊各二千，南邊三百半。西瞿陀尼洲，其相圓無缺，逕二千五百，周圍此三倍。北俱盧畟方，面各二千等。」東則北闊南狹，餘可知。故結云「四洲相殊」。從「今云如者」，上舉論為問，今為會釋。言「全似此界」者，此四洲安布是一佛居，今此世界同此四洲之界耳。

Regarding the Commentary's citation of the "Kośa": this merely abbreviates its meaning. The complete verse says: "The continent of Pūrvavideha / Is shaped like a half-moon: / Three sides are like Jambūdvīpa, / Its southern side is three hundred and a half. / Southern Jambūdvīpa is like a cart: / Its three sides are each two thousand, / Its southern side is three hundred and a half. / The continent of Aparagodānīya / Has a round form without flaw, / With a diameter of two thousand five hundred, / Its circumference three times this. / Uttarakuru is square, / Each side equally two thousand." The east is broad in the north and narrow in the south; the rest may be known. Therefore it concludes: "The characteristics of the four continents differ." From "now saying 'like'", the treatise was raised above as a question, and now it is harmonized and explained. The phrase "entirely like this realm" means: the arrangement of these four continents is the dwelling of a single Buddha; now this world is identical to the realm of these four continents.
