瑜伽師地論略纂 1.112

1.112

四寶成山中，《俱舍論》說西頗胝迦，北面金，與此不同，宗異故。其輪王路，俱言繞此洲；王四天之相，餘處亦有；或往餘處飛空而行故，唯此有洲其金路。此雖說金輪王，何廢餘王？有設拉末梨，似皂角樹，此所無也。　卵生鳥居東面，以羽激水二百由旬，取卵生龍；胎生居南面，激四百由旬，取胎卵龍；濕生居西，激八百由旬，取三，除化生；化生居北，激一千六百由旬，取四生龍，隨應食之。廣如經說。何經勘。

Regarding the mountain composed of four jewels: the Abhidharmakośa-śāstra states that the western face is crystal and the northern face is gold, which differs from this text because the schools are different. As for the road of the wheel-turning king, both state that it encircles this continent; signs of a king of the four heavens also exist elsewhere; or because when traveling to other places they fly through the air, only this continent has its golden road. Although this mentions the gold-wheel-turning king, why would it exclude the other kings? There is the śālmali tree, which resembles a honey locust tree, not found here. The egg-born birds dwell on the eastern face; beating the water for two hundred yojanas with their wings, they seize egg-born nāgas. The womb-born dwell on the southern face; beating four hundred yojanas, they seize womb-born and egg-born nāgas. The moisture-born dwell on the west; beating eight hundred yojanas, they seize three [types], excluding the apparitionally born. The apparitionally born dwell on the north; beating one thousand six hundred yojanas, they seize nāgas of the four kinds of birth, eating them as appropriate. This is explained extensively as in the sūtras. Check which sūtra.
